UNSPSC 41181520: Complement c3binactivator immunological test system

In this classification, a Complement c3binactivator immunological test system is a device that consists of the reagents used to identify by immunochemical techniques Complement c3binactivator. US FDA regulates Complement c3binactivator immunological test system under 21 CFR 866.5260 and under FDA product code DAC.

UNSPSC 41181520, Complement c3b Inactivator Immunological Test System, is a Commodity code that does not align with the recent state and local contract opportunities posted under this classification. The code nominally describes immunological diagnostic test systems, but the opportunities sourced to it span optical surface profilometry for precision optics instruction, airfield photometric testing systems, drug discovery software platforms, electric meter test boards, high-voltage capacitance measurement modules, laboratory sterilization equipment maintenance, atmospheric gas detection instruments, nanoindentation systems, spectrophotometers for waste-to-energy facilities, transformer oil analysis services, and landscape architectural services — none of which constitute immunological test equipment or complement c3b inactivator assays. The mismatch suggests either systematic miscoding in state and local procurement databases or a collapsed taxonomy that conflates unrelated scientific and technical instrumentation under a shared umbrella.

State and local issuing bodies posting to this code in the period of record include universities (Valencia College in Florida; Jackson State University in Mississippi; Texas State University; Texas A&M University System), municipal utilities (City of Ocala Electric Utility in Florida; Kissimmee Utility Authority in Florida; Lubbock Power & Light in Texas), county governments (Lee County Port Authority, Florida; Collier County, Florida; Marion County, Oregon), city procurement offices (City of Tampa, Florida; City of Phoenix, Arizona; City of Orlando, Florida), state agencies (Texas Department of State Health Services; Colorado State Patrol), and transit or toll authorities (Harris County Toll Road Authority, Texas). Activity concentrates in Florida and Texas, with secondary activity in Colorado, Mississippi, Oregon, and Arizona. Because the code shows no relevant recent immunological testing opportunities and the posted solicitations address entirely distinct equipment and service domains, the code presents no actionable market signal for vendors focused on complement c3b inactivator test systems or related immunological diagnostics.
