Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure	1. BASIS OF PRESENTATION AND USE OF ESTIMATES Basis of Presentation In this report, “Bio-Rad,” “we,” “us,” “the Company” and “our” refer to Bio-Rad Laboratories, Inc. and its subsidiaries. The accompanying unaudited condensed consolidated financial statements of Bio-Rad have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) and reflect all adjustments which are, in the opinion of management, necessary to fairly state the results of the interim periods presented. All such adjustments are of a normal recurring nature. Results for the interim period are not necessarily indicative of the results for the entire year. The condensed consolidated balance sheet at December 31, 2018 has been derived from the audited consolidated financial statements at that date but does not include all of the information and footnotes required by GAAP for complete financial statements. The condensed consolidated financial statements should be read in conjunction with the notes to the consolidated financial statements contained in our Annual Report on Form 10-K for the year ended December 31, 2018 . We evaluate subsequent events and the evidence they provide about conditions existing at the date of the balance sheet as well as conditions that arose after the balance sheet date but through the date the financial statements are issued. The effects of conditions that existed at the balance sheet date are recognized in the financial statements. Events and conditions arising after the balance sheet date but before the financial statements are issued are evaluated to determine if disclosure is required to keep the financial statements from being misleading. To the extent such events and conditions exist, disclosures are made regarding the nature of events and the estimated financial effects of those events and conditions. Use of Estimates The preparation of the condensed consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingencies at the date of the financial statements as well as the reported amounts of revenues and expenses during the reporting periods. Bio-Rad bases its estimates on historical experience and on various other market-specific and other relevant assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ materially from those estimates. Revenue Recognition On January 1, 2018, we adopted Accounting Standards Codification ("ASC") 606, "Revenue from Contracts with Customers," using the modified retrospective method applied to those contracts that were not completed as of January 1, 2018. We recorded a net reduction to opening retained earnings of $0.1 million as of January 1, 2018 due to the cumulative impact of adopting ASC 606 with the impact primarily related to a customer loyalty program in the United States for which the resulting non-cash consideration is treated as variable consideration under the new revenue recognition accounting standard. We recognize revenue from operations through the sale of products, services, and rental of instruments. Revenue from contracts with customers is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration we expect to receive in exchange for those products or services. We enter into contracts that can include various combinations of products and services, which are generally accounted for as distinct performance obligations. Revenue is recognized net of any taxes collected from customers (sales tax, value added tax, etc.), which are subsequently remitted to government authorities. Our contracts from customers often include promises to transfer multiple products and services to a customer. Determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment, and may or may not impact the timing of revenue recognition. Revenue associated with equipment that requires factory installation is not recorded until installation is complete and customer acceptance, if required, has occurred. Certain equipment requires installation due to the fact that the instruments are being operated in a clinical/laboratory environment, and the installation services could result in modification of the equipment in order to ensure that the instruments are working according to specifications of the customer which are subject to validation tests upon completion of the installation. In these arrangements, which require factory installation, the delivery of the equipment and the installation are separate performance obligations. We will recognize the transaction price allocated to the equipment only upon customer acceptance, as the transfer of control has occurred in relation to the equipment at that point in time as the customer has the ability to direct the use of and obtain substantially all of the remaining benefits from the asset. The transaction price allocated to the installation services is also recognized upon completion of the services because without the completion of the installation services and related customer acceptance the customer cannot receive any of the benefits of the service. At the time revenue is recognized, a provision is recognized for estimated product returns as this right is considered variable consideration. Accordingly, when product revenues are recognized, the transaction price is reduced to the estimated amount that we expect to receive in exchange for transferring control for those products. Service revenues on extended warranty contracts are recognized ratably over the life of the service agreement as a stand-ready performance obligation. For arrangements that include a combination of products and services, transaction prices are allocated to performance obligations based on stand-alone selling prices. The method used to determine the stand-alone selling prices for service revenues is based on the observable prices when the services have been sold separately. In those instances where the timing of revenue recognition differs from the timing of invoicing, we have determined that our contracts generally do not include a significant financing component. The primary purpose of our invoicing terms is to provide customers with simple and predictable methods of purchasing our products and services, not to either provide or receive financing to or from our customers. We record contract liabilities when cash payments are received or due in advance of our performance. We do not disclose the value of unsatisfied performance obligations for contracts with an original expected length of one year or less and for contracts in which we recognize revenue at the amount to which we have the right to invoice for services performed. Our payment terms vary by the type and location of our customer, and the products and services offered. The term between invoicing and when payment is due is not significant. Reagent Rental Agreements Reagent rental agreements are a diagnostic industry sales method that provides use of an instrument and consumables (reagents) to a customer on a per test basis. These agreements may also include maintenance of the underlying instruments retained at customer locations as well as initial training. We initially determine if a reagent rental arrangement contains a lease at lease commencement. Where we have determined that such an arrangement contains a lease, we next must ascertain its lease classification for purposes of applying appropriate accounting treatment as an operating, sales-type or direct financing lease. In addition, for purposes of determining the lease term used in performing the lease classification test, we include the noncancellable period of the lease together with those periods covered by the option to extend the lease if the customer is reasonably certain to exercise that option, the periods covered by an option to terminate the lease if the customer is reasonably certain not to exercise that option, and the periods covered by the option to extend (or not to terminate) the lease in which exercise of the option is controlled by the company. While most of our reagent rental arrangements contain either the option for a lessee to extend and/or cancel, the period in which the contract is enforceable is a very short period and therefore the lease term has been limited to the non-cancellable period. Furthermore, it has historically been very rare for these arrangements to contain an option for the lessee to purchase the underlying asset. As discussed further below under the captions “Leases” and “Recent Accounting Pronouncements Adopted,” as well as in Note 14, Leases, we adopted ASC 842, “Leases,” on a modified retrospective basis effective January 1, 2019 with practical expedients, and did not restate comparative prior periods. We concluded that the use of the instrument (referred to as “lease elements”) is not within the guidance of ASC 606 but rather ASC 842. Accordingly, we first allocate the transaction price between the lease elements and the non-lease elements based on relative standalone selling prices. The determination of the transaction price requires judgment and consideration of any fixed/minimum payments as well as estimates of variable consideration. After allocation, the amount of variable payments allocated to lease components will be recognized as income under ASC 842, while the amount of variable payments allocated to non-lease components will be recognized as income in accordance with ASC 606. Upon our adoption of ASC 842 in 2019, the maintenance services, along with the reagents, are now allocated to the non-lease elements and will be recognized as income in accordance with ASC 606. This change is in alignment with the requirements of ASC 842, and has resulted in a decrease in the amount of rental income that is included in our total revenue. Generally, the terms of the arrangements result in the transfer of control on reagents upon either (i) when the consumables are delivered or (ii) when the consumables are consumed by the customer. Historically, our reagent rental arrangements have been predominantly comprised of variable lease payments, as very few of such arrangements contain any fixed/minimum lease payments. As a result, our lease income is heavily variable in nature with only relatively insignificant amounts of lease income comprised of fixed or stated minimum lease payments. Further, our reagent rental arrangements are predominantly classified as operating leases, with only very insignificant lease income associated with sales-type leases. Hence, our reported lease income is primarily variable in nature and is recognized over time as the reagents are consumed by the customer or delivered. Revenue allocated to the lease elements of these reagent rental arrangements represents approximately 3% and 5% of total revenue in the first quarter of 2019 compared to the first quarter of 2018, respectively, and is included as part of Net sales in our Condensed Consolidated Statements of Income. Contract costs: As a practical expedient, we expense as incurred costs to obtain contracts as the amortization period would have been one year or less. These costs, recorded within Selling, general and administrative expense, include our internal sales force compensation programs and certain partner sales incentive programs, as we have determined that annual compensation is commensurate with annual selling activities. Disaggregation of Revenue: The following table presents our revenues disaggregated by geographic region based primarily on the location of the use of the product or service (in millions, unaudited): Three Months Ended March 31, 2019 2018 Europe $ 185.9 $ 199.6 Pacific Rim 106.4 109.4 United States 226.1 209.9 Other (primarily Canada and Latin America) 35.6 32.6 Total Net sales $ 554.0 $ 551.5 The disaggregation of our revenue by industry segment sources is presented in our Segment Information footnote (see Note 11). Deferred revenues represent mostly unrecognized fees billed or collected for extended service arrangements. Deferred revenues are generally recognized ratably over the term of the service contract as our performance extends over the life of the arrangement. A majority of our deferred revenue balance is classified as current with an expected length of one year or less. The increase in our total deferred revenue balance from $37.3 million at December 31, 2018 to $41.1 million at March 31, 2019 is primarily driven by $15.2 million , net, of cash payments received or due in advance of satisfying our performance obligations, partially offset by $11.4 million of revenue recognized that were included in our deferred revenue balance as of December 31, 2018 . We warrant certain equipment against defects in design, materials and workmanship, generally for a period of one year. Upon revenue recognition of that equipment, we establish, as part of Cost of goods sold, a provision for the expected costs of such warranty based on historical experience, specific warranty terms and customer feedback. A review is performed on a quarterly basis to assess the adequacy of our warranty accrual. Components of the warranty accrual, included in Other current liabilities and Other long-term liabilities in the Condensed Consolidated Balance Sheets, were as follows (in millions): December 31, 2018 $ 10.1 Provision for warranty 1.4 Actual warranty costs (2.2 ) March 31, 2019 $ 9.3 Leases We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, other current liabilities, and operating lease liabilities in our condensed consolidated balance sheet as of March 31, 2019. Finance leases are included in property, plant and equipment, other current liabilities, and other long-term liabilities in our condensed consolidated balance sheet as of March 31, 2019. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Where we act as lessee, we elected not to separate lease and non-lease components and are more fully described in Note 14, Leases. Where we act as lessor in our reagent rental arrangements, we allocate the consideration in the contract to the separate lease components and non-lease components. After allocation, the amount of variable payments allocated to lease components will be recognized as income under the lease accounting standard ASC 842, while the amount of variable payments allocated to non-lease components will be recognized as income in accordance with ASC 606. Such reagent rental arrangements are more fully described above under the caption "Reagent Rental Agreements." Recent Accounting Pronouncements and Securities and Exchange Commission ("SEC") Rule Adopted In August 2018, the FASB issued ASU 2018-15, "Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract." ASU 2018-15 amends the definition of a hosting arrangement and requires a customer in a hosting arrangement that is a service contract to capitalize certain implementation costs as if the arrangement was an internal-use software project. The internal-use software guidance states that only qualifying costs incurred during the application development stage can be capitalized. We prospectively adopted ASU 2018-15 effective January 1, 2019. During the first quarter of 2019, we capitalized $0.7 million of implementation costs for cloud computing arrangements, net of accumulated amortization, primarily for business analytics software, and is recorded in Other current assets and Other assets in the Condensed Consolidated Balance Sheet. In August 2018, the SEC issued Final Rule Release No. 33-10532, "Disclosure Update and Simplification" that extends to interim periods the annual disclosure requirement of presenting the changes in stockholder' equity, which was effective in the first quarter of 2019. In February 2016, the FASB issued ASU 2016-02, "Leases," and related accounting standard updates, which requires, among other items, lease accounting to recognize most leases as assets and liabilities on the balance sheet. Qualitative and quantitative disclosures are enhanced to better understand the amount, timing and uncertainty of cash flows arising from leases. We adopted ASU 2016-02 on a modified retrospective basis effective January 1, 2019 with practical expedients, and did not restate comparative prior periods. Where we act as a lessee, the adoption of the standard resulted in material additions to the balance sheet for right-of-use assets and the associated liabilities, see Note 14, Leases. The practical expedients include, among other items, for leases that existed prior January 1, 2019, to not reassess whether any contracts are or contain embedded leases, reassessing the classification of existing leases, and reassessing whether previously capitalized initial direct costs qualify for capitalization. Where we act as a lessee, we also elected not to separate lease and non-lease components. Where we act as a lessor in reagent rental arrangements, there was an insignificant impact to our condensed consolidated financial statements, which is more fully described above under the caption "Reagent Rental Agreements." Recent Accounting Pronouncements to be Adopted In November 2018, the FASB issued ASU 2018-18, "Clarifying the Interaction between Topic 808 and Topic 606." Topic 808 is Collaborative Arrangements, and Topic 606 is Revenue from Contracts with Customers. ASU 2018-18 clarifies that certain transactions between collaborative partners should be accounted for as revenue under ASC 606 when the collaborative partner is a customer. We currently do not have any customers that are collaborative partners or anticipate any in the near future. ASU 2018-18 will be effective January 1, 2020. In August 2018, the FASB issued ASU 2018-14, "Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans." ASU 2018-14 eliminates and adds certain disclosures for defined benefit plans. ASU 2018-14 is effective for fiscal years ending after December 15, 2020 using a retrospective approach. We are currently evaluating the disclosures but do not expect ASU 2018-14 to have a material impact to our disclosures for defined benefit plans. In August 2018, the FASB issued ASU 2018-13, "Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement." ASU 2018-13 eliminates, adds and modifies certain disclosures for fair value measurements. ASU 2018-13 is effective for fiscal years beginning after December 15, 2019 and for interim periods within those fiscal years. We do not expect ASU 2018-13 to have a material impact to our fair value disclosures.

Business Combinations [Abstract]
Business Combination Disclosure [Text Block]	ACQUISITIONS In March 2019, we completed the acquisition of all the issued and outstanding stock of a small private company for approximately $20.0 million . Cash payments, net of closing cash, consisted of $4.0 million paid in November 2018 and the remaining $16.0 million paid in March 2019. The acquisition was included in our Life Science segment's results of operations from the acquisition date and was accounted for as a business combination. The amount of acquisition-related costs was minimal as Bio-Rad primarily represented itself during the acquisition process. The goodwill related to this acquisition is not deductible for income tax purposes. Pro forma financial statements are not provided as the acquisition is immaterial to Bio-Rad taken as a whole for the periods presented. The preliminary allocation of the payments were $12.0 million to definite-lived intangibles, $10.7 million to goodwill, and a deferred tax liability of $2.7 million related to the purchased intangibles. The purchase price allocation is preliminary as additional time is required to complete the valuation of the intangibles.

Fair Value Disclosures [Abstract]
Fair Value Measurements	FAIR VALUE MEASUREMENTS We determine the fair value of an asset or liability based on the assumptions that market participants would use in pricing the asset or liability in an orderly transaction between market participants at the measurement date. The identification of market participant assumptions provides a basis for determining what inputs are to be used for pricing each asset or liability. A fair value hierarchy has been established which gives precedence to fair value measurements calculated using observable inputs over those using unobservable inputs. This hierarchy prioritizes the inputs into three broad levels as follows: • Level 1: Quoted prices in active markets for identical instruments • Level 2: Other significant observable inputs (including quoted prices in active markets for similar instruments) • Level 3: Significant unobservable inputs (including assumptions in determining the fair value of certain investments) Financial assets and liabilities carried at fair value and measured on a recurring basis as of March 31, 2019 are classified in the hierarchy as follows (in millions): Level 1 Level 2 Level 3 Total Financial Assets Carried at Fair Value: Cash equivalents: Commercial paper $ — $ 96.1 $ — $ 96.1 Asset backed — 0.4 — 0.4 Time deposits 10.0 10.0 — 20.0 Money market funds 39.7 — — 39.7 Total cash equivalents (a) 49.7 106.5 — 156.2 Restricted investment 5.6 — — 5.6 Equity securities (b) 3,692.7 — — 3,692.7 Available-for-sale investments: Corporate debt securities — 194.2 — 194.2 U.S. government sponsored agencies — 79.9 — 79.9 Foreign government obligations — 3.0 — 3.0 Other Foreign Obligations — 2.8 — 2.8 Municipal obligations — 10.9 — 10.9 Asset-backed securities — 66.8 — 66.8 Total available-for-sale investments (c) — 357.6 — 357.6 Forward foreign exchange contracts (d) — 0.6 — 0.6 Total financial assets carried at fair value $ 3,748.0 $ 464.7 $ — $ 4,212.7 Financial Liabilities Carried at Fair Value: Forward foreign exchange contracts (e) $ — $ 0.7 $ — $ 0.7 Contingent consideration (f) — — 6.5 6.5 Total financial liabilities carried at fair value $ — $ 0.7 $ 6.5 $ 7.2 Financial assets and liabilities carried at fair value and measured on a recurring basis as of December 31, 2018 are classified in the hierarchy as follows (in millions): Level 1 Level 2 Level 3 Total Financial Assets Carried at Fair Value: Cash equivalents: Commercial paper $ — $ 77.8 $ — $ 77.8 Time deposits 22.7 10.0 — 32.7 Asset-backed securities — 0.3 — 0.3 Money market funds 36.9 — — 36.9 Total cash equivalents (a) 59.6 88.1 — 147.7 Restricted investment 5.6 — — 5.6 Equity securities (b) 2,672.9 — — 2,672.9 Available-for-sale investments: Corporate debt securities — 215.0 — 215.0 U.S. government sponsored agencies — 80.3 — 80.3 Foreign government obligations — 3.6 — 3.6 Municipal obligations — 11.0 — 11.0 Asset-backed securities — 63.3 — 63.3 Total available-for-sale investments (c) — 373.2 — 373.2 Forward foreign exchange contracts (d) — 0.6 — 0.6 Total financial assets carried at fair value $ 2,738.1 $ 461.9 $ — $ 3,200.0 Financial Liabilities Carried at Fair Value: Forward foreign exchange contracts (e) $ — $ 0.7 $ — $ 0.7 Contingent consideration (f) — — 8.4 8.4 Total financial liabilities carried at fair value $ — $ 0.7 $ 8.4 $ 9.1 (a) Cash equivalents are included in Cash and cash equivalents in the Condensed Consolidated Balance Sheets.

At the acquisition date, the amount of contingent consideration was determined based on a probability-weighted income approach related to the achievement of sales milestones, ranging from 39% to 20% for the calendar years 2017 through 2020 . The sales milestones could potentially range from $0 to an unlimited amount. In the first quarter of 2019 , we paid $1.4 million per the purchase agreement. Since 2016 we have decreased the cumulative valuation of the sales milestones by net $12.7 million . The contingent consideration was accrued at its estimated fair value of $6.5 million as of March 31, 2019 . The following table provides a reconciliation of the Level 3 analytical flow cytometer platform contingent consideration liabilities measured at estimated fair value (in millions): December 31, 2018 $ 8.4 Payment of sales milestone (1.4 ) Decrease in estimated fair value of contingent consideration included in Selling, general and administrative expense (0.5 ) March 31, 2019 $ 6.5 The following table provides quantitative information about Level 3 inputs for fair value measurement of our analytical flow cytometer platform contingent consideration liability as of March 31, 2019 . Significant increases or decreases in these inputs in isolation could result in a significantly lower or higher fair value measurement. Valuation Technique Unobservable Input Analytical flow cytometer platform Probability-weighted income approach Sales milestones: Discount rate 12.0 % Cost of debt 4.7 % To estimate the fair value of Level 2 debt securities as of March 31, 2019 , our primary pricing provider uses Reuters as the primary pricing source. Our pricing process allows us to select a hierarchy of pricing sources for securities held. If Reuters does not price a Level 2 security that we hold, then the pricing provider will utilize our custodian supplied pricing as the secondary pricing source. For all commercial paper as of March 31, 2019 , our primary pricing provider uses its leading pricing source in the hierarchy to determine pricing. Our pricing provider performs daily reasonableness testing of the Reuters prices. Price changes of 5% or greater are investigated and resolved. In addition, we perform a quarterly testing of the Reuters prices to custodian reported prices. Price differences outside a tolerable variance of approximately 1% are investigated and resolved.

Because Bio-Rad has the ability and intent to hold these investments with unrealized losses until a recovery of fair value, or for a reasonable period of time sufficient for a forecasted recovery of fair value, which may be maturity, we do not consider these investments to be other-than-temporarily impaired at March 31, 2019 or at December 31, 2018 . As part of distributing our products, we regularly enter into intercompany transactions. We enter into forward foreign exchange contracts to manage foreign exchange risk of future movements in foreign exchange rates that affect foreign currency denominated intercompany receivables and payables. We do not use derivative financial instruments for speculative or trading purposes. We do not seek hedge accounting treatment for these contracts. As a result, these contracts, generally with maturity dates of 90 days or less and denominated primarily in currencies of industrial countries, are recorded at their fair value at each balance sheet date. The notional principal amounts provide one measure of the transaction volume outstanding as of March 31, 2019 and do not represent the amount of Bio-Rad's exposure to loss. The estimated fair value of these contracts was derived using the spot rates from Reuters on the last business day of the quarter and the points provided by counterparties. The resulting gains or losses offset exchange gains or losses on the related receivables and payables, both of which are included in Foreign currency exchange losses, net in the Condensed Consolidated Statements of Income. The following is a summary of our forward foreign exchange contracts (in millions): March 31, 2019 Contracts maturing in April through June 2019 to sell foreign currency: Notional value $ 41.9 Unrealized loss $ 0.2 Contracts maturing in April through June 2019 to purchase foreign currency: Notional value $ 249.9 Unrealized loss $ 0.1 The estimated fair value of our long-term debt, excluding leases and current maturities, that is not recognized at fair value in the Condensed Consolidated Balance Sheets has an estimated fair value based on quoted market prices for the same or similar issues. The estimated fair value of our long-term debt discussed above and the level of the fair value hierarchy within which the fair value measurement is categorized are as follows (in millions): March 31, 2019 December 31, 2018 Carrying Amount Estimated Fair Value Fair Value Hierarchy Level Carrying Amount Estimated Fair Value Fair Value Hierarchy Level Total long-term debt, excluding leases and current maturities $ 423.9 $ 436.9 2 $ 423.7 $ 435.8 2 Included in Other Investments in the Condensed Consolidated Balance Sheet are investments without readily determinable fair value measured at cost with adjustments for observable price changes in price or impairments.

The sale yielded net cash proceeds of $422.6 million at an effective rate of 4.946% . The 4.875% Notes pay a fixed rate of interest of 4.875% per year. We have the option to redeem any or all of the 4.875% Notes at any time at a redemption price of 100% of the principal amount (plus a specified make-whole premium as defined in the indenture governing the 4.875% Notes) and accrued and unpaid interest thereon to the redemption date. Our obligations under the 4.875% Notes are not secured and rank equal in right of payment with all of our existing and future unsubordinated indebtedness. Certain covenants apply at each year end to the 4.875% Notes including limitations on the following: liens, sale and leaseback transactions, mergers, consolidations or sales of assets and other covenants. We were in compliance with these covenants as of March 31, 2019 . There are no restrictive covenants relating to total indebtedness, interest coverage, stock repurchases, recapitalizations, dividends and distributions to shareholders or current ratios. Credit Agreement In June 2014, Bio-Rad entered into a $200.0 million unsecured Credit Agreement. Borrowings under the 2014 Credit Agreement are on a revolving basis and can be used to make permitted acquisitions, for working capital and for other general corporate purposes. We had no outstanding borrowings under the 2014 Credit Agreement as of March 31, 2019 or December 31, 2018 , however $0.2 million was utilized for domestic standby letters of credit that reduced our borrowing availability as of March 31, 2019 . If we had borrowed against our 2014 Credit Agreement, the borrowing rate would have been 3.725% at March 31, 2019 . The 2014 Credit Agreement was scheduled to mature in June 2019 but was renewed, and we entered into a new agreement in April 2019 for a maximum of $200.0 million on a revolving basis that will mature in April 2024. The 2019 Credit Agreement is substantially similar to the 2014 Credit Agreement. The borrowing rate for the 2019 Credit Agreement will be disclosed on a quarterly basis starting in the second quarter of 2019. The 2014 Credit Agreement requires Bio-Rad to comply with certain financial ratios and covenants, among other things. These ratios and covenants include a leverage ratio test and an interest coverage test, as well as restrictions on our ability to declare or pay dividends, incur debt, guarantee debt, enter into transactions with affiliates, merge or consolidate, sell assets, make investments and create liens. We were in compliance with all of these ratios and covenants as of March 31, 2019

Earnings Per Share [Abstract]
Earnings Per Share	. EARNINGS PER SHARE Basic earnings per share is computed by dividing net income attributable to Bio-Rad by the weighted average number of common shares outstanding for that period. Diluted earnings per share takes into account the effect of dilutive instruments, such as stock options and restricted stock, and uses the average share price for the period in determining the number of potential common shares that are to be added to the weighted average number of shares outstanding. Potential common shares are excluded from the diluted earnings per share calculation if the effect of including such securities would be anti-dilutive. The weighted average number of common shares outstanding used to calculate basic and diluted earnings per share, and the anti-dilutive shares that are excluded from the diluted earnings per share calculation are as follows (in thousands): Three Months Ended March 31, 2019 2018 Basic weighted average shares outstanding 29,801 29,787 Effect of potentially dilutive stock options and restricted stock awards 303 384 Diluted weighted average common shares 30,104 30,171 Anti-dilutive shares 226 41

Income Tax Disclosure [Abstract]
Income Taxes	. INCOME TAXES Our effective income tax rate was 23% and 24% for the three months ended March 31, 2019 and 2018 , respectively. The realization of deferred tax assets is dependent upon the generation of sufficient taxable income of the appropriate character in future periods. We regularly assess our ability to realize our deferred tax assets and establish a valuation allowance if it is more likely than not that some portion, or all, of our deferred tax assets will not be realized. In assessing the realizability of our deferred tax assets, we weigh all available positive and negative evidence. Due to the weight of objectively verifiable negative evidence, we believe that it is more likely than not that our California and certain foreign deferred tax assets will not be realized as of March 31, 2019 , and have maintained a valuation allowance on such deferred tax assets. Our income tax returns are routinely audited by U.S. federal, state and foreign tax authorities. We are currently under examination by many of these tax authorities. There are differing interpretations of tax laws and regulations, and as a result, significant disputes may arise with these tax authorities involving issues of the timing and amount of deductions and allocations of income among various tax jurisdictions. We evaluate our exposures associated with our tax filing positions on a quarterly basis. We record liabilities for unrecognized tax benefits related to uncertain tax positions. We do not believe any currently pending uncertain tax positions will have a material adverse effect on our condensed consolidated financial statements, although an adverse resolution of one or more of these uncertain tax positions in any period may have a material impact on the results of operations for that period. As of March 31, 2019 , based on the expected outcome of certain examinations or as a result of the expiration of statute of limitations for certain jurisdictions, we believe that within the next 12 months it is reasonably possible that our previously unrecognized tax benefits could decrease by up to $3.1 million

Net corporate operating, interest and other expense for segment results consists of receipts and expenditures that are not the primary responsibility of segment operating management and therefore are not allocated to the segments for performance assessment by our chief operating decision maker. Interest expense is charged to segments based on the carrying amount of inventory and receivables employed by that segment. For the three months ended March 31, 2019 compared to the same period in 2018 , our Life Science segment had increased sales and gross profit, while our Clinical Diagnostics segment had decreased sales and gross profit. Segment assets at March 31, 2019 increased from December 31, 2018 balances due to inclusion of operating lease right-of-use assets in segment assets (see Note 14, "Leases").

Legal Proceedings.	12. LEGAL PROCEEDINGS On May 27, 2015, our former general counsel, Sanford S. Wadler, filed a lawsuit in the U.S. District Court, Northern District of California, against us and four of our then current directors and one former director. The plaintiff’s suit alleged whistleblower retaliation in violation of the Sarbanes-Oxley Act and the Dodd-Frank Act for raising FCPA-related concerns. Mr. Wadler also alleged wrongful termination in violation of public policy, non-payment of wages and waiting time penalties in violation of the California Labor Code. The plaintiff sought back pay, compensatory damages for lost wages, earnings, retirement benefits and other employee benefits, compensation for mental pain and anguish and emotional distress, waiting time penalties, punitive damages, litigation costs (including attorneys’ fees) and reinstatement of employment. On July 28, 2015 we filed a motion to dismiss the plaintiff's complaint and specifically requested dismissal of the claims alleged against us under the Dodd-Frank Act and California Labor Code 1102.5 and the claims against the directors under the Sarbanes-Oxley Act and the Dodd-Frank Act. On October 23, 2015, the District Court granted our motion with respect to the alleged violations of the Sarbanes-Oxley Act against all the director defendants except Norman Schwartz with prejudice. The Court denied our motion to dismiss the claims under the Dodd-Frank Act as against both us and the director defendants. The trial commenced on January 17, 2017 and concluded on February 6, 2017. Mr. Wadler was awarded $10.92 million , plus prejudgment interest of $141,608 , post-judgment interest, and Mr. Wadler’s litigation costs, expert witness fees, and reasonable attorneys’ fees as approved by the Court. We have provided for the judgment, interest and Mr. Wadler's litigation costs. On June 6, 2017, we filed a notice of appeal with the United States Court of Appeals for the Ninth Circuit. Oral arguments occurred on November 14, 2018. On February 26, 2019, the United States Court of Appeals for the Ninth Circuit issued its decision, reversing in part, vacating in part, and affirming in part. Specifically, the court: (1) reversed the Dodd-Frank claim, which amounts to about $2.96 million plus interest, and directed the district court to enter judgment in Bio-Rad’s favor on that claim; (2) vacated the SOX claim due to instructional error and remanded for further proceedings, including whether a new trial is needed; and (3) affirmed the California public policy claim and the $7.96 million in damages attributable to it. On March 12, 2019 we filed a petition for panel rehearing or rehearing en banc with the United States Court of Appeals for the Ninth Circuit, and this petition was denied on April 8, 2019.

Restructuring Costs [Abstract]
Restructuring and Related Activities Disclosure [Text Block]	13. RESTRUCTURING COSTS Restructuring Costs for European Reorganization In May, 2016, we announced that we would take certain actions in our Europe geographic region designed to better align expenses to our revenue and gross margin profile and position us for improved operating performance. These actions, aligned with the creation and evolution of our organization structure and coordinated with the implementation of our global single instance enterprise resource planning ("ERP") platform, are expected to be incurred through 2019. We recorded approximately $(0.1) million of adjustments in restructuring charges related to severance and other employee benefits for the three months ended March 31, 2019 . The amounts recorded were reflected in Cost of goods sold of $(0.1) million in the Condensed Consolidated Statements of Income for the three months ended March 31, 2019 . From May 2016 to March 31, 2019 , total expenses were $12.7 million . The liability of $1.0 million as of March 31, 2019 was recorded in Accrued payroll and employee benefits in the Condensed Consolidated Balance Sheets. Restructuring Costs for Termination of a Diagnostics Research and Development Project and Facility Closures In December 2017, we announced the termination of a diagnostics research and development project in Europe. We recorded less than $(0.1) million of adjustments in restructuring charges related to severance and employee benefits for the three months ended March 31, 2019 . From December 2017 to March 31, 2019 , total expenses were $21.4 million . In June 2018, we announced the closure of a small manufacturing operation in Munich, Germany. We recorded $(0.1) million of adjustments in restructuring charges related to severance and employee benefits for the three months ended March 31, 2019 . From June 2018 to March 31, 2019 , total expenses were $1.6 million . In December 2018, we announced the closure of a small manufacturing facility outside Paris, France. We recorded $(0.1) million of adjustments in restructuring charges related to severance and employee benefits for the three months ended March 31, 2019 . From December 2018 to March 31, 2019 , total expenses were $4.0 million . Restructuring charges for the termination of a diagnostics research and development project and the facility closures are all included in our Clinical Diagnostics segment's results of operations. The amounts recorded were reflected in Cost of goods sold of $(0.2) million in the Condensed Consolidated Statements of Income for the three months ended March 31, 2019 . The liability of $7.5 million as of March 31, 2019 consisted of $3.6 million recorded in Accrued payroll and employee benefits, and $3.9 million recorded in Other long-term liabilities in the Condensed Consolidated Balance Sheets. The following table summarizes the activity for the termination of the diagnostics research and development project and the facility closures restructuring reserves for severance and exit costs (in millions): Balances as of December 31, 2018: $ 11.5 Adjustment to expense (0.2 ) Cash payments (3.6 ) Foreign currency translation gains (0.2 ) Balances as of March 31, 2019: $ 7.5

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Lessee, Leases [Policy Text Block]	Leases We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, other current liabilities, and operating lease liabilities in our condensed consolidated balance sheet as of March 31, 2019. Finance leases are included in property, plant and equipment, other current liabilities, and other long-term liabilities in our condensed consolidated balance sheet as of March 31, 2019. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Where we act as lessee, we elected not to separate lease and non-lease components and are more fully described in Note 14, Leases.
New Accounting Pronouncements, Policy [Policy Text Block]	Recent Accounting Pronouncements and Securities and Exchange Commission ("SEC") Rule Adopted In August 2018, the FASB issued ASU 2018-15, "Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract." ASU 2018-15 amends the definition of a hosting arrangement and requires a customer in a hosting arrangement that is a service contract to capitalize certain implementation costs as if the arrangement was an internal-use software project. The internal-use software guidance states that only qualifying costs incurred during the application development stage can be capitalized. We prospectively adopted ASU 2018-15 effective January 1, 2019. During the first quarter of 2019, we capitalized $0.7 million of implementation costs for cloud computing arrangements, net of accumulated amortization, primarily for business analytics software, and is recorded in Other current assets and Other assets in the Condensed Consolidated Balance Sheet. In August 2018, the SEC issued Final Rule Release No. 33-10532, "Disclosure Update and Simplification" that extends to interim periods the annual disclosure requirement of presenting the changes in stockholder' equity, which was effective in the first quarter of 2019. In February 2016, the FASB issued ASU 2016-02, "Leases," and related accounting standard updates, which requires, among other items, lease accounting to recognize most leases as assets and liabilities on the balance sheet. Qualitative and quantitative disclosures are enhanced to better understand the amount, timing and uncertainty of cash flows arising from leases. We adopted ASU 2016-02 on a modified retrospective basis effective January 1, 2019 with practical expedients, and did not restate comparative prior periods. Where we act as a lessee, the adoption of the standard resulted in material additions to the balance sheet for right-of-use assets and the associated liabilities, see Note 14, Leases. The practical expedients include, among other items, for leases that existed prior January 1, 2019, to not reassess whether any contracts are or contain embedded leases, reassessing the classification of existing leases, and reassessing whether previously capitalized initial direct costs qualify for capitalization. Where we act as a lessee, we also elected not to separate lease and non-lease components. Where we act as a lessor in reagent rental arrangements, there was an insignificant impact to our condensed consolidated financial statements, which is more fully described above under the caption "Reagent Rental Agreements." Recent Accounting Pronouncements to be Adopted In November 2018, the FASB issued ASU 2018-18, "Clarifying the Interaction between Topic 808 and Topic 606." Topic 808 is Collaborative Arrangements, and Topic 606 is Revenue from Contracts with Customers. ASU 2018-18 clarifies that certain transactions between collaborative partners should be accounted for as revenue under ASC 606 when the collaborative partner is a customer. We currently do not have any customers that are collaborative partners or anticipate any in the near future. ASU 2018-18 will be effective January 1, 2020. In August 2018, the FASB issued ASU 2018-14, "Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans." ASU 2018-14 eliminates and adds certain disclosures for defined benefit plans. ASU 2018-14 is effective for fiscal years ending after December 15, 2020 using a retrospective approach. We are currently evaluating the disclosures but do not expect ASU 2018-14 to have a material impact to our disclosures for defined benefit plans. In August 2018, the FASB issued ASU 2018-13, "Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement." ASU 2018-13 eliminates, adds and modifies certain disclosures for fair value measurements. ASU 2018-13 is effective for fiscal years beginning after December 15, 2019 and for interim periods within those fiscal years. We do not expect ASU 2018-13 to have a material impact to our fair value disclosures.
Revenue from Contract with Customer [Policy Text Block]	Revenue Recognition On January 1, 2018, we adopted Accounting Standards Codification ("ASC") 606, "Revenue from Contracts with Customers," using the modified retrospective method applied to those contracts that were not completed as of January 1, 2018. We recorded a net reduction to opening retained earnings of $0.1 million as of January 1, 2018 due to the cumulative impact of adopting ASC 606 with the impact primarily related to a customer loyalty program in the United States for which the resulting non-cash consideration is treated as variable consideration under the new revenue recognition accounting standard. We recognize revenue from operations through the sale of products, services, and rental of instruments. Revenue from contracts with customers is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration we expect to receive in exchange for those products or services. We enter into contracts that can include various combinations of products and services, which are generally accounted for as distinct performance obligations. Revenue is recognized net of any taxes collected from customers (sales tax, value added tax, etc.), which are subsequently remitted to government authorities. Our contracts from customers often include promises to transfer multiple products and services to a customer. Determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment, and may or may not impact the timing of revenue recognition. Revenue associated with equipment that requires factory installation is not recorded until installation is complete and customer acceptance, if required, has occurred. Certain equipment requires installation due to the fact that the instruments are being operated in a clinical/laboratory environment, and the installation services could result in modification of the equipment in order to ensure that the instruments are working according to specifications of the customer which are subject to validation tests upon completion of the installation. In these arrangements, which require factory installation, the delivery of the equipment and the installation are separate performance obligations. We will recognize the transaction price allocated to the equipment only upon customer acceptance, as the transfer of control has occurred in relation to the equipment at that point in time as the customer has the ability to direct the use of and obtain substantially all of the remaining benefits from the asset. The transaction price allocated to the installation services is also recognized upon completion of the services because without the completion of the installation services and related customer acceptance the customer cannot receive any of the benefits of the service. At the time revenue is recognized, a provision is recognized for estimated product returns as this right is considered variable consideration. Accordingly, when product revenues are recognized, the transaction price is reduced to the estimated amount that we expect to receive in exchange for transferring control for those products. Service revenues on extended warranty contracts are recognized ratably over the life of the service agreement as a stand-ready performance obligation. For arrangements that include a combination of products and services, transaction prices are allocated to performance obligations based on stand-alone selling prices. The method used to determine the stand-alone selling prices for service revenues is based on the observable prices when the services have been sold separately. In those instances where the timing of revenue recognition differs from the timing of invoicing, we have determined that our contracts generally do not include a significant financing component. The primary purpose of our invoicing terms is to provide customers with simple and predictable methods of purchasing our products and services, not to either provide or receive financing to or from our customers. We record contract liabilities when cash payments are received or due in advance of our performance. We do not disclose the value of unsatisfied performance obligations for contracts with an original expected length of one year or less and for contracts in which we recognize revenue at the amount to which we have the right to invoice for services performed. Our payment terms vary by the type and location of our customer, and the products and services offered. The term between invoicing and when payment is due is not significant. Reagent Rental Agreements Reagent rental agreements are a diagnostic industry sales method that provides use of an instrument and consumables (reagents) to a customer on a per test basis. These agreements may also include maintenance of the underlying instruments retained at customer locations as well as initial training. We initially determine if a reagent rental arrangement contains a lease at lease commencement. Where we have determined that such an arrangement contains a lease, we next must ascertain its lease classification for purposes of applying appropriate accounting treatment as an operating, sales-type or direct financing lease. In addition, for purposes of determining the lease term used in performing the lease classification test, we include the noncancellable period of the lease together with those periods covered by the option to extend the lease if the customer is reasonably certain to exercise that option, the periods covered by an option to terminate the lease if the customer is reasonably certain not to exercise that option, and the periods covered by the option to extend (or not to terminate) the lease in which exercise of the option is controlled by the company. While most of our reagent rental arrangements contain either the option for a lessee to extend and/or cancel, the period in which the contract is enforceable is a very short period and therefore the lease term has been limited to the non-cancellable period. Furthermore, it has historically been very rare for these arrangements to contain an option for the lessee to purchase the underlying asset. As discussed further below under the captions “Leases” and “Recent Accounting Pronouncements Adopted,” as well as in Note 14, Leases, we adopted ASC 842, “Leases,” on a modified retrospective basis effective January 1, 2019 with practical expedients, and did not restate comparative prior periods. We concluded that the use of the instrument (referred to as “lease elements”) is not within the guidance of ASC 606 but rather ASC 842. Accordingly, we first allocate the transaction price between the lease elements and the non-lease elements based on relative standalone selling prices. The determination of the transaction price requires judgment and consideration of any fixed/minimum payments as well as estimates of variable consideration. After allocation, the amount of variable payments allocated to lease components will be recognized as income under ASC 842, while the amount of variable payments allocated to non-lease components will be recognized as income in accordance with ASC 606. Upon our adoption of ASC 842 in 2019, the maintenance services, along with the reagents, are now allocated to the non-lease elements and will be recognized as income in accordance with ASC 606. This change is in alignment with the requirements of ASC 842, and has resulted in a decrease in the amount of rental income that is included in our total revenue. Generally, the terms of the arrangements result in the transfer of control on reagents upon either (i) when the consumables are delivered or (ii) when the consumables are consumed by the customer. Historically, our reagent rental arrangements have been predominantly comprised of variable lease payments, as very few of such arrangements contain any fixed/minimum lease payments. As a result, our lease income is heavily variable in nature with only relatively insignificant amounts of lease income comprised of fixed or stated minimum lease payments. Further, our reagent rental arrangements are predominantly classified as operating leases, with only very insignificant lease income associated with sales-type leases. Hence, our reported lease income is primarily variable in nature and is recognized over time as the reagents are consumed by the customer or delivered. Revenue allocated to the lease elements of these reagent rental arrangements represents approximately 3% and 5% of total revenue in the first quarter of 2019 compared to the first quarter of 2018, respectively, and is included as part of Net sales in our Condensed Consolidated Statements of Income. Contract costs: As a practical expedient, we expense as incurred costs to obtain contracts as the amortization period would have been one year or less. These costs, recorded within Selling, general and administrative expense, include our internal sales force compensation programs and certain partner sales incentive programs, as we have determined that annual compensation is commensurate with annual selling activities. Disaggregation of Revenue: The following table presents our revenues disaggregated by geographic region based primarily on the location of the use of the product or service (in millions, unaudited): Three Months Ended March 31, 2019 2018 Europe $ 185.9 $ 199.6 Pacific Rim 106.4 109.4 United States 226.1 209.9 Other (primarily Canada and Latin America) 35.6 32.6 Total Net sales $ 554.0 $ 551.5 The disaggregation of our revenue by industry segment sources is presented in our Segment Information footnote (see Note 11). Deferred revenues represent mostly unrecognized fees billed or collected for extended service arrangements. Deferred revenues are generally recognized ratably over the term of the service contract as our performance extends over the life of the arrangement. A majority of our deferred revenue balance is classified as current with an expected length of one year or less. The increase in our total deferred revenue balance from $37.3 million at December 31, 2018 to $41.1 million at March 31, 2019 is primarily driven by $15.2 million , net, of cash payments received or due in advance of satisfying our performance obligations, partially offset by $11.4 million of revenue recognized that were included in our deferred revenue balance as of December 31, 2018 . We warrant certain equipment against defects in design, materials and workmanship, generally for a period of one year. Upon revenue recognition of that equipment, we establish, as part of Cost of goods sold, a provision for the expected costs of such warranty based on historical experience, specific warranty terms and customer feedback. A review is performed on a quarterly basis to assess the adequacy of our warranty accrual. Components of the warranty accrual, included in Other current liabilities and Other long-term liabilities in the Condensed Consolidated Balance Sheets, were as follows (in millions): December 31, 2018 $ 10.1 Provision for warranty 1.4 Actual warranty costs (2.2 ) March 31, 2019 $ 9.3
