UNSPSC 41181913: Cancer antigen 549 tests

In this classification, a Cancer antigen 549 tumor associated antigen immunological test system that consists of the reagents used to identify by immunochemical techniques Cancer antigen 549 based tumors.

UNSPSC 41181913 Cancer antigen 549 tests (Commodity) shows minimal relevant recent state and local procurement activity. The code nominally describes a specific laboratory antigen test; however, the recent opportunities posted under this code span broad laboratory testing services, equipment repair and maintenance, spectrophotometer procurement, insulating oil analysis, landscape architecture, water reclamation system support, electric meter test boards, water well construction, fatigue testing systems, and lock-in amplifiers—none of which align with cancer antigen testing. The mismatch suggests either systematic miscoding of diverse laboratory and technical procurements under this commodity or inconsistent application of the taxonomy by issuing bodies. Of the opportunities reviewed, only the Marion County, Oregon ITB for laboratory testing services and phlebotomy (posted July 10, 2026, due July 24, 2026) includes scope language that could encompass general laboratory testing including potential serology or antigen work, though the solicitation does not specify cancer antigen 549 testing or any oncology-related lab work.

The geographic spread across recent opportunities spans Oregon, Texas, Florida, Connecticut, California, and multiple other states, but this distribution reflects coding inconsistency rather than concentrated demand for cancer antigen 549 tests. Issuing bodies include county health and correctional departments, state health services agencies, municipal utilities, transit authorities, universities, and water treatment districts—a fragmented mix with no clear buyer pattern for this specific test category. No repeat buyers, standing contracts, or volume procurement signals appear in the recent record. State and local procurement professionals should verify correct code assignment with issuing bodies before pursuing opportunities tagged under 41181913, as the current activity does not support a coherent category of cancer antigen testing solicitations.
