UNSPSC 41131727: Prothrombin-proconvertin test and thrombotest

In this classification a prothrombin-proconvertin test and thrombotest are devices used in the regulation of coumarin therapy (administration of a coumarin anticoagulant such as sodium warfarin in the treatment of venous thrombosis and pulmonary embolism) and as a diagnostic test in conjunction with, or in place of, the Quick prothrombin time test to detect coagulation disorders US FDA regulates Prothrombin-proconvertin test and thrombotest under 21 CFR 864.7735 and under FDA product code JPF.

UNSPSC 41131727 Prothrombin-proconvertin test and thrombotest, a Commodity code, nominally refers to laboratory coagulation assays, but recent state and local opportunities show little actual procurement activity under this specific code. Instead, the tagged opportunities reflect broader drug testing, employment screening, and forensic analysis services that fall outside the nominal scope of prothrombin or thrombotest procedures. The code does not appear to capture substantive state and local purchasing in its defined category; the opportunities present—including offender specimen collection and drug testing, employment physicals, and urinalysis screening—are epidemiologically and operationally distinct from coagulation factor testing and do not represent the clinical laboratory work the code purports to describe.

The geographic spread of opportunities spans Florida, Oregon, Nevada, Texas, Illinois, and a multi-state pattern typical of dispersed county and municipal procurement. Representative recent solicitations include Collin County Community Supervision and Corrections Department RFP 2026-327 for offender specimen collection and drug testing services (due July 23, 2026, estimated value $600,000), Benton County, Oregon urinalysis testing services for its Family Treatment Court Program (due July 7, 2026), and City Colleges of Chicago RFP MWJ2603 for employment screening services including pre-employment drug testing and fitness-for-duty evaluations (due March 30, 2026). Issuing bodies include county criminal justice departments, municipal colleges, and county human resources and public safety agencies. The code shows insufficient alignment with its stated taxonomy definition to support targeted business development activity.
