UNSPSC 41142056: Thyroxine-binding globulin test system

In this classification, Thyroxine-binding globulin test system connotes a device used to measure Thyroxine-binding globulin levels. US FDA regulates Thyroxine-binding globulin test system under 21 CFR 862.1685 and under FDA product code CEE.

UNSPSC 41142056 Thyroxine-binding globulin test system is a Commodity code, but recent state and local opportunities under this code do not reflect thyroxine-binding globulin testing at all. Instead, the code tags a diverse mix of forensic and clinical laboratory procurement: direct ELISA drug-screening reagent kits, mosquito-borne-illness test systems, certified drug reference standards for toxicology analysis, and DNA screening kits for forensic laboratories. State and local issuing bodies — primarily state health and criminal justice agencies, county forensic laboratories, and state environmental divisions — are using this code to procure diagnostic test systems, reagent kits, and certified reference materials for forensic drug analysis, communicable disease surveillance, and DNA screening. The work involves consumable diagnostic supplies, test equipment, and calibration materials that support chain-of-custody laboratory operations.

Recent activity concentrates in Texas and Florida. The Texas Department of Public Safety posted an IFB on July 9, 2026 (due July 23, 2026) for direct ELISA immunalysis reagent kits for cannabinoids, opiates, PCP, amphetamines, barbiturates, methamphetamine, cocaine, benzodiazepines, oxycodone, carisoprodol, and zolpidem across 12 line items with estimated quantities of 3 to 30 units per item. The Texas Health and Human Services Commission conducted a competitive IFB (HHS0016902v2, closed January 29, 2026) for QIAxcel and QIAamp DNA screening kits with historical spending guidance of $25,050 to $30,000 in fiscal year 2025. Pinellas County, Florida, issued an Invitation to Quote on April 23, 2026 (same-day deadline) for 131 line items of certified drug reference standards meeting ISO/IEC 17025:2017 accreditation, funded through $72,126.85 in Paul Coverdell Forensic Sciences Improvement Act federal funds with approximately $49,034 allocated to equipment and supplies. The Illinois Department of Financial and Professional Regulation established a joint purchase master contract for mosquito testing equipment (RAMP System and test kits) through a sole source to ADAPCO, LLC in May 2026. A separate Texas Department of Criminal Justice emergency procurement (IW248126, April 15, 2026) for mass spectrometer equipment and accessories included HUB subcontracting plan requirements but disclosed no specific commodity details or budget.
