UNSPSC 41141800: Clinical chemistry substrates

UNSPSC 41141800 Clinical chemistry substrates is a Class code covering laboratory reagents, test kits, extraction disks, culture media, and consumable analytical supplies that state and local public health laboratories, university health systems, and county health departments procure for food safety testing, drinking water compliance, wastewater surveillance, and diagnostic microbiology. The work being solicited ranges from drug testing kits for abuse analyzers to EPA-approved reagents for coliform and E. coli detection, whole genome sequencing consumables for pathogen surveillance, and culture media for detecting foodborne pathogens such as Listeria and Salmonella. Issuing bodies include state health departments, county health authorities, municipal laboratories, and university health science centers; Texas Department of State Health Services (DSHS) and Mississippi State Department of Health appear as repeat active buyers, each with multiple procurements posted in the past six months. Gwinnett County, Georgia; the City of Philadelphia; and the University of Texas Health Science Center at San Antonio have also recently solicited under or near this code.

The code sees the strongest recent activity in Texas and Mississippi, with secondary activity in Georgia and Pennsylvania. Representative recent opportunities include the Texas HHSC's IFB HHS0017881 (posted August 19, 2026, due August 26, 2026) for lab supplies and quality control materials compatible with Biomerieux instruments for food, water, dairy, and shellfish testing, with a prior-year guideline value of $25,000 to $50,000; the Mississippi State Department of Health's sole-source procurement for Illumina whole genome sequencing reagent kits and MiSeq consumables (objection deadline May 14, 2026, total estimated cost $393,667.98); the Texas HHSC's IFB HHS0017132 (posted June 2, 2026, due June 2, 2026) for R&F culture media kits for E. coli O157:H7 and Listeria detection, with FY2026 historical value of $187,340.00; and Gwinnett County's RFP BL144-26 (posted September 23, 2026, due October 14, 2026) for drug testing supplies compatible with a drugs of abuse analyzer on an annual contract basis. Procurement vehicles include competitive IFBs, RFPs, sole-source notices with objection periods, and micro-purchases; contract terms typically run one year with optional annual renewals, and awards are made on best-value criteria rather than lowest price alone.
