Accounting Policies [Abstract] |
Description of Business [Policy Text Block] | Description of Business In this quarterly report on Form 10-Q, Mesa Laboratories, Inc., a Colorado corporation, together with its subsidiaries, is collectively referred to as “we,” “us,” “our,” the “Company” or “Mesa.” We are a multinational manufacturer, developer, and seller of life science tools and critical quality control products and services, many of which are sold into niche markets that are driven by regulatory requirements. We have manufacturing operations in the United States and Europe, and our products are marketed by our sales personnel in North America, Europe, and Asia Pacific, and by independent distributors in these areas as well as throughout the rest of the world. We prefer markets in which we can establish a strong presence and achieve high gross profit margins. As of December 31, 2022, we managed our operations in four reportable segments, or divisions:
| ● | Clinical Genomics - develops, manufactures, and sells highly sensitive, low-cost, high-throughput genetic analysis tools used by clinical labs to perform genomic clinical testing in several therapeutic areas, such as screenings for hereditary diseases, pharmacogenetics and oncology related applications.
| ● | Sterilization and Disinfection Control - manufactures and sells biological, cleaning, and chemical indicators which are used to assess the effectiveness of sterilization and disinfection processes in the hospital, medical device, and pharmaceutical industries. The division also provides testing and laboratory services, mainly to the dental industry.
| ● | Biopharmaceutical Development - develops, manufactures, and sells automated systems for protein analysis (immunoassays) and peptide synthesis solutions. Immunoassays and peptide synthesis solutions accelerate the discovery, development, and manufacture of biotherapeutic drugs.
| ● | Calibration Solutions - develops, manufactures, and sells quality control and calibration products used to measure or calibrate temperature, pressure, pH, humidity, and other chemical or physical parameters for health and safety purposes, primarily in hospital, medical device manufacturing, pharmaceutical manufacturing, and various laboratory environments.
Non-reportable operating segments and unallocated corporate expenses are reported within Corporate and Other.
Basis of Accounting, Policy [Policy Text Block] | Basis of Presentation The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission and in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information. In the opinion of management, such unaudited information includes all adjustments, consisting of normal recurring adjustments necessary for the fair statement of our financial position and results of operations. The results of operations for the interim periods are not necessarily indicative of results that may be achieved for the entire year. The year-end Condensed Consolidated Balance Sheet data was derived from audited financial statements but does not include all disclosures required by accounting principles generally accepted in the United States of America. We made no material changes to the application of our significant accounting policies that were disclosed in our Form 10-K. This quarterly report should be read in conjunction with the consolidated financial statements included in our annual report on Form 10-K for the year ended March 31, 2022. Our fiscal year ends on March 31. References in this Quarterly Report to a particular “year” or “year-end” mean our fiscal year, references to the first quarter of fiscal year 2023 refer to the period from April 1, 2022 through June 30, 2022, references to the second quarter of fiscal year 2023 refer to the period from July 1, 2022 through September 30, 2022, and references to the third quarter of fiscal year 2023 refer to the period from October 1, 2022 through December 31, 2022. References to “fiscal year 2022” refer to the fiscal year ended March 31, 2022, and to “fiscal year 2023” refer to the fiscal year ending March 31, 2023.
Reclassification, Comparability Adjustment [Policy Text Block] | Prior Period Reclassification Certain amounts presented for prior periods in Note 3. "Revenue Recognition" have been reclassified. Certain revenues related to the Biopharmaceutical Development division have been reclassified out of revenues from consumables and into revenues from hardware and services. Certain revenues related to the Clinical Genomics division have been reclassified out of revenues from hardware and into revenues from consumables. These reclassifications have not resulted in any change to the Condensed Consolidated Financial Statements for and periods presented in this Form 10-Q.
Risk and Uncertainties, Policy [Policy Text Block] | Risks and Uncertainties The preparation of financial statements requires the use of estimates and assumptions that affect the reported amounts of assets and liabilities at the reporting date and revenues and expenses during the reporting periods. These estimates represent management's judgment about the outcome of future events. The business and economic uncertainty resulting from supply chain challenges, cost pressure, the overall effects of the current high inflation environment on customers' purchasing patterns, and the novel coronavirus pandemic ("COVID-19") has made such estimates more difficult to calculate. Accordingly, actual results could differ from those estimates.
New Accounting Pronouncements, Policy [Policy Text Block] | Recently Issued Accounting Pronouncements We have reviewed all recently issued accounting pronouncements and have concluded that they are either not applicable to us or are not expected to have a significant impact on our consolidated financial statements.
