UNSPSC 41181909: Cancer antigen 19-9 tests

In this classification, a Cancer antigen 19-9 tumor associated antigen immunological test system that consists of the reagents used to identify by immunochemical techniques Cancer antigen 19-9 based tumors.

UNSPSC 41181909 Cancer antigen 19-9 tests is a Commodity code, but the recent opportunities posted under it do not reflect diagnostic laboratory testing for oncology markers. Instead, the source documents a scattered mix of unrelated state and local procurements — laboratory equipment repair and maintenance, water system testing, electrical equipment diagnostics, and facility construction materials inspection — none of which align with cancer antigen 19-9 assays or tumor marker analysis. The one solicitation with plausible relevance, Marion County, Oregon's laboratory testing service for adults in custody (ITB SO1814-26, due July 24, 2026), encompasses general testing and phlebotomy but does not specify oncology panels or CA 19-9 assays. The code shows little recent activity in cancer antigen testing procurement, and the opportunities captured appear to reflect miscoding rather than legitimate demand under this Commodity code.

Because the source does not support any material state and local procurement activity for cancer antigen 19-9 tests, evaluation of geographic concentration, issuing-body mix, and market pursuit is not warranted.
