UNSPSC 41131906: Osmotic fragility test

In this classification, Osmotic fragility test connotes a device used to determine the resistance of red blood cells to hemolysis (destruction) in varying concentrations of hypotonic saline solutions. US FDA regulates Osmotic fragility test under 21 CFR 864.6600 and under FDA product code GKE.

UNSPSC 41131906 Osmotic fragility test is a Commodity code covering laboratory consumables, reagents, and specialized diagnostic equipment that state and local public health laboratories procure to support ongoing clinical and epidemiological testing operations. State and local governments buy culture media, growth reagents, sterility-validated consumables, and hemoglobin analysis systems under this code to maintain laboratory accreditation standards and meet technical performance specifications for blood screening, infectious disease detection, and population health surveillance. The issuing bodies are primarily state departments of public health and health services agencies; the California Department of Public Health and the Texas Health and Human Services Commission / Department of State Health Services appear as recent buyers. Solicitations are structured as RFBs (request for bids) and IFBs (invitation for bids) with itemized unit pricing and firm fixed-price terms. Procurement includes set-asides and preferences for certified small businesses, minority-owned enterprises, women-owned businesses, and disabled veteran-owned businesses where state law requires them; Texas HUB subcontracting plans are encouraged but not mandatory.

Recent activity is concentrated in California and Texas. The California Department of Public Health posted RFB-IS-27200117-1 in August 2026 for public health laboratory supplies media with a response date of September 4, 2026, spanning culture media, reagents, and supporting consumables across the state's laboratory infrastructure under CBE set-asides. The Texas Health and Human Services Commission and Department of State Health Services issued IFB HHS0017310 in May 2026 for a D-10 Hemoglobin Testing System with Rack Loader and accessories to replace aging ion-exchange HPLC equipment at the South Texas Lab in Harlingen, with a response deadline of May 18, 2026; historical spending for similar goods ranged from $45,050 to $80,000 in fiscal year 2025. Both solicitations emphasize technical specifications, sterility or performance validation, and long-term supply relationships with renewal or extension options.
