UNSPSC 41131716: Carboxyhemoglobin assay

In this classification a carboxyhemoglobin assay is a device used to determine the carboxyhemoglobin (the compound formed when hemoglobin is exposed to carbon monoxide) content of human blood as an aid in the diagnosis of carbon monoxide poisoning. This measurement may be made using methods such as spectroscopy, colorimetry, spectrophotometry, and gasometry US FDA regulates Carboxyhemoglobin assay under 21 CFR 864.7425 and under FDA product code LGL.

UNSPSC 41131716 Carboxyhemoglobin assay is a Commodity code that in state and local procurement activity covers drug testing supplies, laboratory consumables, and specimen-collection services for criminal justice, occupational health, and public-health screening programs. State and local agencies are not procuring carboxyhemoglobin testing specifically under this code; instead, they are soliciting broader drug-screening, urinalysis, and forensic laboratory services that incorporate immunoassay, confirmatory testing (LC/MS/MS, GC/MS), and alternative methodologies including oral fluid and hair analysis. Issuing bodies include county community supervision departments, county health services, cities, counties, state agencies, and universities. Collin County Community Supervision and Corrections Department (Texas) appears in the recent record more than once, indicating repeat procurement activity in criminal-justice testing.

Recent opportunities span Texas, Georgia, Florida, North Carolina, Oregon, and Wisconsin. Collin County, Texas, is soliciting offender specimen collection and drug testing services through RFP 2026-327 with a July 23, 2026 response date and an estimated contract value of $600,000 for approximately 25,031 annual tests across five-panel and six-panel screens, with lab certification required from SAMHSA, Texas Department of Public Safety, or CAP. Gwinnett County, Georgia, is requesting proposals for drug-testing supplies compatible with an existing drugs-of-abuse analyzer (RFQ, October 14, 2026 due date). Benton County, Oregon, is procuring urinalysis testing services for a family treatment court program through an RFP due July 7, 2026, requiring CLIA certification and twice-weekly testing with 48- to 72-hour turnaround. The Texas Comptroller of Public Accounts issued IFB 304T-27-175A1.1 on September 23, 2026 (due October 20, 2026) for proprietary laboratory consumables and reagents covering DNA analysis and drug-screening components from specified manufacturers including Life Technologies, Promega, Qiagen, and Abbott, serving Texas Department of Public Safety and Texas Department of Parks and Wildlife statewide. The code shows active, multi-jurisdictional procurement activity concentrated in high-volume testing environments where vendor qualification, certification, and performance reporting capability are primary evaluation drivers.
