Accounting Policies [Abstract]
Basis of Presentation	(1) BASIS OF PRESENTATION The accompanying condensed consolidated financial statements have been prepared by Myriad Genetics, Inc. (the “Company”) in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and pursuant to the applicable rules and regulations of the Securities and Exchange Commission (“SEC”). The condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. In the opinion of management, the accompanying financial statements contain all adjustments (consisting of normal and recurring accruals) necessary to present fairly all financial statements in accordance with GAAP. The condensed consolidated financial statements herein should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto for the fiscal year ended June 30, 2015, included in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2015. Operating results for the three and six months ended December 31, 2015 may not necessarily be indicative of results to be expected for any other interim period or for the full year. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

Acquisitions

Business Combinations [Abstract]
Acquisitions	(2) ACQUISITIONS German Clinic On February 27, 2015, the Company completed the acquisition of privately-held Privatklinik Dr. Robert Schindlbeck GmbH & Co. KG (the “Clinic”) approximately 15 miles from the Company’s European laboratories in Munich, Germany. The cash paid and preliminary total consideration transferred to acquire the Clinic was $20.1. Total consideration transferred was allocated to tangible assets acquired and liabilities assumed based on their preliminary fair values at the acquisition date as set forth below. The Company believes acquisition of the Clinic should facilitate the Company’s penetration into the German molecular diagnostic market. The Clinic will allow the Company to directly negotiate reimbursement with government and private insurance providers for its tests in the German market and collaborate with hospitals and physician groups. These factors contributed to consideration transferred in excess of the fair value of the Clinic’s net tangible and intangible assets acquired, resulting in the Company recording goodwill in connection with the transaction. Under German tax law the goodwill related to the purchase of the clinic is deductible and will be amortized for tax purposes over 15 years. Management estimated the fair value of tangible and intangible assets and liabilities in accordance with the applicable accounting guidance for business combinations and utilized the services of third-party valuation consultants. The preliminary allocation of the consideration transferred is subject to potential adjustments primarily due to tax-related matters, including tax basis of acquired assets and liabilities in the foreign jurisdiction, and third party valuations of acquired assets and liabilities, including actuarial analysis of pension assets and liabilities and fair value of equipment. During the measurement period, the Company may record adjustments to the provisional amounts recognized in the Company’s initial accounting for the acquisition. The Company expects the allocation of the consideration transferred to be final within the measurement period (up to one year from the acquisition date). Estimated Fair Current assets $ 3.1 Real property 20.7 Equipment 1.6 Goodwill 8.1 Current liabilities (4.4 ) Long-term liabilities (9.0 ) Total purchase price $ 20.1

Preferred and Common Stockholder's Equity	(9) PREFERRED AND COMMON STOCKHOLDER’S EQUITY The Company is authorized to issue up to 5.0 shares of preferred stock, par value $0.01 per share. There were no preferred shares outstanding at December 31, 2015. The Company is authorized to issue up to 150.0 shares of common stock, par value $0.01 per share. There were 71.6 shares issued and outstanding at December 31, 2015.

Diluted earnings per share is computed based on the weighted-average number of shares of common stock, including the dilutive effect of common stock equivalents, outstanding. The following is a reconciliation of the denominators of the basic and diluted earnings per share (“EPS”) computations: Three months ended Six months ended 2015 2014 2015 2014 Denominator: Weighted-average shares outstanding used to compute basic EPS 70.5 72.5 69.6 72.6 Effect of dilutive shares 3.3 2.9 3.5 3.2 Weighted-average shares outstanding and dilutive securities used to compute diluted EPS 73.8 75.4 73.1 75.8 Certain outstanding options and restricted stock units (“RSUs”) were excluded from the computation of diluted earnings per share because the effect would have been anti-dilutive. These potential dilutive common shares, which may be dilutive to future diluted earnings per share, are as follows: Three months ended Six months ended 2015 2014 2015 2014 Anti-dilutive options and RSU’s excluded from EPS computation — 0.9 — — Stock Repurchase Program In February 2015, the Company’s Board of Directors authorized a seventh share repurchase program of $200.0 of the Company’s outstanding common stock. The Company plans to repurchase its common stock from time to time or on an accelerated basis through open market transactions or privately negotiated transactions as determined by the Company’s management. The amount and timing of stock repurchases under the program will depend on business and market conditions, stock price, trading restrictions, acquisition activity and other factors. As of December 31, 2015, the Company has $91.6 remaining on its current share repurchase authorization. The Company uses the par value method of accounting for its stock repurchases. As a result of the stock repurchases, the Company reduced common stock and additional paid-in capital and recorded charges to accumulated deficit. The shares retired, aggregate common stock and additional paid-in capital reductions, and related charges to accumulated deficit for the repurchases for periods ended December 31, 2015 and 2014 were as follows: Three months ended Six months ended 2015 2014 2015 2014 Shares purchased and retired 0.6 1.7 1.7 3.0 Common stock and additional paid-in-capital reductions $ 5.4 $ 14.8 14.9 $ 25.0 Charges to retained earnings $ 20.0 $ 43.6 48.5 $ 79.0

Income Taxes

Income Taxes	6 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	(10) INCOME TAXES In order to determine the Company’s quarterly provision for income taxes, the Company used an estimated annual effective tax rate that is based on expected annual income and statutory tax rates in the various jurisdictions in which the Company operates. Certain significant or unusual items are separately recognized in the quarter during which they occur and can be a source of variability in the effective tax rate from quarter to quarter. Income tax expense for the three months ended December 31, 2015 was $14.7, or approximately 33% of pre-tax income, compared to $13.9, for the three months ended December 31, 2014, or approximately 37% of pre-tax income. Income tax expense for the six months ended December 31, 2015 was $31.6, or approximately 36% of pre-tax income, compared to $23.8, for the six months ended December 31, 2014, or approximately 37% of pre-tax income. Income tax expense for the three and six months ended December 31, 2015 is based on the Company’s estimated annual effective tax rate for the full fiscal year ending June 30, 2016, adjusted by discrete items recognized during the period. For the three and six months ended December 31, 2015, the Company’s recognized effective tax rate differs from the U.S. federal statutory rate of 35% primarily due to the effect of state income taxes, the reinstatement of the federal research tax credit, the sourcing of foreign losses and the benefits realized from the differences related to the earlier recognition of the tax effect of equity compensation expense from incentive stock options and the deduction realized when those options are disqualified upon exercise and sale. The Company files U.S., foreign and state income tax returns in jurisdictions with various statutes of limitations. The Company’s New Jersey State income tax returns for the years ended June 30, 2007 through 2013 are currently under examination by the State of New Jersey Department of Treasury, Division of Taxation. Annual and interim tax provisions include amounts considered necessary to pay assessments that may result from examination of prior year tax returns; however, the amount ultimately paid upon resolution of issues may differ materially from the amount accrued. The Company’s U.S. federal tax return and other state tax returns are not currently under examination. Pursuant to the guidelines of the recently issued Accounting Standards Update 2015-17 (“the Update”), all deferred tax assets and liabilities are to be classified as non-current. The effective date of the Update for public companies is for annual periods beginning after December 15, 2016 and later dates for all other entities. Early adoption is permitted. To comply with the guidance, the Company has elected to adopt this Update for the quarter ended December 31, 2015 and the annual period ending June 30, 2016. The guidance indicates that the Update may be applied either prospectively or retrospectively. The Company has chosen to apply the Update prospectively. Accordingly, no prior periods were adjusted. During the quarter ended December 31, 2015, approximately $13.5 of net current deferred tax assets were reclassified to non-current and netted against non-current deferred tax liabilities.

Share-Based Compensation

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Share-Based Compensation	(11) SHARE-BASED COMPENSATION The Company maintains a share-based compensation plan, the 2010 Employee, Director and Consultant Equity Incentive Plan, as amended (the “2010 Plan”), that has been approved by the Company’s shareholders. The 2010 Plan allows the Company, under the direction of the Compensation Committee of the Board of Directors, to make grants of stock options, restricted and unrestricted stock awards and other stock-based awards to employees, consultants and directors. On December 3, 2015, the shareholders approved an amendment to the 2010 Plan to add 1.6 to the number of shares of common stock available for grant. At December 30, 2015, 2.3 shares of common stock were available for issuance. If an option or RSU issued or awarded under the 2010 Plan is cancelled or expires without the issuance of shares of common stock, the unissued or reacquired shares, which were subject to the option or RSU, shall again be available for issuance pursuant to the 2010 Plan. In addition, as of December 31, 2015, the Company may grant up to 2.5 additional shares of common stock under the 2010 Plan if options previously granted under the Company’s terminated 2003 Employee, Director and Consultant Option Plan are cancelled or expire without the issuance of shares of common stock by the Company. The number of shares, terms, and vesting period of awards under the 2010 Plan are determined by the Compensation Committee of the Board of Directors for each equity award. Stock options granted under the plan prior to December 5, 2012 generally vest ratably over four years and expire ten years from the grant date. Stock options granted after December 5, 2012 generally vest ratably over four years and expire eight years from the grant date. The exercise price of options granted is equivalent to the fair market value of the stock on the grant date. In September 2014, the Company began issuing restricted stock units (“RSUs”) which generally vest ratably over four years on the anniversary date of the grant in lieu of stock options to employees and directors. Beginning in fiscal 2016, RSUs issued will generally vest ratably over four years from the last day of the month in which the RSU award is granted. The number of RSUs awarded to certain executive officers may be reduced if certain additional financial performance metrics are not met. Stock Options A summary of the stock option activity under the Company’s plans for the six months ended December 31, 2015 is as follows: Number Weighted Options outstanding at June 30, 2015 12.5 $ 23.49 Options granted — $ — Less: Options exercised (4.0 ) $ 21.38 Options canceled or expired — $ — Options outstanding at December 31, 2015 8.5 $ 24.50 Options exercisable at December 31, 2015 6.9 $ 24.00 As of December 31, 2015, there was $10.8 of total unrecognized share-based compensation expense related to stock options that will be recognized over a weighted-average period of 1.34 years. Restricted Stock Units A summary of the RSU activity under the Company’s plans for the six months ended December 31, 2015 is as follows: Number Weighted RSUs outstanding at June 30, 2015 1.0 $ 37.63 RSUs granted 0.8 $ 40.66 Less: RSUs vested (0.3 ) $ 39.74 RSUs canceled — $ — RSUs outstanding at December 31, 2015 1.5 $ 38.80 As of December 31, 2015, there was $39.0 of total unrecognized share-based compensation expense related to RSUs that will be recognized over a weighted-average period of 2.79 years. This unrecognized compensation expense is equal to the fair value of RSUs expected to vest. Employee Stock Purchase Plan The Company also has an Employee Stock Purchase Plan that was approved by shareholders in 2012 (the “2012 Purchase Plan”), under which 2.0 shares of common stock have been authorized.

Fair Value Disclosures [Abstract]
Fair Value Measurements	(12) FAIR VALUE MEASUREMENTS The fair value of the Company’s financial instruments reflects the amounts that the Company estimates it will receive in connection with the sale of an asset or pay in connection with the transfer of a liability in an orderly transaction between market participants at the measurement date (exit price). The fair value hierarchy prioritizes the use of inputs used in valuation techniques into the following three levels: Level 1 — quoted prices in active markets for identical assets and liabilities. Level 2 — observable inputs other than quoted prices in active markets for identical assets and liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Some of the Company’s marketable securities primarily utilize broker quotes in a non-active market for valuation of these securities. Level 3 — unobservable inputs. All of the Company’s financial instruments are valued using quoted prices in active markets or based on other observable inputs. For Level 2 securities, the Company uses a third party pricing service which provides documentation on an ongoing basis that includes, among other things, pricing information with respect to reference data, methodology, inputs summarized by asset class, pricing application and corroborative information. The Company reviews, tests and validates this information. The following table sets forth the fair value of the financial assets that the Company re-measures on a regular basis: Level 1 Level 2 Level 3 Total at December 31, 2015 Money market funds (a) $ 1.1 $ — $ — $ 1.1 Corporate bonds and notes — 59.6 — 59.6 Municipal bonds — 66.5 — 66.5 Federal agency issues — 44.3 — 44.3 Total $ 1.1 $ 170.4 $ — $ 171.5 (a) Money market funds are primarily comprised of exchange traded funds and accrued interest Level 1 Level 2 Level 3 Total at June 30, 2015 Money market funds (a) $ 2.4 $ — $ — $ 2.4 Corporate bonds and notes — 44.8 — 44.8 Municipal bonds — 70.3 — 70.3 Federal agency issues — 13.2 — 13.2 Total $ 2.4 $ 128.3 $ — $ 130.7 (a) Money market funds are primarily comprised of exchange traded funds and accrued interest
