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, a Commodity code, has minimal recent state and local procurement activity aligned with its nominal scope. The recent opportunities tagged with this code predominantly reflect drug testing, specimen collection, and laboratory services procurement rather than glutathione reductase assay kits or reagents specifically. State and local governments soliciting under this code are primarily counties, cities, and specialized public health agencies acquiring broad-spectrum drug and alcohol testing services, urinalysis testing, forensic laboratory supplies, and occupational health screening—work that may incidentally involve enzymatic assays but is not narrowly focused on glutathione reductase measurement.

The issuing bodies include Collin County (Texas) Community Supervision and Corrections Department, Gwinnett County (Georgia), the Texas Comptroller of Public Accounts Statewide Procurement Division, the City of Charlotte (North Carolina), Bernalillo County (New Mexico), Benton County (Oregon), Seminole County (Florida), Pinellas County (Florida), the State of Oregon, and the University of Wisconsin-Madison. Recent solicitations cluster in Texas, Georgia, Florida, North Carolina, and Oregon. Representative opportunities include Collin County's RFP 2026-327 for offender specimen collection and drug testing services (due July 23, 2026, estimated value $600,000), Gwinnett County's drug testing supplies request compatible with an existing drugs of abuse analyzer (due October 14, 2026), the Texas Comptroller's IFB 304T-27-175A1.1 for proprietary chemical laboratory equipment and supplies including cannabinoid and opioid detection kits (due October 20, 2026, serving the Texas Department of Public Safety and Texas Department of Parks and Wildlife), Benton County's urinalysis testing procurement for its Family Treatment Court Program (due July 7, 2026), and Pinellas County's procurement of certified drug reference standards for forensic analysis (due April 23, 2026, funded through the Paul Coverdell Forensic Sciences Improvement Act with $72,126.85 in federal funds). The code shows limited recent activity specifically targeting glutathione reductase assays as a discrete procurement line item.
