UNSPSC 41131713: Glutathione reductase assay

In this classification a glutathione reductase assay is a device used to determine the activity of the enzyme glutathione reductase in serum, plasma, or erythrocytes by such techniques as fluorescence and photometry. The results of this assay are used in the diagnosis of liver disease, glutathione reductase deficiency, or riboflavin deficiency US FDA regulates Glutathione reductase assay under 21 CFR 864.7375 and under FDA product code KQF.

UNSPSC 41131713 Glutathione reductase assay is a Commodity code that does not align with recent state and local procurement activity in the source material. The code nominally describes a specific enzymatic assay used in clinical laboratory diagnostics, but the state and local opportunities posted under or near this classification span drug testing, specimen collection, toxicology screening, employment physicals, forensic analysis, and breath alcohol testing equipment — none of which involve glutathione reductase assays. The recent opportunities show state and local governments buying broad-spectrum drug screening services (immunoassay and confirmatory testing via LC/MS/MS or GC/MS), urinalysis panels, employment screening bundles, forensic drug standards for seized-drug analysis, clozapine assay kits for psychiatric monitoring, naloxone and drug deactivation systems, and breath alcohol devices. The issuing bodies are counties (Collin County, Texas; Seminole County, Florida; Benton County, Oregon; Pinellas County, Florida; Clay County, Florida; Collier County, Florida), the State of Oregon, the State of Nevada, and a municipal college system (City Colleges of Chicago).

The geographic spread covers Texas, Florida, Oregon, and Nevada, with the densest recent activity in Florida (Seminole, Pinellas, Clay, and Collier counties). The code shows no recent opportunities for glutathione reductase assays specifically. Representative posted solicitations include Collin County Community Supervision and Corrections Department's RFP 2026-327 for offender specimen collection and drug testing services (due July 23, 2026, estimated contract value $600,000 over two years plus three optional renewals); Benton County, Oregon's RFP for urinalysis testing supporting its Family Treatment Court Program (due July 7, 2026); Pinellas County, Florida's Invitation to Quote for certified drug standards for forensic analysis under the Paul Coverdell Forensic Sciences Improvement Act Program (due April 23, 2026, funded at $72,126.85 with approximately $49,034.00 designated for equipment and supplies); and Nevada's formal competitive bid for Intoxilyzer 9000 devices and printers (due February 17, 2026 and February 12, 2026). The mismatch between the code name and actual procurement activity suggests either miscoding by the issuing bodies or that this Commodity code is not in active use for state and local contracts currently.
