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 does not align with the recent state and local procurement activity tagged under it. The source shows recent solicitations from Collin County, Gwinnett County, Texas Comptroller, Charlotte, Bernalillo County, Benton County, Oregon, Pinellas County, the University of Wisconsin-Madison, and Seminole County acquiring drug testing supplies, drug screening services, laboratory services, occupational medical services, drug standards for forensic analysis, naloxone and drug deactivation systems, and clozapine assay kits—none of which are platelet factor 4 radioimmunoassay tests. The code's nominal scope (platelet factor 4 radioimmunoassay, a specialized immunological assay) bears no operational relationship to the forensic toxicology, occupational health screening, and controlled-substance drug testing dominating the tagged opportunities.

Recent activity spans Texas (Collin County offender drug testing and lab services), Georgia (Gwinnett County drug testing supplies), North Carolina (Charlotte drug and alcohol testing), New Mexico (Bernalillo County occupational medical services), Oregon (Benton County urinalysis and statewide clozapine assay sole source), Florida (Seminole County naloxone procurement, Pinellas County drug standards), Wisconsin (University of Wisconsin-Madison blood draw kits), and a Texas statewide procurement for laboratory consumables and forensic reagents. The mismatch between code assignment and actual procurement scope suggests either a data-entry error in code tagging or a fundamental misclassification of the commodity. Practitioners should treat this code as showing little relevant recent activity for platelet factor 4 radioimmunoassay procurement at the state and local level.
