Accounting Changes and Error Corrections [Abstract]
Basis of Presentation	Basis of Presentation The accompanying interim Consolidated Financial Statements are unaudited and have been prepared in accordance with GAAP for interim financial information. All intercompany transactions and balances have been eliminated in the accompanying Consolidated Financial Statements. The accounting policies of the Company are the same as those set forth in Note 2. Summary of Significant Accounting Policies, to the audited Consolidated Financial Statements contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021, except for new accounting standards discussed under Recent Accounting Pronouncements.
Use of Estimates	Use of Estimates The Company prepares its Consolidated Financial Statements in conformity with GAAP. These principles require management to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, together with amounts disclosed in the related notes to the Consolidated Financial Statements. Actual results and outcomes may differ from management’s estimates, judgments and assumptions. Significant estimates, judgments and assumptions used in these Consolidated Financial Statements include, but are not limited, to those related to revenues, accounts receivable and related allowances, contingencies, useful lives and recovery of long-term assets and intangible assets, income taxes and valuation allowances, stock-based compensation, business combinations, and impairment analysis of goodwill. These estimates, judgments, and assumptions are reviewed periodically and the effects of material revisions in estimates are reflected on the Consolidated Financial Statements prospectively from the date of the change in estimate.
Assets Held for Sale	Assets Held for Sale Assets to be disposed of by sale are reclassified as held for sale if their carrying amounts are expected to be recovered through a sale transaction rather than through continuing use and when the Company commits to a plan to sell the assets. Assets classified as held for sale are measured at the lower of their carrying value or fair value less selling costs. Such assets are classified within current assets if there is reasonable certainty that the sale and collection of consideration will take place within one year. Upon reclassification as held for sale, long-lived assets are no longer depreciated or amortized and a measurement for impairment is performed to determine if there is an excess of carrying value over fair value less costs to sell. Any remeasurement is reported as an adjustment to the carrying value of the assets. Subsequent changes to estimated fair value less the selling costs will impact the measurement of assets held for sale if the fair value is determined to be less than the carrying value of the assets.
Goodwill	GoodwillThe Company evaluates goodwill on an annual basis in the fourth quarter or more frequently if management believes indicators of impairment exist. Such indicators could include, but are not limited to, (1) a significant adverse change in legal factors or in business climate, (2) unanticipated competition, or (3) an adverse action or assessment by a regulator. The Company first assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill. If management concludes that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, management performs a quantitative goodwill impairment test. The quantitative analysis is performed by comparing the fair value of the reporting unit to its carrying value. If the carrying value is greater than the estimate of fair value, an impairment loss will be recognized for the amount in which the carrying amount exceeds the reporting unit’s fair value. The Company estimates the fair values of its reporting units using a combination of the income, or discounted cash flows approach and the market approach, which utilizes comparable companies’ data.
Sales and Marketing Expense	Sales and Marketing Expenses Sales and marketing expenses are primarily attributable to employee-related costs including sales management, sales representatives, sales and marketing consultants, and marketing and customer service personnel in the Clinical Services segment. Advertising costs are expensed at the time they are incurred and are deemed immaterial for the three and six months ended June 30, 2022 and 2021.
Recently Accounting Pronouncements	Recent Accounting Pronouncements In November 2021, the FASB issued ASU No. 2021-10, Government Assistance (Topic 832), Disclosures by Business Entities about Government Assistance (“ASU 2021-10”). This update requires business entities to disclose information annually about certain government assistance they receive. Such annual disclosure requirements include the nature of the transactions and the related accounting policy used, the line items on the balance sheet and income statement that are affected and the amounts applicable to each financial statement line item and significant terms and conditions of the transactions. ASU 2021-10 is effective for annual periods beginning after December 15, 2021, with early adoption permitted. ASU 2021-10 should be applied either (1) prospectively to all transactions within the scope of the amendments that are reflected in financial statements at the date of initial application and new transactions that are entered into after the date of initial application or (2) retrospectively to those transactions. The Company will adopt this new accounting standard in its Annual Report on Form 10-K for the year ended December 31, 2022 and does not expect the adoption of this standard to have a material impact on its Consolidated Financial Statements. In October 2021, the FASB issued ASU No. 2021-08, Business Combinations (Topic 805), Accounting for Contract Assets and Contract Liabilities from Contracts with Customers (“ASU 2021-08”). This update amends guidance to require that an entity (acquirer) recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Revenue from Contracts with Customers (Topic 606). At the acquisition date, an acquirer should account for the related revenue contracts in accordance with Topic 606 as if it had originated the contracts. ASU 2021-08 is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Early adoption of the amendments is permitted including adoption in an interim period. If the Company early adopts in an interim period, the Company is required to apply the amendments (1) retrospectively to all business combinations for which the acquisition date occurs on or after the beginning of the fiscal year that includes the interim period of early application and (2) prospectively to all business combinations that occur on or after the date of initial application. The amendments in ASU 2021-08 should be applied prospectively to business combinations occurring on or after the effective date of the amendments. The Company is currently evaluating its adoption date of this standard and the impact of the standard on its Consolidated Financial Statements. In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU 2020-04”) which provides for temporary optional expedients and exceptions to the current guidance on certain contract modifications and hedging relationships to ease the burdens related to the expected market transition from the London Inter-bank Offered Rate (“LIBOR”) or other reference rates to alternative reference rates. In January 2021, the FASB issued ASU No. 2021-01, Reference Rate Reform (Topic 848) (“ASU 2021-01”) to clarify that certain optional expedients and exceptions apply to modifications of derivative contracts and certain hedging relationships affected by changes in the interest rates used for discounting cash flows, computing variation margin settlements, and for calculating price alignment interest. ASU 2020-04 was effective beginning on March 12, 2020 and may be applied prospectively to such transactions through December 31, 2022 and ASU 2021-01 was effective beginning on January 7, 2021 and may be applied retrospectively or prospectively to such transactions through December 31, 2022. The Company will evaluate transactions or contract modifications occurring as a result of reference rate reform and determine whether to apply the optional guidance on an ongoing basis. As of June 30, 2022, there was no impact to the Company’s Consolidated Financial Statements related to ASU 2020-04 or ASU 2021-01.
