UNSPSC 41181931: Nuclear matrix protein 22 tests

In this classification, a Nuclear matrix protein 22 tumor associated antigen immunological test system that consists of the reagents used to identify by immunochemical techniques Nuclear matrix protein 22 based tumors.

UNSPSC 41181931 Nuclear matrix protein 22 tests is a Commodity code that encompasses laboratory diagnostic testing services for specific medical assays, including specimen collection, courier services, test analysis, and phlebotomy support. State and local opportunities under this code reflect a narrow band of activity centered on clinical laboratory services for custody and detention populations, utility-scale equipment diagnostics, and specialized testing infrastructure for municipal and utility operations. The issuing bodies span county health and detention services, state health departments, municipal utilities, and special-purpose districts. Recent solicitations show Marion County, Oregon (ITB SO1814-26, phlebotomy and laboratory testing for Adults in Custody, due July 24, 2026) and the Texas Department of State Health Services (IFB HHS0017421, laboratory equipment repair and maintenance at the South Texas Laboratory in Harlingen, due July 6, 2026), alongside non-aligned opportunities in meter testing systems, water treatment infrastructure, and charger maintenance that appear to be mislabeled under this code rather than reflecting genuine demand for nuclear matrix protein assays.

Geographic activity concentrates in Texas, Florida, and Oregon, with scattered activity in Connecticut and other states. The source shows no coherent pattern of procurement under the actual code definition—only one opportunity (Marion County's laboratory testing and phlebotomy services) aligns with clinical diagnostic testing, while remaining solicitations address laboratory equipment repair, three-phase meter testing, water well construction, ChargePoint charger maintenance, materials testing for fire station construction, and LIMS platform replacement. The code shows minimal recent activity directly targeting nuclear matrix protein 22 assays, making pursuit of this code problematic without further clarity from procurement offices on how they are classifying clinical laboratory services against UNSPSC taxonomy.
