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 covering laboratory supplies, reagents, and diagnostic testing systems that state and local public health departments procure to support ongoing clinical and epidemiological laboratory operations. State and local buyers under this code include public health departments and health and human services commissions at the state level, soliciting culture media, reagents, hemoglobin testing systems, and related consumables necessary for blood analysis and screening protocols. Work solicited ranges from routine laboratory media and reagent supplies on an itemized, unit-price basis to specialized diagnostic equipment such as ion-exchange HPLC hemoglobin analyzers. The procurement structure varies from small consumables orders to equipment replacement, with contracts typically establishing ongoing supply relationships with potential renewal or extension options. Quality and performance specifications are detailed and rigorous, reflecting compatibility requirements with existing laboratory infrastructure and clinical protocols.

Recent activity centers on California and Texas. The California Department of Public Health posted RFB-IS-27200117-1 for public health laboratory supplies and media (response due September 4, 2026), with set-asides and preferences for certified small businesses, minority-owned enterprises, women-owned businesses, and disabled veteran-owned businesses under California procurement regulations. The Texas Health and Human Services Commission and Department of State Health Services issued IFB HHS0017310 for a D-10 Hemoglobin Testing System with Rack Loader at the South Texas Lab in Harlingen (response deadline May 18, 2026), with evaluation based on bidder qualifications, performance capability, and price. Texas historical spending for similar goods in fiscal year 2025 ranged from $45,050 to $80,000. Neither solicitation carries federal set-asides, though Texas encourages HUB subcontracting plans and California applies its state-level business enterprise preferences.
