UNSPSC 42181548: IVD reagents

Reagents used for other tests

UNSPSC 42181548 Commodity IVD reagents encompasses in vitro diagnostic reagents and related laboratory consumables state and local health departments, forensic laboratories, clinical centers, and county correction departments procure to support specimen analysis, proficiency testing, drug screening, and disease detection workflows. Recent solicitations show state and local buyers using this code to source proficiency testing materials, drug screening panels, PCR assays, immunoassay supplies, and reference standards for laboratory operations ranging from municipal water testing to criminal justice toxicology and clinical employee health screening. The issuing bodies span county departments of corrections and health services, municipal water utilities, university research facilities, and hospital systems, with particularly active procurement from Texas counties (Collin, Denton, Harris) and Florida municipalities.

Recent activity includes Collin County Community Supervision and Corrections Department's RFP for offender specimen collection and drug testing services with proposals due July 23, 2026, specifying immunoassay screening with LC/MS/MS or GC/MS confirmation, immunology proficiency testing samples solicited by University of Wisconsin-Madison (bids due June 19, 2026 for partial rebid under 2026-UWMSN-01335-RFB), and Harris Center for Mental Health and IDD's solicitation for clinical laboratory services including drug screening and disease panels with responses due June 17, 2026. Santa Monica's Water Resources Division issued an ITB for microbial source tracking using PCR assays (due June 9, 2026), and Meriden, Connecticut's Water Department solicited two-year laboratory testing services covering 56 frequent parameters plus infrequent PFAS and asbestos testing (due June 12, 2026). Geographic concentration is strongest in Texas and Florida, with secondary activity in California, Connecticut, and Wisconsin; the recent opportunities reflect ongoing demand from corrections, public health, clinical, and environmental compliance programs rather than peak procurement windows.
