Accounting Policies [Abstract]
OVERVIEW AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	1	OVERVIEW, BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

	Overview. Agilent Technologies Inc. ("we", "Agilent" or the "company"), incorporated in Delaware in May 1999, is a global leader in life sciences, diagnostics and applied chemical markets, providing application focused solutions that includes instruments, software, services and consumables for the entire laboratory workflow.

	Our fiscal year-end is October 31, and our fiscal quarters end on January 31, April 30 and July 31. Unless otherwise stated, these dates refer to our fiscal year and fiscal quarters.

	Keysight Separation. On November 1, 2014, we completed the distribution of 100% of the outstanding common shares of Keysight Technologies, Inc. ("Keysight") to Agilent stockholders who received one share of Keysight common stock for every two shares of Agilent held as of the close of business on the record date, October 22, 2014. The historical results of operations and the financial position of Keysight are included in the consolidated financial statements of Agilent and are reported as discontinued operations within this Form 10-Q. See "Basis of Presentation".

	New Segment Structure. In November 2014, we announced a change in organizational structure designed to better serve our customers. Our life sciences business, excluding the nucleic acid solutions division, together with the chemical analysis business combined to form a new segment called life sciences and applied markets business. Our diagnostics and genomics businesses combined with the nucleic acid solutions division from our life sciences business and became the diagnostics and genomics segment. Finally, the Agilent CrossLab segment was formed from the services and consumables businesses previously part of the life sciences and chemicals analysis businesses. Financial reporting under this new structure is included within this report on Form 10-Q and historical financial segment information has been recast to conform to this new presentation within our financial statements.

	Basis of Presentation. We have prepared the accompanying financial data for the three months ended January 31, 2015 and 2014 pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles (“GAAP”) in the U.S. have been condensed or omitted pursuant to such rules and regulations. The accompanying financial data and information should be read in conjunction with our Annual Report on Form 10-K.

	In the opinion of management, the accompanying condensed consolidated financial statements contain all normal and recurring adjustments necessary to present fairly our condensed consolidated balance sheet as of January 31, 2015 and October 31, 2014, condensed consolidated statement of comprehensive income for the three months ended January 31, 2015 and 2014, condensed consolidated statement of operations for the three months ended January 31, 2015 and 2014, and condensed consolidated statement of cash flows for the three months ended January 31, 2015 and 2014.

	The prior year results of operations and the prior year end financial position of Keysight are included in the consolidated financial statements of Agilent and reported as discontinued operations. The prior year statement of comprehensive income and prior year statement of cash flows have not been adjusted to reflect the effect of the separation of Keysight. Unless indicated otherwise, the information in the Notes to the condensed consolidated financial statements relates to our continuing operations.

	Use of estimates. The preparation of condensed consolidated financial statements in accordance with GAAP in the U.S. requires management to make estimates and assumptions that affect the amounts reported in our condensed consolidated financial statements and accompanying notes. Management bases its estimates on historical experience and various other assumptions believed to be reasonable. Although these estimates are based on management’s best knowledge of current events and actions that may impact the company in the future, actual results may be different from the estimates. Our critical accounting policies are those that affect our financial statements materially and involve difficult, subjective or complex judgments by management. Those policies are revenue recognition, valuation of goodwill and purchased intangible assets, inventory valuation, share-based compensation, retirement and post-retirement plan assumptions, restructuring and accounting for income taxes.

	Update to Significant Accounting Policies. For the stock option and long term performance plan grants in 2015 we are now using a volatility measure derived from a selection of our peer companies. In prior periods, we used Agilent stock historical volatility. We now consider this method to not be reflective of our future volatility due to the separation of Keysight. See Note 4, "Share-based compensation" for additional information. There have been no other material changes to our significant accounting policies, as compared to the significant accounting policies described in our Annual Report on Form 10-K for the fiscal year ended October 31, 2014.

	Fair Value of Financial Instruments. The carrying values of certain of our financial instruments including cash and cash equivalents, accounts receivable, accounts payable, accrued compensation and other accrued liabilities approximate fair value because of their short maturities. The fair value of long-term equity investments is determined using quoted market prices for those securities when available. For those long-term equity investments accounted for under the cost or equity method, their carrying value approximates their estimated fair value. Equity method investments are reported at the amount of the company’s initial investment and adjusted each period for the company’s share of the investee’s income or loss and dividend paid. The fair value of our long-term debt, calculated from quoted prices which are primarily Level 1 inputs under the accounting guidance fair value hierarchy, exceeds the carrying value by approximately $45 million and $53 million as of January 31, 2015 and October 31, 2014, respectively. The fair value of foreign currency contracts used for hedging purposes is estimated internally by using inputs tied to active markets. These inputs, for example, interest rate yield curves, foreign exchange rates, and forward and spot prices for currencies are observable in the market or can be corroborated by observable market data for substantially the full term of the assets or liabilities. See also Note 9, "Fair Value Measurements" for additional information on the fair value of financial instruments.

	Goodwill and Purchased Intangible Assets. Under the authoritative guidance we have the option to perform a qualitative assessment to determine whether further impairment testing is necessary. The accounting standard gives an entity the option to first assess qualitative factors to determine whether performing the two-step test is necessary. If an entity believes, as a result of its qualitative assessment, that it is more-likely-than-not (i.e. greater than 50% chance) that the fair value of a reporting unit is less than its carrying amount, the quantitative impairment test will be required. Otherwise, no further testing will be required.

	The guidance includes examples of events and circumstances that might indicate that a reporting unit's fair value is less than its carrying amount. These include macro-economic conditions such as deterioration in the entity's operating environment or industry or market considerations; entity-specific events such as increasing costs, declining financial performance, or loss of key personnel; or other events such as an expectation that a reporting unit will be sold or a sustained decrease in the stock price on either an absolute basis or relative to peers.

	If it is determined, as a result of the qualitative assessment, that it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount, the provisions of authoritative guidance require that we perform a two-step impairment test on goodwill. In the first step, we compare the fair value of each reporting unit to its carrying value. The second step (if necessary) measures the amount of impairment by applying fair-value-based tests to the individual assets and liabilities within each reporting unit. As defined in the authoritative guidance, a reporting unit is an operating segment, or one level below an operating segment. We aggregate components of an operating segment that have similar economic characteristics into our reporting units.

	In fiscal year 2014, we assessed goodwill impairment for three reporting units under our previous reporting structure which consisted of one segment: chemical analysis and two reporting units under the life sciences and diagnostics segment. The first of these two reporting units related to our life sciences business and the second related to our diagnostics business. We performed a qualitative test for goodwill impairment of our previous three reporting units as of September 30, 2014. Based on the results of our qualitative testing, we believe that it is more-likely-than-not that the fair value of these reporting units are greater than their respective carrying values. Each quarter we review the events and circumstances to determine if goodwill impairment is indicated. In connection with our annual goodwill impairment testing in 2015, we will assess for potential impairment of goodwill on our new reporting units resulting from our reorganization. In the three months ended January 31, 2015 and 2014, there was no triggering event that would indicate that there was an impairment of goodwill therefore there was no impairment of goodwill during the three months ended January 31, 2015 and 2014.

	Purchased intangible assets consist primarily of acquired developed technologies, proprietary know-how, trademarks, and customer relationships and are amortized using the best estimate of the asset's useful life that reflect the pattern in which the economic benefits are consumed or used up or a straight-line method ranging from 6 months to 15 years. In-process research and development ("IPR&D") is initially capitalized at fair value as an intangible asset with an indefinite life and assessed for impairment thereafter. When the IPR&D project is complete, it is reclassified as an amortizable purchased intangible asset and is amortized over its estimated useful life. If an IPR&D project is abandoned, Agilent will record a charge for the value of the related intangible asset to Agilent's condensed consolidated statement of operations in the period it is abandoned.

	Agilent's indefinite-lived intangible assets are IPR&D intangible assets. The accounting guidance allows a qualitative approach for testing indefinite-lived intangible assets for impairment, similar to the issued impairment testing guidance for goodwill and allows the option to first assess qualitative factors (events and circumstances) that could have affected the significant inputs used in determining the fair value of the indefinite-lived intangible asset to determine whether it is more-likely-than-not (i.e. greater than 50% chance) that the indefinite-lived intangible asset is impaired. An organization may choose to bypass the qualitative assessment for any indefinite-lived intangible asset in any period and proceed directly to calculating its fair value. We performed a qualitative test for impairment of indefinite-lived intangible assets as of September 30, 2014. Based on the results of our qualitative testing, we believe that it is more-likely-than-not that the fair value of these indefinite-lived intangible assets is greater than their respective carrying values. Each quarter we review the events and circumstances to determine if impairment of indefinite-lived intangible asset is indicated. There was no impairment of indefinite-lived intangible asset during the three months ended January 31, 2015 and January 31, 2014.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
NEW ACCOUNTING PRONOUNCEMENTS	2. NEW ACCOUNTING PRONOUNCEMENTS

	There were no changes to the new accounting pronouncements as described our Annual Report on Form 10-K for the fiscal year ended October 31, 2014 except for the following:

	In April 2014, the FASB issued amendments to the guidance on discontinued operations. The guidance changes the criteria for reporting discontinued operations while enhancing disclosures in this area. Under the new guidance, only disposals representing a strategic shift in operations should be presented as discontinued operations. Those strategic shifts should have a major effect on the organization’s operations and financial results. Examples include a disposal of a major geographic area, a major line of business, or a major equity method investment. Additionally, the new guidance requires expanded disclosures about discontinued operations that will provide financial statement users with more information about the assets, liabilities, income, expenses of discontinued operations and of the pre-tax income attributable to a disposal of a significant part of an organization that does not qualify for discontinued operations reporting. The new guidance is effective for Agilent prospectively for all disposals (or classifications as held for sale) of components of an entity that occur after November 1, 2016.

	The disclosure of Keysight meets the definition of a discontinued operation under both the existing and amended accounting guidance.

	In January 2015 FASB issued guidance on simplifying income statement presentation by eliminating the concept of extraordinary items from U.S. GAAP. The amendments in this update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. A reporting entity may apply the amendments prospectively and retrospectively to all periods presented in the financial statements. Early adoption is permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. We have evaluated the accounting guidance and determined that there is no impact of this update to our consolidated financial statements.

	In February 2015, FASB issued an amendment to the analysis that a reporting entity must perform to determine whether it should consolidate certain types of legal entities. All legal entities are subject to reevaluation under the revised consolidation model. The amendments in this update are effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015. We are evaluating the impact of adopting this guidance to our consolidated financial statements.

	Other amendments to GAAP in the U.S. that have been issued by the FASB or other standards-setting bodies that do not require adoption until a future date are not expected to have a material impact on our consolidated financial statements upon adoption.

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations Disclosure	3. DISCONTINUED OPERATIONS

	On September 19, 2013, Agilent announced its intention to separate its electronic measurement business, Keysight, which was previously a separate reportable segment, into a stand-alone publicly traded company. Keysight was incorporated in Delaware as a wholly-owned subsidiary of Agilent on December 6, 2013. On November 1, 2014, we completed the distribution of 100% of the outstanding common stock of Keysight to Agilent stockholders, who received one share of Keysight common stock for every two shares of Agilent common stock held as of the close of business on the record date, October 22, 2014. The separation agreement ensures that Keysight had approximately $700 million of total cash immediately following distribution.

	The historical results of operations and statement of financial position of Keysight have been presented as discontinued operations in the condensed consolidated financial statements and prior periods have been restated. Discontinued operations include results of Keysight's business except for certain allocated corporate overhead costs and certain costs associated with transition services provided by Agilent to Keysight. Discontinued operations also includes other costs incurred by Agilent to separate Keysight. These costs include transaction charges, advisory and consulting fees and information system expenses.

	The following table summarizes results from discontinued operations of Keysight included in the condensed consolidated statement of operations:



		Three Months Ended

	Provision (benefit) for income taxes	(2		)	20

	Net income (loss) from discontinued operations	$	(30	)	$	74


	Net income (loss) from discontinued operations includes transaction, information systems and other costs to effect the separation of $32 million and $18 million for the three months ended January 31, 2015 and 2014, respectively. In the three months ended January 31, 2015 only those costs incurred to effect the separation have been included. No income or expense has been recorded for the Keysight business after separation from Agilent on November 1, 2014.

	The following table presents Agilent's electronic measurement business assets and liabilities removed from the condensed consolidated balance sheet as of November 1, 2014 and presented as discontinued operations as of October 31, 2014:

In addition, $332 million of accumulated other comprehensive loss, net of income taxes, primarily related to pension and other postretirement benefits plans and currency translation was also transferred to Keysight together with $28 million of additional paid in capital related to share based compensation windfall tax benefits. The removal of Keysight net assets and equity related adjustments is presented as a reduction in Agilent's retained earnings and represents a non cash financing activity excluding cash transferred. As of January 31, 2015, the net receivable balance due to Agilent from Keysight was $62 million related to excess cash and other pre-separation receivables per the Separation and Distribution Agreement and is included within the balance sheet of Agilent continuing operations. Excess cash represents the amount by which Agilent over-funded Keysight at distribution and is repayable to Agilent in accordance with the Separation and Distribution Agreement. In February 2015, substantially all balances due to Agilent have been settled by Keysight. See Note 5 “Income Taxes” for tax implications of the distribution and Note 4 “Share Based Compensation” for changes to share based compensation awards as a result of the distribution of Keysight.

In order to effect the separation and govern our relationship with Keysight after the separation, we entered into a Separation and Distribution Agreement and other agreements including a Tax Matters Agreement, an Employee Matters Agreement and a Transition Services Agreement. The Separation and Distribution Agreement governs the separation of the electronic measurement business, the transfer of assets and other matters related to our relationship with Keysight.

The Tax Matters Agreement governs the respective rights, responsibilities and obligations of Keysight and Agilent with respect to taxes, tax attributes, tax returns, tax proceedings and certain other tax matters.

The Employee Matters Agreement governs the compensation and employee benefit obligations with respect to the current and former employees and non-employee directors of Keysight and Agilent, and generally allocates liabilities and responsibilities relating to employee compensation, benefit plans and programs. The Employee Matters Agreement provides that employees of Keysight will no longer participate in benefit plans sponsored or maintained by Agilent. In addition, the Employee Matters Agreement provides that each of the parties will be responsible for their respective former and current employees and compensation plans for such current employees.

Under the terms of the Transition Services Agreement, we agreed to provide administrative, site services, information technology systems and various other corporate and support services to Keysight over the period of 12-18 months after the separation on a cost or cost-plus basis. The most significant component of the service income is the provision of IT services which we anticipate will be largely completed by the end of the second quarter of 2015. In total we expect to receive income for all services provided to Keysight of approximately $12 million. In addition, Agilent expects to receive lease income from Keysight over the next 4-5 years of approximately $13 million per year. In the three months ended January 31, 2015 other income (expense), net includes $11 million of income in respect of the provision of services to, and lease income from, Keysight.

	At January 31, 2015 and October 31, 2014, there was no share-based compensation capitalized within inventory. For the three months ended January 31, 2015 and 2014, the windfall tax benefit realized from exercised stock options and similar awards was zero and $3 million, respectively.

	The following assumptions were used to estimate the fair value of the options and LTPP grants.

	Price-wise correlation with selected peers	37	%	47	%

	In connection with the separation of Keysight on November 1, 2014 and in accordance with the Employee Matters Agreement we made certain adjustments to the exercise price and number of our share-based compensation awards with the intention of preserving the intrinsic value of the awards prior to the separation. Exercisable and non-exercisable stock options converted to those of the entity where the employee is working post-separation. Restricted stock units awards and long-term performance plan grants were adjusted to provide holders restricted stock units and long-term performance plan grants in the company that employs such employee following the separation. These adjustments to our stock-based compensation awards did not have a material impact on compensation expense.

	The fair value of share-based awards for employee stock option awards was estimated using the Black-Scholes option pricing model. Shares granted under the LTPP were valued using a Monte Carlo simulation model. Both the Black-Scholes and Monte Carlo simulation fair value models require the use of highly subjective and complex assumptions, including the option’s expected life and the price volatility of the underlying stock. Due to the separation of Keysight on November 1, 2014, expected volatility for grants of options in fiscal 2015 was based on a 5.5 year average historical stock price volatility of a group of our peer companies. For the volatility of our 2015 LTPP grants, we used the 3 year average historical stock price volatility of a group of our peer companies. We believe our historical volatility prior to the separation of Keysight is no longer relevant to use. For the grants of options and LTPP prior to November 1, 2014, the expected stock price volatility assumption was determined using the historical volatility of Agilent’s stock over the most recent historical period equivalent to the expected life of the stock options and LTPP.

	In developing our estimated life of our employees' stock options of 5.5 years, we considered the separation of Keysight and the historical option exercise behavior for our executive employees who were granted the majority of the options in the annual grants made which we believe is representative of future behavior.

	The estimated fair value of restricted stock unit awards is determined based on the market price of Agilent’s common stock on the date of grant adjusted for expected dividend yield. The ESPP allows eligible employees to purchase shares of our common stock at 85 percent of the purchase price and uses the purchase date to establish the fair market value.

INCOME TAXES	5. INCOME TAXES

	The company’s effective tax rate from continuing operations was 9.3 percent and (24.7) percent for the three months ended January 31, 2015 and 2014, respectively. The income tax expense was $11 million for the three months ended January 31, 2015 and an income tax benefit of $24 million for the three months ended January 31, 2014.

	The income tax provision from continuing operations for the three months ended January 31, 2015 included a net discrete tax benefit of $12 million. Current period items included in this total are $6 million of tax benefit for the extension, which occurred in the first quarter of 2015, of the U.S. research and development tax credit attributable to the company's prior fiscal year, and $3 million of other discrete tax expense items. In addition, the net discrete benefit included out of period adjustments for a $13 million tax benefit related to a tax rate change in Denmark and $4 million of tax expense attributable to an error discovered on a prior year U.S. tax return. These corrections are not considered to be material to current or prior periods. The income tax provision for the three months ended January 31, 2014 included a net discrete benefit of $50 million due to the settlement of an Internal Revenue Service ("IRS") audit in the U.S. offset by the recognition of tax expense related to the repatriation of dividends to the U.S.

	On November 1, 2014, Agilent transferred deferred tax assets of $238 million, deferred tax liabilities of $37 million, current income tax payable of $40 million, and other long-term liabilities related to uncertain tax positions totaling $8 million to Keysight as part of its separation from Agilent. A current prepaid income tax asset of $19 million and long-term prepaid income tax asset of $3 million related to sales of intercompany assets was also transferred to Keysight upon separation from Agilent.

	In the U.S., tax years remain open back to the year 2008 for federal income tax purposes and the year 2000 for significant states. On January 29, 2014 we reached an agreement with the IRS for the tax years 2006 through 2007. The settlement resulted in the recognition, within the continuing operations, of previously unrecognized tax benefits of $111 million, offset by a tax liability on foreign distributions of approximately $61 million principally related to additional foreign earnings that were recognized in conjunction with the settlement. Agilent's U.S. federal income tax returns for 2008 through 2011 are currently under audit by the IRS.

	In connection with the settlement of the 2006-2007 IRS audit, we identified during the first quarter of fiscal year 2014 an overstatement of approximately $65 million in our long-term tax liabilities. The overstatement was recorded in 2008 as a cumulative effect of a change in accounting principle when we adopted Accounting Standard Codification 740-10, Income Taxes. Accordingly, we corrected the error by reducing long-term tax liabilities and increasing retained earnings by $65 million in the first quarter of fiscal 2014. The correction had no impact on net income or cash flows in any prior period and is not considered material to total liabilities or equity in any prior period.

	In other major jurisdictions where the company conducts business, the tax years generally remain open back to the year 2003. With these jurisdictions and the U.S., it is reasonably possible that there could be significant changes to our unrecognized tax benefits in the next twelve months due to either the expiration of a statute of limitation or a tax audit settlement. Given the number of years and numerous matters that remain subject to examination in various tax jurisdictions, management is unable to estimate the range of possible changes to the balance of our unrecognized tax benefits.

	In connection with the separation of Keysight on November 1, 2014 and in accordance with the Employee Matters Agreement we made certain adjustments to the exercise price and number of our share-based compensation awards with the intention of preserving the intrinsic value of the awards prior to the separation. Exercisable and non-exercisable stock options, restricted stock grants, and long-term performance plan grants were converted to those of the entity where the employee is working post-separation and were adjusted to retain the intrinsic value of the awards prior to separation. These adjustments to our share-based awards did not have a material impact on our dilutive weighted average shares.

	The dilutive effect of share-based awards is reflected in diluted net income per share by application of the treasury stock method, which includes consideration of unamortized share-based compensation expense, the tax benefits or shortfalls recorded to additional paid-in capital and the dilutive effect of in-the-money options and non-vested restricted stock units. Under the treasury stock method, the amount the employee must pay for exercising stock options and unamortized share-based compensation expense and tax benefits or shortfalls collectively are assumed proceeds to be used to repurchase hypothetical shares. An increase in the fair market value of the company's common stock can result in a greater dilutive effect from potentially dilutive awards.

	We exclude stock options with exercise prices greater than the average market price of our common stock from the calculation of diluted earnings per share because their effect would be anti-dilutive. For the three months ended January 31, 2015 and 2014, 1.3 million options and zero options to purchase shares were excluded from the calculation of diluted earnings per share, respectively. In addition, we also exclude from the calculation of diluted earnings per share, stock options, ESPP, LTPP and restricted stock awards whose combined exercise price, unamortized fair value and excess tax benefits or shortfalls collectively were greater than the average market price of our common stock because their effect would also be anti-dilutive. For the three months ended January 31, 2015 and 2014, no additional options to purchase shares were excluded from the calculation of diluted earnings per share.

	During the three months ended January 31, 2014, there were no additions to goodwill or to other intangible assets. We also transferred $4 million from in-process R&D to purchased technology in the three months ended January 31, 2014, as projects were completed.

	Amortization of intangible assets was $43 million and $49 million for the three months ended January 31, 2015 and 2014, respectively. Future amortization expense related to existing finite-lived purchased intangible assets is estimated to be $115 million for the remainder of 2015, $133 million for 2016, $93 million for 2017, $61 million for 2018, $46 million for 2019, $36 million for 2020, and $56 million thereafter.

FAIR_VALUE_MEASUREMENTS

FAIR VALUE MEASUREMENTS	3 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	9. FAIR VALUE MEASUREMENTS

	The authoritative guidance defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, we consider the principal or most advantageous market and assumptions that market participants would use when pricing the asset or liability.

	Fair Value Hierarchy

	The guidance establishes a fair value hierarchy that prioritizes the use of inputs used in valuation techniques into three levels. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. There are three levels of inputs that may be used to measure fair value:

	Level 1- applies to assets or liabilities for which there are quoted prices in active markets for identical assets or liabilities.

	Level 2- applies to assets or liabilities for which there are inputs other than quoted prices included within level 1 that are observable, either directly or indirectly, for the asset or liability such as: quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in less active markets; or other inputs that can be derived principally from, or corroborated by, observable market data.

	Level 3- applies to assets or liabilities for which there are unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the assets or liabilities.

	Financial Assets and Liabilities Measured at Fair Value on a Recurring Basis

	Financial assets and liabilities measured at fair value on a recurring basis as of January 31, 2015 were as follows:



					Fair Value Measurement at January 31, 2015 Using

Our money market funds and trading securities investments are generally valued using quoted market prices and therefore are classified within level 1 of the fair value hierarchy. Our derivative financial instruments are classified within level 2, as there is not an active market for each hedge contract, but the inputs used to calculate the value of the instruments are tied to active markets. Our deferred compensation liability is classified as level 2 because, although the values are not directly based on quoted market prices, the inputs used in the calculations are observable.

Trading securities and deferred compensation liability are reported at fair value, with gains or losses resulting from changes in fair value recognized currently in net income. Certain derivative instruments are reported at fair value, with unrealized gains and losses, net of tax, included in other comprehensive income.

Impairment of Investments. There were no impairments for investments for the three months ended January 31, 2015 and 2014.

Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis

For the three months ended January 31, 2015 and 2014, there were no impairments of long-lived assets held and used. For the three months ended January 31, 2015 and 2014, there were no impairments of long-lived assets held for sale.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVES	10. DERIVATIVES

	We are exposed to foreign currency exchange rate fluctuations and interest rate changes in the normal course of our business. As part of risk management strategy, we use derivative instruments, primarily forward contracts, purchased options to hedge economic and/or accounting exposures resulting from changes in foreign currency exchange rates.

	Fair Value Hedges

	We are exposed to interest rate risk due to the mismatch between the interest expense we pay on our loans at fixed rates and the variable rates of interest we receive from cash, cash equivalents and other short-term investments. We have issued long-term debt in U.S. dollars at fixed interest rates based on the market conditions at the time of financing. The fair value of our fixed rate debt changes when the underlying market rates of interest change, and, in the past, we have used interest rate swaps to change our fixed interest rate payments to U.S. dollar LIBOR-based variable interest expense to match the floating interest income from our cash, cash equivalents and other short term investments. As of January 31, 2015, all interest rate swap contracts had either been terminated or had expired.

	On November 25, 2008, we terminated two interest rate swap contracts associated with our 2017 senior notes that represented the notional amount of $400 million. On October 20, 2014 we prepaid $500 million out of $600 million principal of our 2017 senior notes and fully amortized the associated proportionate deferred gain to other income (expense). The remaining gain to be amortized related to the $100 million of 2017 senior notes at January 31, 2015 was $2 million. On August 9, 2011, we terminated five interest rate swap contracts related to our 2020 senior notes that represented the notional amount of $500 million. The gain to be amortized at January 31, 2015 was $21 million. All deferred gains from terminated interest rate swaps are being amortized over the remaining life of the respective senior notes.

	Cash Flow Hedges

	We enter into foreign exchange contracts to hedge our forecasted operational cash flow exposures resulting from changes in foreign currency exchange rates. These foreign exchange contracts, carried at fair value, have maturities between one and twelve months. These derivative instruments are designated and qualify as cash flow hedges under the criteria prescribed in the authoritative guidance. The changes in fair value of the effective portion of the derivative instrument are recognized in accumulated other comprehensive income. Amounts associated with cash flow hedges are reclassified to cost of sales in the condensed consolidated statement of operations when the forecasted transaction occurs. If it becomes probable that the forecasted transaction will not occur, the hedge relationship will be de-designated and amounts accumulated in other comprehensive income will be reclassified to other income (expense) in the current period. Changes in the fair value of the ineffective portion of derivative instruments are recognized in other income (expense) in the condensed consolidated statement of operations in the current period. We record the premium paid (time value) of an option on the date of purchase as an asset. For options designated as cash flow hedges, changes in the time value are excluded from the assessment of hedge effectiveness and are recognized in other income (expense) over the life of the option contract. Ineffectiveness in the three months ended January 31, 2015 and 2014 was not significant. For the three months ended January 31, 2015 and 2014 gains and losses recognized in other income (expense) due to de-designation of cash flow hedge contracts were not significant.

	In July 2012, Agilent executed treasury lock agreements for $400 million in connection with future interest payments to be made on our 2022 senior notes issued on September 10, 2012. We designated the treasury lock as a cash flow hedge. The treasury lock contracts were terminated on September 10, 2012 and we recognized a deferred gain in accumulated other comprehensive income of $3 million which is being amortized to interest expense over the life of the 2022 senior notes.

	Other Hedges

	Additionally, we enter into foreign exchange contracts to hedge monetary assets and liabilities that are denominated in currencies other than the functional currency of our subsidiaries. These foreign exchange contracts are carried at fair value and do not qualify for hedge accounting treatment and are not designated as hedging instruments. Changes in value of the derivative are recognized in other income (expense) in the condensed consolidated statement of operations, in the current period, along with the offsetting foreign currency gain or loss on the underlying assets or liabilities.

	Our use of derivative instruments exposes us to credit risk to the extent that the counterparties may be unable to meet the terms of the agreement. We do, however, seek to mitigate such risks by limiting our counterparties to major financial institutions which are selected based on their credit ratings and other factors. We have established policies and procedures for mitigating credit risk that include establishing counterparty credit limits, monitoring credit exposures, and continually assessing the creditworthiness of counterparties.

	A number of our derivative agreements contain threshold limits to the net liability position with counterparties and are dependent on our corporate credit rating determined by the major credit rating agencies. The counterparties to the derivative instruments may request collateralization, in accordance with derivative agreements, on derivative instruments in net liability positions.

	The aggregate fair value of all derivative instruments with credit-risk-related contingent features that were in a net liability position as of January 31, 2015, was $6 million. The credit-risk-related contingent features underlying these agreements had not been triggered as of January 31, 2015.

	There were 53 foreign exchange forward contracts and 3 foreign exchange option contracts open as of January 31, 2015 and designated as cash flow hedges. There were 160 foreign exchange forward contracts open as of January 31, 2015 not designated as hedging instruments.

Restructuring and Related Activities Disclosure [Text Block]	11. EXIT OF NMR BUSINESS

	During the fourth quarter of fiscal year 2014, we made the decision to cease the manufacture and sale of our NMR product line within our life sciences and applied markets segment. The exit of the NMR business was primarily due to the lack of growth and profitability of the product line. These actions involved severance and other personnel costs related to the workforce reduction of approximately 300 employees primarily located in the United Kingdom and California and non-cash charges related to intangible asset impairments and other asset write-downs including inventory. We expect to substantially complete these restructuring activities by the end of fiscal 2016. As of January 31, 2015, approximately 200 employees are pending termination under the above actions.

	A summary of total “NMR” restructuring activity and other special charges is shown in the table below:

	Plan Amendments. Effective November 1, 2014, Agilent’s U.S. defined benefit retirement plan closed to new entrants including new employees, new transfers to the U.S. payroll and rehires. These employees are instead eligible for an enhanced 6 percent employer match in the Agilent 401(k) plan. In addition, any new employee hired on or after November 1, 2014, is not eligible to participate in the retiree medical plans upon retiring. Current eligible employees will continue to participate in the U.S. defined benefit retirement plan and retiree medical programs in place today and will remain eligible for the 401(k) plan with the current 4 percent employer match. Retirees will maintain the retirement benefits and retiree medical benefits they are eligible for today.

	Warranties

	We accrue for standard warranty costs based on historical trends in warranty charges as a percentage of net product shipments. The accrual is reviewed regularly and periodically adjusted to reflect changes in warranty cost estimates. Estimated warranty charges are recorded within cost of products at the time products are sold. The standard warranty accrual balances are held in other accrued and other long-term liabilities on our condensed consolidated balance sheet. Our standard warranty terms typically extend to one year from the date of delivery, depending on the product.

	A summary of the standard warranty accrual activity is shown in the table below:

	Stock Repurchase Program

	On November 22, 2013 we announced that our board of directors had authorized a new share repurchase program effective in the first quarter of fiscal year 2014, upon the conclusion of the company's $1 billion repurchase program. The new program is designed to reduce or eliminate dilution resulting from issuance of stock under the company's employee equity incentive programs to target maintaining a weighted average share count of approximately 335 million diluted shares.

	For the three months ended January 31, 2015, we repurchased 158 thousand shares for $6 million. For the three months ended January 31, 2014, 2 million shares were repurchased for $100 million. All such shares and related costs are held as treasury stock and accounted for using the cost method.

	Cash Dividends on Shares of Common Stock

	During the three months ended January 31, 2015, we paid cash dividends of $0.100 per common share or $34 million on the company's common stock. During the three months ended January 31, 2014, we paid cash dividends of $0.132 per common share or $44 million on the company's common stock.

SEGMENT_INFORMATION

Segment Reporting [Abstract]
SEGMENT INFORMATION	17. SEGMENT INFORMATION

	Description of segments. We are a global leader in life sciences, diagnostics and applied chemical markets, providing application focused solutions that include instruments, software, services and consumables for the entire laboratory workflow. In the first fiscal quarter of 2015, we completed the separation of our electronic measurement business. See Note 3 "Discontinued Operations" for further information.
	In November 2014, we announced a change in organizational structure designed to better serve our customers. Our new structure reflects our strategy to focus our expertise on the market segments we serve and utilize our resources to offer product solutions to address our customer needs. The new operating structure ensures that we are able to respond to market demand while reducing costs through increased efficiencies. As a result, our life sciences business, excluding the nucleic acid solutions division, together with the chemical analysis business merged to form a new segment called life sciences and applied markets business. Our diagnostics and genomics businesses combined and includes the nucleic acid solutions division of our life sciences business and became the diagnostics and genomics segment. Finally, the Agilent CrossLab segment was formed from the services and consumables businesses. The historical financial segment information has been recast to conform to this new presentation.
	Following this reorganization, Agilent has three business segments comprised of the life sciences and applied markets business, diagnostics and genomics business and the Agilent CrossLab business each of which comprises a reportable segment. The three operating segments were determined based primarily on how the chief operating decision maker views and evaluates our operations. Operating results are regularly reviewed by the chief operating decision maker to make decisions about resources to be allocated to the segment and to assess its performance. Other factors, including market separation and customer specific applications, go-to-market channels, products and services and manufacturing are considered in determining the formation of these operating segments.
	A description of our three reportable segments is as follows:
	Our life sciences and applied markets business provides application-focused solutions that include instruments and software that enable customers to identify, quantify and analyze the physical and biological properties of substances and products, as well as enable customers in the clinical and life sciences research areas to interrogate samples at the molecular level. Key product categories include: liquid chromatography ("LC") systems and components; liquid chromatography mass spectrometry ("LCMS") systems; gas chromatography ("GC") systems and components; gas chromatography mass spectrometry ("GCMS") systems; inductively coupled plasma mass spectrometry ("ICP-MS") instruments; atomic absorption ("AA") instruments; microwave plasma-atomic emission spectrometry (“MP-AES”) instruments; inductively coupled plasma optical emission spectrometry ("ICP-OES") instruments; laboratory software and informatics systems; laboratory automation and robotic systems; dissolution testing; X-Ray Diffraction systems; vacuum pumps and measurement technologies.
	Our diagnostics and genomics business is comprised of three areas of activity providing solutions that include reagents, instruments, software and consumables that enable customers in the clinical and life sciences research areas to interrogate samples at the cellular and molecular level. First, the former Dako business is focused on product offerings to cancer diagnostics and anatomic pathology workflows. The broad portfolio of offerings includes immunohistochemistry (“IHC”), In Situ Hybridization (“ISH”), Hematoxylin and Eosin (“H&E”) staining and special staining. We also collaborate with a number of major pharmaceutical companies to develop new potential pharmacodiagnostics, also known as companion diagnostics, which may be used to identify patients most likely to benefit from a specific targeted therapy. Secondly our genomics business includes arrays for DNA mutation detection, genotyping, gene copy number determination, identification of gene rearrangements, DNA methylation profiling, gene expression profiling, as well as NGS target enrichment. Finally our nucleic acid solutions business provides equipment and expertise focused on production of synthesized oligonucleotides under pharmaceutical GMP conditions for use as APIs (Active Pharmaceutical Ingredients) in an emerging class of drugs that utilize nucleic acid molecules for disease therapy.

	The Agilent CrossLab business spans the entire lab with its extensive consumables and services portfolio, which is designed to improve customer outcomes. The majority of the portfolio is vendor neutral, meaning Agilent can serve and supply customers regardless of their instrument purchase choices. Solutions range from chemistries and supplies to services and software helping to connect the entire lab. Key product categories in consumables include GC and LC columns, sample preparation products, custom chemistries, and a large selection of laboratory instrument supplies. Services include startup, operational, training and compliance support, as well as asset management and consultative services that help increase customer productivity. Custom service and consumable bundles are tailored to meet the specific application needs of various industries and to keep instruments fully operational and compliant with the respective industry requirements.

	A significant portion of the segments' expenses arise from shared services and infrastructure that we have historically provided to the segments in order to realize economies of scale and to efficiently use resources. These expenses, collectively called corporate charges, include legal, accounting, real estate, insurance services, information technology services, treasury, other corporate infrastructure expenses and costs of centralized research and development. Charges are allocated to the segments, and the allocations have been determined on a basis that we consider to be a reasonable reflection of the utilization of services provided to or benefits received by the segments. Corporate charges previously allocated to our electronic measurement business, but not classified within discontinued operations, were not reallocated to our other segments. These charges are presented below as a component of the reconciliation between segments' income from operations and Agilent's income from continuing operations and are classified as unallocated corporate charges. In addition, we do not allocate amortization and impairment of acquisition-related intangible assets, restructuring and transformational expenses, acquisition and integration costs and certain other charges to the operating margin for each segment because management does not include this information in its measurement of the performance of the operating segments.

	The following tables reflect the results of our reportable segments under our management reporting system. These results are not necessarily in conformity with U.S. GAAP. The performance of each segment is measured based on several metrics, including adjusted income from operations. These results are used, in part, by the chief operating decision maker in evaluating the performance of, and in allocating resources to, each of the segments.

	The profitability of each of the segments is measured after excluding restructuring and asset impairment charges, investment gains and losses, interest income, interest expense, acquisition and integration costs, non-cash amortization and other items as noted in the reconciliations below.

OVERVIEW_BASIS_OF_PRESENTATION1

OVERVIEW, BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	3 Months Ended
	Jan. 31, 2015
Accounting Policies [Abstract]
Overview, Segment Structure and Basis of Presentation	Overview. Agilent Technologies Inc. ("we", "Agilent" or the "company"), incorporated in Delaware in May 1999, is a global leader in life sciences, diagnostics and applied chemical markets, providing application focused solutions that includes instruments, software, services and consumables for the entire laboratory workflow.

	Our fiscal year-end is October 31, and our fiscal quarters end on January 31, April 30 and July 31. Unless otherwise stated, these dates refer to our fiscal year and fiscal quarters.

	Keysight Separation. On November 1, 2014, we completed the distribution of 100% of the outstanding common shares of Keysight Technologies, Inc. ("Keysight") to Agilent stockholders who received one share of Keysight common stock for every two shares of Agilent held as of the close of business on the record date, October 22, 2014. The historical results of operations and the financial position of Keysight are included in the consolidated financial statements of Agilent and are reported as discontinued operations within this Form 10-Q. See "Basis of Presentation".

	New Segment Structure. In November 2014, we announced a change in organizational structure designed to better serve our customers. Our life sciences business, excluding the nucleic acid solutions division, together with the chemical analysis business combined to form a new segment called life sciences and applied markets business. Our diagnostics and genomics businesses combined with the nucleic acid solutions division from our life sciences business and became the diagnostics and genomics segment. Finally, the Agilent CrossLab segment was formed from the services and consumables businesses previously part of the life sciences and chemicals analysis businesses. Financial reporting under this new structure is included within this report on Form 10-Q and historical financial segment information has been recast to conform to this new presentation within our financial statements.

	Basis of Presentation. We have prepared the accompanying financial data for the three months ended January 31, 2015 and 2014 pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles (“GAAP”) in the U.S. have been condensed or omitted pursuant to such rules and regulations. The accompanying financial data and information should be read in conjunction with our Annual Report on Form 10-K.

	In the opinion of management, the accompanying condensed consolidated financial statements contain all normal and recurring adjustments necessary to present fairly our condensed consolidated balance sheet as of January 31, 2015 and October 31, 2014, condensed consolidated statement of comprehensive income for the three months ended January 31, 2015 and 2014, condensed consolidated statement of operations for the three months ended January 31, 2015 and 2014, and condensed consolidated statement of cash flows for the three months ended January 31, 2015 and 2014.

	The prior year results of operations and the prior year end financial position of Keysight are included in the consolidated financial statements of Agilent and reported as discontinued operations. The prior year statement of comprehensive income and prior year statement of cash flows have not been adjusted to reflect the effect of the separation of Keysight. Unless indicated otherwise, the information in the Notes to the condensed consolidated financial statements relates to our continuing operations.
Use of Estimates	Use of estimates. The preparation of condensed consolidated financial statements in accordance with GAAP in the U.S. requires management to make estimates and assumptions that affect the amounts reported in our condensed consolidated financial statements and accompanying notes. Management bases its estimates on historical experience and various other assumptions believed to be reasonable. Although these estimates are based on management’s best knowledge of current events and actions that may impact the company in the future, actual results may be different from the estimates. Our critical accounting policies are those that affect our financial statements materially and involve difficult, subjective or complex judgments by management. Those policies are revenue recognition, valuation of goodwill and purchased intangible assets, inventory valuation, share-based compensation, retirement and post-retirement plan assumptions, restructuring and accounting for income taxes.
Update to Share-based Compensation Policy	Update to Significant Accounting Policies. For the stock option and long term performance plan grants in 2015 we are now using a volatility measure derived from a selection of our peer companies. In prior periods, we used Agilent stock historical volatility. We now consider this method to not be reflective of our future volatility due to the separation of Keysight. See Note 4, "Share-based compensation" for additional information. There have been no other material changes to our significant accounting policies, as compared to the significant accounting policies described in our Annual Report on Form 10-K for the fiscal year ended October 31, 2014.
Fair Value of Financial Instruments	Fair Value of Financial Instruments. The carrying values of certain of our financial instruments including cash and cash equivalents, accounts receivable, accounts payable, accrued compensation and other accrued liabilities approximate fair value because of their short maturities. The fair value of long-term equity investments is determined using quoted market prices for those securities when available. For those long-term equity investments accounted for under the cost or equity method, their carrying value approximates their estimated fair value. Equity method investments are reported at the amount of the company’s initial investment and adjusted each period for the company’s share of the investee’s income or loss and dividend paid. The fair value of our long-term debt, calculated from quoted prices which are primarily Level 1 inputs under the accounting guidance fair value hierarchy, exceeds the carrying value by approximately $45 million and $53 million as of January 31, 2015 and October 31, 2014, respectively. The fair value of foreign currency contracts used for hedging purposes is estimated internally by using inputs tied to active markets. These inputs, for example, interest rate yield curves, foreign exchange rates, and forward and spot prices for currencies are observable in the market or can be corroborated by observable market data for substantially the full term of the assets or liabilities. See also Note 9, "Fair Value Measurements" for additional information on the fair value of financial instruments.
Fair Value of Financial Instruments
Goodwill and Purchased Intangible Assets	Goodwill and Purchased Intangible Assets. Under the authoritative guidance we have the option to perform a qualitative assessment to determine whether further impairment testing is necessary. The accounting standard gives an entity the option to first assess qualitative factors to determine whether performing the two-step test is necessary. If an entity believes, as a result of its qualitative assessment, that it is more-likely-than-not (i.e. greater than 50% chance) that the fair value of a reporting unit is less than its carrying amount, the quantitative impairment test will be required. Otherwise, no further testing will be required.

	The guidance includes examples of events and circumstances that might indicate that a reporting unit's fair value is less than its carrying amount. These include macro-economic conditions such as deterioration in the entity's operating environment or industry or market considerations; entity-specific events such as increasing costs, declining financial performance, or loss of key personnel; or other events such as an expectation that a reporting unit will be sold or a sustained decrease in the stock price on either an absolute basis or relative to peers.

	If it is determined, as a result of the qualitative assessment, that it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount, the provisions of authoritative guidance require that we perform a two-step impairment test on goodwill. In the first step, we compare the fair value of each reporting unit to its carrying value. The second step (if necessary) measures the amount of impairment by applying fair-value-based tests to the individual assets and liabilities within each reporting unit. As defined in the authoritative guidance, a reporting unit is an operating segment, or one level below an operating segment. We aggregate components of an operating segment that have similar economic characteristics into our reporting units.

	In fiscal year 2014, we assessed goodwill impairment for three reporting units under our previous reporting structure which consisted of one segment: chemical analysis and two reporting units under the life sciences and diagnostics segment. The first of these two reporting units related to our life sciences business and the second related to our diagnostics business. We performed a qualitative test for goodwill impairment of our previous three reporting units as of September 30, 2014. Based on the results of our qualitative testing, we believe that it is more-likely-than-not that the fair value of these reporting units are greater than their respective carrying values. Each quarter we review the events and circumstances to determine if goodwill impairment is indicated. In connection with our annual goodwill impairment testing in 2015, we will assess for potential impairment of goodwill on our new reporting units resulting from our reorganization. In the three months ended January 31, 2015 and 2014, there was no triggering event that would indicate that there was an impairment of goodwill therefore there was no impairment of goodwill during the three months ended January 31, 2015 and 2014.

	Purchased intangible assets consist primarily of acquired developed technologies, proprietary know-how, trademarks, and customer relationships and are amortized using the best estimate of the asset's useful life that reflect the pattern in which the economic benefits are consumed or used up or a straight-line method ranging from 6 months to 15 years. In-process research and development ("IPR&D") is initially capitalized at fair value as an intangible asset with an indefinite life and assessed for impairment thereafter. When the IPR&D project is complete, it is reclassified as an amortizable purchased intangible asset and is amortized over its estimated useful life. If an IPR&D project is abandoned, Agilent will record a charge for the value of the related intangible asset to Agilent's condensed consolidated statement of operations in the period it is abandoned.

	Agilent's indefinite-lived intangible assets are IPR&D intangible assets. The accounting guidance allows a qualitative approach for testing indefinite-lived intangible assets for impairment, similar to the issued impairment testing guidance for goodwill and allows the option to first assess qualitative factors (events and circumstances) that could have affected the significant inputs used in determining the fair value of the indefinite-lived intangible asset to determine whether it is more-likely-than-not (i.e. greater than 50% chance) that the indefinite-lived intangible asset is impaired. An organization may choose to bypass the qualitative assessment for any indefinite-lived intangible asset in any period and proceed directly to calculating its fair value. We performed a qualitative test for impairment of indefinite-lived intangible assets as of September 30, 2014. Based on the results of our qualitative testing, we believe that it is more-likely-than-not that the fair value of these indefinite-lived intangible assets is greater than their respective carrying values. Each quarter we review the events and circumstances to determine if impairment of indefinite-lived intangible asset is indicated. There was no impairment of indefinite-lived intangible asset during the three months ended January 31, 2015 and January 31, 2014.
