UNSPSC 41181555: Prothrombin immunological test system

In this classification, a Prothrombin immunological test system is a device that consists of the reagents used to identify by immunochemical techniques Prothrombin. US FDA regulates Prothrombin immunological test system under 21 CFR 866.5735 and under FDA product code DDF.

UNSPSC 41181555 Prothrombin immunological test system (Commodity) does not map cleanly to recent state and local procurement activity. The code nominally describes a specific clinical laboratory test reagent or kit for prothrombin time (PT) assays, but the recent opportunities tagged under this code cover a much broader range of laboratory services, equipment, and infrastructure — from full-service phlebotomy and specimen handling to equipment repair, test boards, and lab information management systems. Marion County, Oregon's ITB SO1814-26 (due July 24, 2026) solicits comprehensive laboratory testing services and phlebotomy for adults in custody, encompassing specimen collection supplies, courier services, and test reporting rather than prothrombin kits alone. The Texas Department of State Health Services' IFB HHS0017421 (due July 6, 2026) seeks annual repair and maintenance for five pieces of specialized laboratory equipment, including sterilization units and steam generators, with historical annual costs of $25,050 to $40,000. The City of Tampa's RFQ 26-P-00372 (due June 12, 2026) requests a single Heck DR4900 Spectrophotometer as a direct replacement at the McKay Bay Waste to Energy facility. Lubbock Power & Light's RFP 713126ELD (due July 22, 2026) requires annual insulating oil testing and laboratory services across approximately 20 substations, with ISO/IEC 17025 accreditation and advanced data integration capabilities. These solicitations reveal that state and local jurisdictions tag work under this commodity code that spans equipment procurement, maintenance contracting, and complex analytical services—not the narrow reagent or test-kit focus the code name suggests.

Issuing bodies include county detention facilities (Marion County, Oregon), state health departments (Texas DSHS), municipal utilities (Lubbock Power & Light, City of Tampa), transit authorities (Broward County Transportation), and special districts. Geographic spread across recent opportunities includes Oregon, Texas, Florida, Connecticut, and California. The mismatch between code taxonomy and actual procurement scope makes this code a low-clarity indicator for business development targeting: vendors pursuing prothrombin reagents or test kits will find limited relevance in the recent activity, while firms offering laboratory services infrastructure, equipment maintenance, or analytical testing may find opportunities clustered in utilities, water treatment, health agencies, and municipal departments, though the Commodity coding here does not reliably signal their presence.
