Basis of Presentation	Basis of Presentation The accompanying interim Consolidated Financial Statements are unaudited and have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) for interim financial information. All intercompany transactions and balances have been eliminated in the accompanying Consolidated Financial Statements.

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, 2022, 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, impairment analysis of goodwill, and restructuring reserves. 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.
Sales and Marketing Expenses	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 were immaterial for the three months ended March 31, 2023 and 2022.
Restructuring charges	Restructuring chargesRestructuring charges relate to a restructuring program to improve execution and drive efficiency across the organization. Restructuring charges consist of severance and other employee costs, costs for optimizing the Company’s geographic presence, and consulting and other costs.
Recently Accounting Pronouncements	Recent Accounting Pronouncements 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 adopted this standard as of January 1, 2023 and there was no impact on its Consolidated Financial Statements.
