Accounting Policies [Abstract]
Basis of Presentation and Consolidation	The accompanying interim Condensed Consolidated Financial Statements are unaudited. The interim unaudited Condensed Consolidated Financial Statements have been prepared on a basis consistent with the annual consolidated financial statements and, in the opinion of management, reflect all adjustments, which include normal, recurring adjustments, necessary to present fairly the financial position of the Company as of September 30, 2021, and the results of our operations and statements of stockholders' equity for the three and nine months ended September 30, 2021 and 2020, and cash flows for the nine months ended September 30, 2021 and 2020. The unaudited Condensed Consolidated Financial Statements included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") have been condensed or omitted pursuant to such rules and regulations. Our unaudited Condensed Consolidated Financial Statements include our accounts and the accounts of our wholly-owned subsidiaries since their respective dates of acquisitions. All intercompany accounts and transactions have been eliminated in consolidation. Where our ownership of a subsidiary is less than 100%, the non-controlling interest is reported on our Condensed Consolidated Balance Sheets. The non-controlling interest in our consolidated net (loss) income is reported as "Net loss attributable to redeemable non-controlling interest" on our Condensed Consolidated Statements of Loss. The results of operations for the nine months ended September 30, 2021 are not necessarily indicative of the results to be expected for the full year or any future period, particularly in light of the COVID-19 pandemic and its effects on the domestic and global economies as described below. These unaudited Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and Notes thereto contained in our Annual Report on Form 10-K for the year ended December 31, 2020 and other financial information filed with the SEC. Beginning in the first quarter of 2020, to limit the spread of COVID-19, governments took various actions including the issuance of stay-at-home policies and social distancing procedures and guidelines, causing some businesses to adjust, reduce or suspend business and operating activities. Veterinary care is widely recognized as an "essential" service for pet owners, and veterinarians continued to deliver essential medical care for sick and injured pets. The stay-at-home policies deployed early in 2020 to combat the spread of COVID-19 resulted in a decrease in companion animal clinical visits, including delay of elective procedures and wellness visits and as a result, lower demand for diagnostic testing services. Beginning in the second quarter of 2020, certain local, state and federal governments began to ease the stay-at-home policies and allowed more businesses and facilities to re-open, leading to a recovery in companion animal clinical visits and associated demand for our diagnostic products. During the fourth quarter of 2020 and into the first quarters of 2021, increased restrictions in countries in which we operate, mainly in the European Union, and certain parts of Canada and Australia, re-emerged. In some part due to the introduction and acceptance of COVID-19 vaccines, restrictions eased in many of the countries in which we operate during the second and third quarter of 2021; however, with the rise in COVID-19 variants, the extent to which the continuation, or another wave, of COVID-19, or an outbreak of other health epidemics could impact our business, results of operations and financial condition, including the potential for write-offs or impairments of assets and suspension of capital investments, will depend on future developments. We are unable to predict with certainty the effects of the COVID-19 pandemic on our customers, suppliers and vendors, as well as the actions of governments, and when and to what extent normal economic and operating conditions can resume; these effects may differ from those assumed in our projected estimates. Even after the COVID-19 pandemic has subsided, we may continue to experience adverse impacts to our business, mainly in our ability to place new capital equipment, primarily under long-term contracts, and manage supply chain shortages and increased costs, as a result of any economic impact that may occur in the future.
Use of Estimates	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, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates are required when establishing the allowance for credit losses and the net realizable value of inventory; determining future costs associated with warranties provided; determining the period over which our obligations are fulfilled under agreements to license product rights and/or technology rights; evaluating long-lived and intangible assets and investments for estimated useful lives and impairment; estimating the useful lives and standalone selling prices of instruments under leasing arrangements; determining the allocation of purchase price under purchase accounting; estimating the expense associated with the granting of stock; determining the need for, and the amount of a valuation allowance on deferred tax assets; determining the fair value of our embedded derivatives; and determining the value of the non-controlling interest in a business combination. Our actual results may differ from these estimates and there may be changes to those estimates in future periods.
Fair Value of Financial Instruments	The Company's financial assets based upon Level 3 inputs include embedded derivatives relating to its note receivables. The Company determined the redemption features of its convertible note receivable represents an embedded derivative. The estimated fair value of the embedded derivative asset is evaluated through Level 3 inputs using a probability-weighted scenario analysis. The Company determined the warrant associated with its promissory note receivable represents a derivative. The estimated fair value of the derivative asset is evaluated through Level 3 inputs, using an enterprise valuation model. For additional information regarding the Company's note receivables and derivatives, refer to Note 17, Notes Receivable. The estimated fair value of the Company's 3.75% Convertible Senior Notes due in 2026 (the "Notes"), is disclosed at each reporting period and is evaluated through Level 2 inputs with consideration of quoted market prices in less active markets. For additional information regarding the Company's accounting treatment for the issuance of the Notes, refer to Note 16, Convertible Notes. The Company's financial liabilities based upon Level 3 inputs include contingent consideration arrangements and notes payable relating to its acquisitions of Lacuna, BiEsseA and Biotech. The Company is obligated to pay contingent consideration payments of $2.0 million in connection with the Lacuna acquisition based on the achievement of certain performance metrics within a twelve month period ("Initial Earn Out Period"), reducing to $1.0 million if such metrics were met in a twelve month period subsequent to the Initial Earn Out Period. The Company is obligated to pay contingent consideration payments of $2.9 million in connection with the BiEsseA acquisition based on the achievement of certain revenue metrics within three annual periods after 2021. The Company is obligated to pay contingent notes of up to $17.5 million in connection with the Biotech acquisition based on the achievement of certain product development milestones or at a predetermined date in the future. Refer to Note 3, Acquisitions and Related Party Items for further discussion. The fair value of our contingent consideration and notes payable arrangements are determined based on a probability-weighted outcome analysis. The fair value of the contingent consideration and notes payable liabilities associated with future payments were based on several factors, the most significant of which are the financial and product development performance of the acquired businesses. The Company will update its assumptions each reporting period based on new developments and record such amounts at fair value based on the revised assumptions until the agreements expire. Changes in fair value are recorded in the Consolidated Statements of Loss within general and administrative expenses.
Adoption of New Accounting Pronouncements	Adoption of New Accounting Pronouncements Effective January 1, 2021, we adopted ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which is intended to simplify various aspects related to the accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in Topic 740, and also clarifies and amends existing guidance to improve consistent application. We evaluated the impact of the standard on our consolidated financial statements and the adoption of this ASU did not have a material impact on our consolidated financial statements and disclosures. Effective January 1, 2021, we adopted ASU 2020-01, Investments-Equity Securities (Topic 321), Investments-Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815). The amendments in this ASU clarify the interaction between the accounting for investments in equity securities, investments in equity method and certain derivatives instruments. The ASU is expected to reduce diversity in practice and increase comparability of the accounting for these interactions. We evaluated the impact of the standard on our consolidated financial statements and the adoption of this ASU did not have a material impact on our consolidated financial statements and disclosures. Effective January 1, 2021, we early adopted ASU 2020-06, Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40), which simplifies the accounting for certain convertible instruments. The update reduces the number of accounting models for convertible debt instruments and convertible preferred stock. Convertible debt will be accounted for as a single liability measured at its amortized cost and convertible preferred stock will be accounted for as a single equity instrument measured at its historical cost, as long as no other features require bifurcation and recognition as derivatives. The update also requires the if-converted method to be used for convertible instruments and the effect of potential share settlement be included in the diluted earnings per share calculation when an instrument may be settled in cash or shares. The Company's 3.75% Convertible Senior Notes due 2026 (the "Notes") are a convertible instrument with a cash-conversion feature that is accounted for within the scope of ASC 470-20 and impacted by the adoption of ASU 2020-06. The Company has elected to apply the modified retrospective method wherein the Company recognized a cumulative-effect adjustment to the opening balance of retained earnings (January 1, 2021). Further, the Company will not restate EPS in prior periods. The Company calculated the cumulative-effect adjustment as of January 1, 2021 by comparing (i) the historical amortization schedule for the Notes through December 31, 2020 and (ii) an updated amortization schedule wherein the conversion feature within the Notes would not be separated as an equity component and subsequently recognized as non-cash interest expense under ASC 835-30. As a result of ASU 2020-06, while cash interest expense is not impacted, non-cash interest accretion is limited to the amortization of debt issuance costs under ASC 835-30. Therefore, the Company prepared its transition journal entries by (i) reversing the conversion feature amount recorded in APIC and (ii) reversing the difference in non-cash interest expense via retained earnings. The adoption resulted in a decrease to accumulated deficit of $3.4 million, a decrease to additional paid-in capital of $29.8 million, and an increase to convertible note, non-current, net of $35.2 million. Additionally, due to the adoption, the Company reversed the remaining balance of the net deferred tax liability of $8.8 million, which was initially recorded in connection with the Notes. Effective January 1, 2021, we adopted ASU 2020-10, Codification Improvements, which updates various codification topics by clarifying or improving disclosure requirements to align with the SEC's regulations. We evaluated the impact of the standard on our consolidated financial statements and the adoption of this ASU did not have a material impact on our consolidated financial statements and disclosures. In July 2021, the Financial Accounting Standards Board (the "FASB") issued ASU 2021-05, Leases (Topic 842), Lessors- Certain Leases with Variable Lease Payments. This guidance amends the lease classification accounting for lessors for certain leases with variable lease payments that do not depend on a reference index or a rate and would have resulted in the recognition of a loss at lease commencement if classified as a sale-type or direct financing lease. Under the new guidance, these leases will be classified as an operating lease. The amendment is effective for fiscal years beginning after December 15, 2021, with early adoption permitted. We do not expect adoption of the new guidance to have a material impact on our financial statements.
