UNSPSC 41142058 Total thyroxine test system is a Commodity code that in current state and local procurement activity spans forensic drug and toxicology testing reagents, certified reference materials, and laboratory analytical equipment used by public safety, health, and law enforcement agencies for evidentiary analysis and method validation. The code sees solicitation activity from state departments (public safety, health services, criminal justice) and county forensic laboratories, with work ranging from direct ELISA immunoassay reagent kits for controlled-substance screening to certified drug reference standards meeting ISO/IEC 17025 accreditation and mass spectrometry equipment for chemical identification. Quantities are typically modest—ranging from 3 to 30 units per line item for reagent kits, up to 131 line items of certified reference standards per procurement—and delivery cycles are short, often measured in weeks to months.
