UNSPSC 41181916: Cancer associated serum antigen tests

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

UNSPSC 41181916 Cancer associated serum antigen tests is a Commodity code that state and local governments procure primarily as part of broader laboratory testing service contracts for clinical and diagnostic screening, not as standalone serum antigen kits or reagents. Recent solicitations show public health labs, corrections departments, and municipal utilities buying laboratory testing services that include antigen analysis alongside broader specimen handling, phlebotomy, equipment maintenance, and data management. Marion County, Oregon issued an ITB on July 10, 2026 for Laboratory Testing Service and Phlebotomy (SO1814-26, due July 24, 2026) encompassing laboratory testing, specimen collection, courier services, and phlebotomist draws for Adults in Custody. The Texas Department of State Health Services issued an IFB on June 29, 2026 for Laboratory Equipment Repair and Maintenance (HHS0017421, due July 6, 2026) covering preventive maintenance, inspections, and 24-hour technical support for five pieces of equipment at its South Texas Laboratory in Harlingen, with a historical annual range of $25,050 to $40,000. Lubbock Power & Light issued an RFP on June 18, 2026 for annual insulating oil testing and laboratory services (713126ELD, due July 22, 2026) requiring ISO/IEC 17025 accreditation, five years of electric utility experience, and automated lab information management systems compatible with transformer oil diagnostics per IEEE C57.104 and IEC methodologies across approximately 20 substations.

Activity under this code concentrates in Texas and Florida, with additional procurement in Oregon and Connecticut. County public health departments, municipal utilities managing electrical equipment, state health agencies, and municipal corrections operations drive the most recent solicitations. The issuing bodies span state health departments, county government, municipal utilities, and independent jurisdictions rather than school districts or transit authorities. Aside from the Marion County corrections testing contract and the Lubbock utility lab services RFP—both of which incorporate serum or fluid antigen and diagnostic analysis—most other recent opportunities tagged to this code (including three-phase meter test boards, fire station construction materials testing, water well drilling, and charger maintenance) show no meaningful connection to cancer-associated serum antigen testing, suggesting misclassification in the state procurement databases where these opportunities are tagged.
