UNSPSC 41141831: Total porphyrine

In this classification, this entry connotes a substrate made of Total porphyrin that is used in clinical chemistry testing.

UNSPSC 41141831 Total porphyrine is a Commodity code that encompasses laboratory reagents, test kits, and specialized consumables used by state health departments and local government laboratories for disease detection, water quality testing, and pathogen surveillance. State and local governments buy these items directly—they include drug-testing supplies compatible with existing analyzer instruments, EPA and FDA-approved reagents for coliform and E. coli detection in drinking water, whole genome sequencing kits for pathogen identification, culture media for foodborne illness detection, and solid-phase extraction disks for pesticide and contaminant analysis in water samples. The issuing bodies span state health departments (Texas Health and Human Services Commission, Mississippi State Department of Health), county health agencies (Gwinnett County, Georgia), and academic medical centers (University of Texas Health Science Center at San Antonio); state health laboratory procurement dominates the recent activity.

The code sees activity concentrated in Texas and Mississippi, with secondary activity in Georgia and Pennsylvania. Representative recent opportunities include the Texas Health and Human Services Commission issuing multiple IFBs for laboratory supplies—food, water, dairy, and shellfish testing consumables due August 26, 2026; respiratory pathogen detection kits for wastewater surveillance with bids due May 19, 2026; and culture media for E. coli O157:H7, Listeria monocytogenes, and Enterobacter detection due June 2, 2026. The Mississippi State Department of Health posted a sole-source procurement for Illumina whole genome sequencing kits (objections due May 14, 2026) and a sole-source notice for Clear Labs sequencing reagents (same deadline). Gwinnett County, Georgia solicited drug-testing supplies compatible with a drugs of abuse analyzer, due October 14, 2026. Historical annual values range from $25,000 to $393,667, with most Texas procurements specifying firm, fixed pricing and best-value evaluation criteria rather than lowest-price award. Pre-bid meetings and industry events are not mentioned in recent solicitations; HUB subcontracting plans are encouraged but not required in Texas procurements.
