UNSPSC 41202000: Serological reagents

In this classification, these entries connote the reagents used in association with serological laboratory procedures.

UNSPSC 41202000 Serological reagents is a Class code encompassing blood-based diagnostic testing supplies and related laboratory services that state and local governments procure for public health, criminal justice, and higher-education clinical operations. State and local buyers under this code are purchasing immunoassay screening kits, confirmatory reagents, calibrators, and control materials for infectious disease testing (HIV, Syphilis, Hepatitis B and C), along with associated lab instrumentation, maintenance, and testing services. Recent solicitations show issuing bodies including county probation and corrections departments (Collin County Community Supervision and Corrections Department), city health departments (City of Austin), state departments of public health (Illinois Department of Public Health), state criminal justice agencies (Texas Department of Criminal Justice), and higher-education institutions (University of Houston). The Illinois Department of Public Health appears as a repeat buyer, with multiple procurements for HIV and Syphilis reagents and instrumentation over a six-month window.

Geographic concentration is visible in Texas and Illinois, with Collin County (Texas), the City of Austin (Texas), the Texas Department of Criminal Justice, the Illinois Department of Public Health (Carbondale and Jackson County locations), and the University of Houston dominating recent activity. Representative opportunities include Collin County's RFP 2026-327 (Offender Specimen Collection and Drug Testing Services, due July 23, 2026, $600,000 estimated annual value) soliciting immunoassay screening and LC/MS/MS confirmation across two collection sites; the City of Austin's IFB 9100AAM1023 (HIV Test Kits, due July 17, 2026) seeking Abbott Determine rapid HIV test kits on an all-inclusive per-unit basis; and the Illinois Department of Public Health's IFB 26482DPHOFCDIB50489 (Hepatitis/HIV/Syphilis 4th Gen Assay Screening and Instrument, due March 16, 2026) establishing a five-year fully automated combination screening platform with estimated annual test volumes exceeding 30,000 tests. An earlier emergency procurement by Illinois Department of Public Health awarded Abbott Laboratories sole-source status at $38,079.50 for proprietary HIV and Syphilis reagents and maintenance services, indicating that specialty instrumentation requirements frequently drive single-vendor outcomes.
