UNSPSC 41131725: Platelet factor 4 radioimmunoassay

In this classification a platelet factor 4 radioimmunoassay is a device used to measure the level of platelet factor 4, a protein released during platelet activation by radioimmunoassay. This device measures platelet activiation, which may indicate a coagulation disorder, such as myocardial infarction or coronary artery disease US FDA regulates Platelet factor 4 radioimmunoassay under 21 CFR 864.7695 and under FDA product code LCO.

UNSPSC 41131725 Platelet factor 4 radioimmunoassay is a Commodity code that shows minimal relevant recent state and local procurement activity. The recent opportunities tagged to this code do not align with the nominal scope of a radioimmunoassay test for a specific blood clotting factor. Instead, the opportunities center on drug testing services, employment screening, breath alcohol testing equipment, and forensic drug standards — all of which fall outside the platelet factor 4 assay domain. The only solicitation with potential technical relevance is the State of Oregon's May 2026 sole-source procurement for a MyCare Psychiatry Clozapine Assay Kit and Controls from Saladax Biomedical, which addresses psychiatric drug-level monitoring rather than hematologic testing. The issuing bodies in the recent record span state departments, county corrections and health agencies, municipal colleges, and forensic laboratories across Oregon, Florida, Nevada, and Texas; however, none are actively procuring platelet factor 4 radioimmunoassay services or materials.

This code does not reflect current state and local procurement demand for platelet factor 4 testing. The tagging mismatch suggests either upstream classification errors in how opportunities are indexed to UNSPSC codes, or genuine absence of state and local solicitation activity in this narrow assay category during the recent period captured. Firms evaluating this code should verify directly with state laboratory procurement offices, state health departments, and regional clinical reference laboratories whether platelet factor 4 radioimmunoassay testing or reagent supply contracts are in active planning or pre-solicitation development, as the code's recent posting record does not support near-term pursuit.
