UNSPSC 41131728: Prothrombin time test

In this classification a prothrombin time test is a device used as a general screening procedure for the detection of possible clotting factor deficiencies in the extrinsic coagulation pathway, which involves the reaction between coagulation factors III and VII, and to monitor patients receiving coumarin therapy (the administration of one of the coumarin anticoagulants in the treatment of venous thrombosis or pulmonary embolism) US FDA regulates Prothrombin time test under 21 CFR 864.7750 and under FDA product code GJS.

UNSPSC 41131728 Prothrombin time test is a Commodity code that does not align with actual state and local procurement activity in the recent opportunities block. The code nominally describes laboratory blood coagulation testing, yet the recent solicitations tagged under it reflect a much broader range of clinical and forensic laboratory services—offender drug testing programs, employment physicals and drug screening, urinalysis for family treatment court, clozapine assay kits for psychiatric monitoring, forensic drug standards for toxicology labs, breath alcohol testing equipment, and employment screening services including background investigations and criminal record searches. None of these opportunities involve prothrombin time testing specifically. The mismatch suggests either systematic miscoding in the state and local procurement systems or that the code has been repurposed to capture general laboratory and clinical testing services well beyond its nominal scope. State and local buyers posting under this code include county criminal justice and community supervision departments, county health agencies, city community college systems, state departments of public safety and mental health, and county forensic laboratories. Issuing bodies span Florida (Seminole County, Collier County, Clay County, Pinellas County), Oregon (state procurement and Benton County), Texas (Collin County), Illinois (City Colleges of Chicago), and Nevada (state department).

Recent opportunities show no concentration in any single jurisdiction or testing modality. Collin County Community Supervision and Corrections Department posted RFP 2026-327 on July 9, 2026, for offender specimen collection and drug testing services with proposals due July 23, 2026, at an estimated contract value of $600,000 over two years with renewal options; the scope covers immunoassay and confirmatory testing with SAMHSA or CAP lab certification required and approximately 25,031 annual tests. Benton County, Oregon solicited urinalysis testing services for its Family Treatment Court Program through RFP SC0200300017156 (posted June 6, 2026, due July 7, 2026), requiring CLIA-certified labs and twice-weekly testing with web-based reporting within 48–72 hours. Clay County and Collier County in Florida each posted invitations for pre-employment and fitness-for-duty physicals bundled with drug screening services in March and April 2026 respectively. City Colleges of Chicago issued RFP MWJ2603 (posted February 18, 2026, due March 30, 2026) for comprehensive employment screening including drug testing, background checks, and QuantiFERON-Gold testing, with 25% MBE and 7% WBE participation goals. Nevada's Department of Public Safety posted two separate bids in January 2026 for Intoxilyzer 9000 breath alcohol testing equipment. The code shows activity across the South, Midwest, and West, with no geographic concentration.
