NIGP 11505: Biochemical Reagents and Tests: Antibiotic Assays, Differentiation Discs, etc.

NIGP 11505 Biochemical Reagents and Tests: Antibiotic Assays, Differentiation Discs, Etc., an Item code, represents the procurement of culture media, stains, antimicrobial susceptibility testing discs, diagnostic assays, reagents, controls, and related consumables by state and local public health laboratories, county health departments, university research and diagnostic facilities, and corrections agencies. State and local governments buy under this code primarily for clinical microbiology testing (bacterial identification and antibiotic resistance profiling), newborn screening programs, sexually transmitted infection detection, arbovirus surveillance, water quality microbiology, and offender drug testing—all applications requiring validated reagent systems, specialized media, and confirmatory assay kits. The issuing-body mix includes state public health laboratories (Florida Department of Health Bureau of Public Health Laboratories, California Department of Food and Agriculture), county health departments and corrections agencies (San Bernardino County Department of Public Health, Collin County Community Supervision and Corrections Department), and university institutions (University of Southern Mississippi, University of Wisconsin-Madison). Florida Department of Health appears as a repeat buyer across multiple single-source procurements for HIV confirmatory systems, newborn screening reagents, arbovirus testing supplies, and water microbiology reagents, indicating sustained and specialized demand within public health laboratory operations.

Recent activity clusters in California and Florida, with secondary activity in Texas, Illinois, Mississippi, and the District of Columbia. Representative recent opportunities include San Bernardino County Department of Public Health's ITB for laboratory supplies (culture media, stains, reagents, antimicrobial susceptibility disks, and diagnostic test materials) posted July 15, 2026, due July 31, 2026, with a five-year pricing agreement and Net 60 payment terms; Collin County Community Supervision and Corrections Department's RFP for offender specimen collection and drug testing services at $600,000 estimated value, posted July 9, 2026, due July 23, 2026, involving immunoassay screening with LC/MS/MS or GC/MS confirmation across two staffed collection sites; Florida Department of Health's single-source procurement for Bio-Rad Laboratories Geenius System assays, controls, and Sickle Cell kits at $460,000 estimated value, posted July 9, 2026, due July 14, 2026; and California Department of Food and Agriculture's RFQ for plant virus detection reagent sets, AgriStrip test kits, and extraction equipment on a three-year term, posted July 1, 2026, due July 21, 2026. Single-source procurements dominate the code, driven by FDA approval exclusivity, validated in-house testing protocols, and sole-source manufacturer relationships (Bio-Rad, Sebia, Hologic, IDEXX, InBios). Contract values range from $44,000 to $2.7 million, with most running one to three years and including strict compliance requirements for SAMHSA certification, CAP lab accreditation, or equivalent state-level standards.
