UNSPSC 41141826: Porphobilinogen

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

UNSPSC 41141826 Porphobilinogen, a Commodity code, does not align with the state and local procurement activity tagged under it. The recent opportunities instead reflect solicitations for laboratory consumables, reagents, standards, and diagnostic supplies used in public health testing — including drug testing supplies, foodborne pathogen detection kits, wastewater surveillance panels, culture media, solid-phase extraction disks, chromatography standards, and whole genome sequencing reagents. State and local issuing bodies posting under this code span state health departments, county public health laboratories, county purchasing offices, municipal procurement bureaus, and university health science centers. The Texas Health and Human Services Commission (HHSC) on behalf of the Department of State Health Services (DSHS) appears as a repeat buyer of laboratory consumables and reagent kits, posting multiple IFBs for food and water testing supplies, respiratory pathogen detection kits, culture media, chromatography standards, and SPE disks. The Mississippi State Department of Health has issued sole-source procurements for Illumina and Clear Labs reagent bundles supporting whole genome sequencing operations. Gwinnett County, Georgia and the City of Philadelphia have posted smaller-value solicitations for drug testing supplies and extraction columns respectively. The University of Texas Health Science Center at San Antonio (UTHSA) issued an RFP for a comprehensive biotech research and clinical diagnostics catalog covering antibodies, genomics reagents, immunoassay kits, and spectroscopy equipment.

Geographic activity concentrates in Texas, Mississippi, Georgia, and Pennsylvania, with Texas showing the highest recent volume. Representative opportunities include the Texas HHSC IFB HHS0017881 for lab supplies compatible with Biomerieux instruments (posted August 19, 2026, responses due August 26, 2026) with a FY2025 historical value between $25,000 and $50,000; the Mississippi State Department of Health sole-source procurement for Illumina WGS kits and reagents (posted April 28, 2026, objections deadline May 14, 2026) totaling $393,667.98; the Texas HHSC IFB HHS0017132 for R&F brand culture media for E. coli and Listeria detection (posted June 2, 2026, responses due June 2, 2026) with a FY2026 historical value of $187,340.00; and the UTHSA RFP 745-26-P19 for a biotech research and clinical diagnostics catalog (posted May 7, 2026, proposals due June 4, 2026) with approximately 8,768 line items ordered in the prior calendar year. Sole-source and brand-specific procurements are common under this code, reflecting infrastructure lock-in and instrument-compatibility requirements.
