UNSPSC 41181924: Estrogen receptor assays tests

In this classification, a Estrogen receptor assays tumor associated antigen immunological test system that consists of the reagents used to identify by immunochemical techniques Estrogen receptor assays based tumors.

UNSPSC 41181924 Estrogen receptor assays tests (Commodity) represents a narrow and specialized diagnostic testing service with minimal recent state and local procurement activity. The code's nominal scope—laboratory assays measuring estrogen receptor expression or activity—does not align with the diverse testing and equipment procurements actually showing in recent state and local solicitations tagged under it. Marion County, Oregon solicited laboratory testing services and phlebotomy for adults in custody (ITB SO1814-26, due July 24, 2026), but this encompasses general clinical laboratory work and specimen collection rather than estrogen receptor assays. The Texas Department of State Health Services procured repair and maintenance services for laboratory sterilization and washing equipment (IFB HHS0017421, due July 6, 2026), and the City of Tampa sought a spectrophotometer replacement for a waste-to-energy facility (RFQ 26-P-00372, due June 12, 2026)—both tangential to the code's stated commodity. Lubbock Power & Light requested insulating oil testing and laboratory services for electric utility equipment (RFP, due July 22, 2026), and the County of Santa Clara issued an RFI for a lab information management system replacement (RFI RFITSSFY260686, due April 22, 2026), neither of which involve estrogen receptor testing.

The issuing-body mix spans county health and detention operations (Marion County), state health departments (Texas DSHS), municipal utilities (City of Tampa, Lubbock Power & Light), and county public health infrastructure (Santa Clara County), with no repeat buyers under this code. Geographic activity includes Oregon, Texas, Florida, and California. The mismatch between the code's technical definition and the actual procurements flagged under it suggests either coding error in the source data or that UNSPSC 41181924 may be used as a catch-all for laboratory testing and equipment services broadly. Firms pursuing work in clinical diagnostics, water quality testing, or utility laboratory services will find more accurate targeting through Family or Class codes covering laboratory testing more broadly rather than relying on this Commodity code's definition. The narrow posted activity offers limited near-term revenue opportunity under this specific code.
