UNSPSC 41181503: Human allotypic marker immunological test system

In this classification, a Human allotypic marker immunological test system is a device that consists of the reagents used to identify by immunochemical techniques Human allotypic marker. US FDA regulates Human allotypic marker immunological test system under 21 CFR 866.5065 and under FDA product code DHF.

UNSPSC 41181503 Human allotypic marker immunological test system is a Commodity code. State and local procurement activity under this code diverges sharply from the code's nominal scope. The recent opportunities posted under this code include optical surface profilers for precision optics education, airfield photometric testing systems, nanoindenter equipment for materials testing, three-phase meter test boards for electric utility metering programs, precision high-voltage capacitance measurement modules, atmospheric monitoring instruments for gas detection at water facilities, laboratory equipment repair and maintenance contracts, spectrophotometers for waste-to-energy facilities, oil testing laboratory services for transformer analysis, and sole-source software licenses for drug discovery research and process instrumentation. None of these procurements involve human allotypic marker testing or immunological test systems as the code name suggests. The actual buying across these opportunities centers on specialized laboratory, testing, and analytical equipment for utilities, educational institutions, and environmental monitoring rather than immunological diagnostics. Issuing bodies include city utilities (Tampa, Phoenix, Ocala, Kissimmee), county authorities (Lee County, Collier County, Marion County), state universities (Jackson State, Texas State, Texas A&M), a state health department (Texas DSHS), a junior college (Valencia College), and a state patrol agency (Colorado). The mix reflects education, municipal water and wastewater operations, electric utility infrastructure, and environmental compliance as primary drivers.

Recent activity concentrates in Florida, Texas, Colorado, Oregon, and Arizona. Representative solicitations include Lee County Port Authority requesting airfield photometric testing under RFQ 2026115BW due October 29, 2026; the City of Ocala Electric Utility issuing RFP ELE/260570 for a three-phase meter test board system with sealed proposals due April 30, 2026; Valencia College posting Notice of Intended Sole Source SS202635 for a PGI Optics CORE optical surface profilometer on October 19, 2026; Kissimmee Utility Authority requesting bids under IFB 26046JG for an OMICRON CP TD12 high-voltage testing module due September 22, 2026; and Jackson State University twice posting sole-source notices (SSP26-03 and RFX 3150007041) for five-year Schrodinger drug discovery software licenses at $65,318.25 total cost, with objection periods closed October 13, 2026. The code shows substantial recent activity but little alignment with immunological testing; business development professionals should treat this code's recent opportunities as a data-quality signal rather than a reliable UNSPSC classification for immunological work.
