Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	BASIS OF PRESENTATION Myriad Genetics, Inc. and its subsidiaries (collectively, the “Company” or “Myriad”) is a leading genetic testing and precision medicine company dedicated to advancing health and well-being for all. Myriad provides insights that help people take control of their health and enable healthcare providers to better detect, treat, and prevent disease. Myriad develops and commercializes genetic tests that help assess the risk of developing disease or disease progression or guide treatment decisions across medical specialties. The Company generates revenue by performing molecular diagnostic tests and, prior to the sale of Myriad RBM, Inc. on July 1, 2021, by providing pharmaceutical services to the pharmaceutical and biotechnology industries and medical research institutions utilizing its multiplexed immunoassay technology. The Company currently operates as a single reporting segment. The Company’s corporate headquarters are located in Salt Lake City, Utah. The accompanying Condensed Consolidated Financial Statements for the Company have been prepared 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”). 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 included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021 (the “Form 10-K”). The preparation of financial statements in conformity with 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. Operating results for the three months ended March 31, 2022 may not necessarily be indicative of results to be expected for any other interim period or for the full year. The Company has historically experienced seasonality in its testing business. In the quarters ended March 31, the Company has typically experienced a decrease in volumes due to the annual reset of patient deductibles. Additionally, the volume of testing is negatively impacted by the summer season, which is generally reflected in the quarter ended September 30th. The quarter ended December 31 is generally strong as the Company typically experiences an increase in volumes from patients who have met their annual insurance deductible. Due to the ongoing COVID-19 global pandemic, including variants of COVID-19 (“COVID-19”), seasonality may not follow the same pattern as in prior years. Volumes and results of operations were impacted negatively in calendar year 2021 and early 2022 by COVID-19. As such, the Company’s year over year results may not be comparable. Management continues to monitor the impact of COVID-19 on the Company’s financial condition, liquidity, operations, suppliers, industry, and workforce. Given the variants of COVID-19 that have surfaced around the world, the Company is not able to fully estimate the effects of COVID-19 on its results of operations, financial condition, or liquidity for future periods. Reclassifications Certain prior period amounts have been reclassified to conform with the current period's presentation. The reclassifications have no impact on the total assets, total liabilities, stockholders’ equity, cash flows from operations, or net loss for the period.
