UNSPSC 41181906: Cancer antigen 125 tests

In this classification, a Cancer antigen 125 tumor associated antigen immunological test system that consists of the reagents used to identify by immunochemical techniques Cancer antigen 125 based tumors.

UNSPSC 41181906 Cancer antigen 125 tests is a Commodity code that does not map to the state and local procurement opportunities present in the recent activity record. The source contains fourteen recent solicitations spanning laboratory testing services, equipment repair and maintenance, spectrophotometer procurement, transformer oil analysis, landscape architectural services, facility system support, electrical meter testing boards, water treatment plant construction, fatigue testing systems, and lock-in amplifier equipment. None of these opportunities involve cancer antigen 125 (CA 125) testing, immunoassay reagents, or oncology-related laboratory diagnostics. The mismatch between the code's stated scope and the actual work posted under the code tag indicates either a data classification error or minimal recent procurement activity aligned with CA 125 testing per se.

The recent opportunities do reveal consistent state and local demand for laboratory services broadly defined — specimen collection, courier pickup, test reporting, equipment maintenance, and data integration — across multiple jurisdictions including Marion County (Oregon), the Texas Department of State Health Services, the City of Tampa, Lubbock Power & Light, and the County of Santa Clara. However, none of these procurements specifically target cancer antigen 125 assays or related tumor marker testing. Pursuit under this code should be deferred pending clarification of whether solicitations will be retagged with the correct UNSPSC commodity code or whether CA 125 testing demand exists in state and local volume but remains untagged in current public notices.
