UNSPSC 41181557: Retinol-binding protein immunological test system

In this classification, a Retinol-binding protein immunological test system is a device that consists of the reagents used to identify by immunochemical techniques Retinol-binding protein. US FDA regulates Retinol-binding protein immunological test system under 21 CFR 866.5765 and under FDA product code CZS.

UNSPSC 41181557 Retinol-binding protein immunological test system, a Commodity code, does not align with the work state and local governments are actually procuring under this tag. The recent opportunities posted under this code span precision optical and electrical test equipment, laboratory software platforms, airfield lighting systems, spectrophotometry, and water-quality instrumentation—none of which relate to retinol-binding protein analysis or immunological testing. The mismatch suggests either a data-classification error in how opportunities were tagged or a code that is rarely used for its nominal purpose in state and local procurement. No state or local issuing body is currently soliciting retinol-binding protein immunological test systems or related assay kits.

The opportunities actually posted under this code reveal a diverse set of issuing bodies and geographic spread across Florida, Texas, Colorado, Oregon, and other states, with universities (Valencia College, Jackson State University, Texas State University, Texas A&M University System), municipal utilities (City of Ocala, Kissimmee Utility Authority, City of Phoenix, Lubbock Power & Light), county governments (Collier County, Marion County, Lee County Port Authority, Harris County), state agencies (Colorado State Patrol, Texas Department of State Health Services), and transit or port authorities competing for equipment and services. Representative solicitations include Valencia College's sole-source optical surface profilometer procurement (RFQ, October 2026), Lee County Port Authority's airfield photometric testing RFQ (due October 29, 2026), and the City of Ocala Electric Utility's three-phase meter test board RFP (due April 30, 2026). Given the divergence between the code's stated purpose and actual procurement activity, this code warrants reclassification or should be skipped in favor of more precise commodity codes for the equipment categories actually being bought.
