UNSPSC 41131724: Leukocyte peroxidase test

In this classification a leukocyte peroxidase test is a device used to distinguish certain myeloid cells derived from the bone marrow, i.e., neutrophils, eosinophils, and monocytes, from lymphoid cells of the lymphatic system and erythroid cells of the red blood cell series on the basis of their peroxidase activity as evidenced by staining US FDA regulates Leukocyte peroxidase test under 21 CFR 864.7675 and under FDA product code GIA.

UNSPSC 41131724 Leukocyte peroxidase test, a Commodity code, does not align with the recent state and local contract opportunities posted under it. The nine opportunities in the recent-activity block span drug testing services, laboratory supplies for forensic and clinical applications, naloxone procurement, occupational health screening, and psychiatric assay kits—none of which concern leukocyte peroxidase testing specifically. The code appears to have been applied to solicitations covering broader drug-screening panels, immunoassay and chromatographic confirmations, forensic toxicology reference materials, and general clinical laboratory services where leukocyte peroxidase testing is not a named scope element.

State and local buyers posting under this code include county community supervision and corrections departments, county health care services, county forensic laboratories, city occupational health programs, county family treatment courts, and state health agencies. Collin County, Texas (Community Supervision and Corrections Department and Health Care Services) appears twice in the recent block, and Pinellas County, Florida; Gwinnett County, Georgia; Benton County, Oregon; and Bernalillo County, New Mexico each solicited once. The geographic spread spans Texas, Georgia, Florida, Oregon, North Carolina, New Mexico, and Wisconsin. Representative recent opportunities include Collin County's RFP 2026-327 for offender specimen collection and drug testing services (response date July 23, 2026; estimated contract value $600,000; two-year term with three optional one-year renewals); Benton County's urinalysis testing services solicitation (response date July 7, 2026); and the Texas Comptroller's IFB 304T-27-175A1.1 for forensic laboratory supplies including DNA analyzers and direct ELISA kits for controlled-substance screening (response date October 20, 2026). The mismatch between the code's nominal scope and the work actually being bought suggests this code may not represent a reliable signal for leukocyte peroxidase testing procurement activity in state and local markets.
