UNSPSC 41131703: Red blood cell enzyme assay

In this classification a red blood cell enzyme assay is a device used to measure the activity in red blood cells of clinically important enzymatic reactions and their products, such as pyruvate kinase or 2,3-diphosphoglycerate US FDA regulates Red blood cell enzyme assay under 21 CFR 864.7100 and under FDA product code LKZ.

UNSPSC 41131703 Red blood cell enzyme assay, a Commodity code, does not align with the actual procurement activity state and local governments are conducting under this classification. The recent opportunities posted under this code span drug and substance testing services, occupational health screenings, laboratory diagnostics, and forensic analysis — none of which involve red blood cell enzyme assays as a standalone product or service line. Collin County Community Supervision and Corrections Department is soliciting offender specimen collection and drug testing services under RFP 2026-327 (response due July 23, 2026, estimated value $600,000), covering immunoassay screening with LC/MS/MS or GC/MS confirmation across approximately 25,031 annual tests. Gwinnett County, Georgia is requesting proposals for drug testing supplies compatible with a drugs of abuse analyzer (due October 14, 2026). Benton County, Oregon is seeking urinalysis testing services for its Family Treatment Court Program (due July 7, 2026) with twice-weekly testing, confirmatory panels, and web-based reporting. The State of Oregon issued a sole source procurement for Clozapine Assay Kits and controls from Saladax Biomedical (May 2026), and Pinellas County, Florida procured certified drug reference standards for forensic toxicology and seized drug analysis (April 2026, Paul Coverdell Act funded). The code shows no clear market for red blood cell enzyme assays and likely reflects a data-classification error rather than active demand.

The geographic spread of recent activity spans Texas (Collin County), Georgia, Oregon, Florida, and North Carolina (Charlotte), with the most detailed solicitations emphasizing CLIA-certified laboratories, immunoassay and confirmatory testing methodologies, and multi-panel drug screening protocols. The issuing bodies include county criminal justice and corrections departments, county health services, municipalities, and state agencies. No representatives of this code's nominal scope appear in recent state and local postings — the taxonomy entry does not match buying behavior. Business development professionals evaluating this code should verify with procurement offices whether the classification is correct before pursuing opportunities listed under it.
