UNSPSC 41131702: Antithrombin iii assay

In this classification an antithrombin III assay is a device that is used to determine the plasma level of antithrombin III (a substance which acts with the anticoagulant heparin to prevent coagulation). This determination is used to monitor the administration of heparin in the treatment of thrombosis US FDA regulates Antithrombin iii assay under 21 CFR 864.7060 and under FDA product code JPE.

UNSPSC 41131702 Antithrombin III assay, a Commodity code, does not align with the state and local procurement activity tagged under it. The recent opportunities show that jurisdictions are actually buying drug testing services, laboratory testing supplies, workplace drug screening, occupational medical services, forensic reference materials, and naloxone—none of which involve antithrombin III assay, a specialized coagulation blood test unrelated to the drug and occupational health testing dominating current activity. State and local governments soliciting under this code are primarily county criminal justice and health departments, county purchasing offices, state agencies, and municipal workforce health programs. The issuing bodies include Collin County (Texas) Supervision and Corrections, Gwinnett County (Georgia), the Texas Comptroller of Public Accounts, the City of Charlotte, Bernalillo County (New Mexico), and Benton County (Oregon), among others. The work being solicited spans offender drug testing operations with immunoassay and confirmatory testing, annual drug testing supplies for existing analyzer systems, laboratory diagnostic services for county health systems, occupational medical screenings and fitness-for-duty evaluations, forensic drug reference standards for law enforcement laboratories, and urinalysis testing for treatment court programs.

Activity is concentrated in Texas, Georgia, Oregon, Florida, Wisconsin, and New Mexico, with solicitations posted from mid-June through late September 2026. Representative recent opportunities include Collin County's RFP 2026-327 for offender specimen collection and drug testing services (approximately 25,031 tests annually, $600,000 estimated value, response date July 23, 2026); Benton County's urinalysis testing procurement for a family treatment court program (IFB, response date July 7, 2026); the Texas Comptroller's IFB 304T-27-175A1.1 for proprietary chemical laboratory equipment and supplies including DNA analysis and drug screening reagents (response date October 20, 2026); Gwinnett County's drug testing supplies solicitation for use with an existing drugs of abuse analyzer (RFQ, response date October 14, 2026); and Pinellas County's procurement of certified reference materials for forensic drug analysis standards (ITQ, response date April 23, 2026, with $49,034 allocated from federal Coverdell Act funds). The mismatch between the code name and the work being bought signals that either the code was misapplied at posting or this category sees minimal relevant state and local procurement activity.
