UNSPSC 41202056: Salmonella spp. serological reagents

In this classification, Salmonella genus serological reagents are devices used in test to identify specific Salmonella genus antibodies in serum. US FDA regulates Salmonella genus serological reagents under 21 CFR 866.3550 and under FDA product code GRL.

UNSPSC 41202056 Salmonella spp. serological reagents is a Commodity code that appears to describe diagnostic serology reagents, but the recent state and local opportunities tagged under this code do not reflect procurement of Salmonella serology products. Instead, the opportunities solicited are primarily HIV, Syphilis, and Hepatitis testing services, laboratory diagnostic testing, forensic analysis, and pool maintenance—work that falls outside the nominal scope of Salmonella serological reagents. The code shows little relevant recent activity aligned with its stated product category, suggesting either a cataloging mismatch in how state and local jurisdictions are tagging opportunities or that Salmonella-specific serological reagent procurement does not track to this code in current state and local practice.

The eight opportunities in the block span Texas counties (Collin County Community Supervision and Corrections Department, Texas Department of Criminal Justice), Illinois state health departments (Illinois Department of Public Health), a Texas city (City of Austin), an Illinois university (University of Houston), and a Florida county (Collier County Board of County Commissioners), posted between February and July 2026. Representative examples include Collin County's RFP 2026-327 for offender specimen collection and drug testing services (RFP, response due July 23, 2026, estimated contract value $600,000), City of Austin IFB 9100AAM1023 for rapid HIV test kits (IFB, response due July 17, 2026), and Illinois Department of Public Health IFB for Hepatitis, HIV, and Syphilis screening assays and instrumentation (IFB, response due March 16, 2026, five-year term with up to five renewal years). The geographic spread concentrates in Texas and Illinois, with one opportunity each from Florida and one multi-state entity. Given the categorical misalignment, vendors should verify whether Salmonella serology is actually being procured under this code or whether a different UNSPSC code better captures the immunoassay and diagnostic serology work appearing in current solicitations.
