UNSPSC 41202047 Proteus spp. (weil-felix) serological reagents is a Commodity code that in practice spans diagnostic testing supplies and services far broader than its nominal scope — state and local governments are currently using it to procure HIV test kits, sexually transmitted infection (STI) testing reagents and confirmation supplies, drug screening test kits and analyzer consumables, and syphilis reagents. The issuing bodies include state departments of public health (Illinois Department of Public Health), county departments and sheriff's offices (Collin County Community Supervision and Corrections Department, Collin County Health Care Services, Gwinnett County), municipal public health programs (City of Austin), and state criminal justice agencies (Texas Department of Criminal Justice). Illinois Department of Public Health and Collin County appear as repeat buyers. Work solicited ranges from one-time-use rapid test kits for point-of-care deployment to high-volume reagent supplies supporting automated analyzer platforms, from drug-testing immunoassay screening with confirmation instrumentation to laboratory services integrating multiple test types and specimen handling.

Geographic activity centers on Texas and Illinois, with recent solicitations from Texas (Collin County, Gwinnett County, Texas Department of Criminal Justice), Illinois (Illinois Department of Public Health), and scattered municipal activity (City of Austin). Representative recent opportunities include the Illinois Department of Public Health's change order (IFB) increasing Hologic NG/NT test kit and collection kit volumes from 15,000 to 25,000 tests annually and collection kits from 15,000 to 30,000 annually under a five-year contract with a revised total cost of $900,000 (response due October 13, 2026); Collin County Community Supervision and Corrections Department's RFP for offender specimen collection and drug testing services covering approximately 25,031 annual tests with staffing at two sites in Plano and McKinney, estimated contract value $600,000, two-year term with optional renewals (responses due July 23, 2026); and the City of Austin's IFB for one-time-use rapid HIV Type 1 and Type 2 test kits (Abbott Determine HIV 1/2 Ag/Ab Combo) with estimated annual volumes of 375 test kits and 79 control kits (response due September 3, 2026 for the rebid, originally July 17, 2026). Illinois Department of Public Health also issued an emergency sole-source procurement to Abbott Laboratories for HIV and Syphilis reagents, calibrators, controls, and maintenance services totaling $38,079.50 (August 18, 2026).
