UNSPSC 41131905: Occult blood test

In this classification, Occult blood test connotes a device used to detect occult blood in urine or feces. Occult blood is blood present in such small quantities that it can be detected only by chemical tests of suspected material, or by microscopic or spectroscopic examination. US FDA regulates Occult blood test under 21 CFR 864.6550 and under FDA product code OOX.

UNSPSC 41131905 Occult blood test is a Commodity code capturing laboratory equipment, consumables, and proficiency testing samples that state and local health agencies and educational institutions procure to support hematology, hemoglobin analysis, and blood screening programs. Recent solicitations show state and local buyers purchasing ion-exchange HPLC analyzers for HbA1c and fetal hemoglobin screening, ICP-MS instrument consumables for pediatric blood lead analysis, and custom-manufactured proficiency testing samples for quality assurance in hematology workflows. The issuing bodies span state health departments (Texas Health and Human Services Commission and Department of State Health Services) and university laboratory systems (University of Wisconsin-Madison), reflecting procurement across both public health agencies and academic research institutions that operate clinical and diagnostic laboratories.

Texas dominates recent activity under this code, with the Texas Health and Human Services Commission (HHSC) posting multiple IFBs in the March–May 2026 window, including HHS0017310 for a D-10 Hemoglobin Testing System with Rack Loader at the South Texas Lab in Harlingen (response deadline May 18, 2026) and HHS0017071 for PerkinElmer ICP-MS consumables and supplies for blood lead screening (response deadline March 5, 2026, with historical spend guidance of $20,000 to $30,000). University of Wisconsin-Madison posted a competitive bid (2026UWMSN01287RFB) on April 3, 2026 for custom-made Hematology/Whole Blood Chemistry proficiency testing samples (response deadline May 5, 2026), illustrating academic procurement activity in the upper Midwest. Firm and fixed pricing, best-value evaluation criteria, and compliance with state-specific statutory requirements (including suspension and debarment certification and cybersecurity controls) characterize these procurements; no set-aside designations for disadvantaged enterprises are specified in the recent opportunities.
