UNSPSC 41131619: Potentiating media for in vitro diagnostic use

In this classification, potentiating media for in vitro diagnostic use are media, such as bovine albumin, that are used to suspend red cells and to enhance cell reactions for antigen-antibody testing. US FDA regulates Potentiating media for in vitro diagnostic use under 21 CFR 864.96 and under FDA product code KSG.

UNSPSC 41131619 Potentiating media for in vitro diagnostic use is a Commodity code, but the recent state and local solicitations tagged under it show limited alignment with the code's nominal scope. The California Emergency Medical Services Board (EMSB) posted a competitive bid in August 2026 for blood transfusion equipment—specifically the Qinflow Warrior Blood Warmer system and associated consumable bags for emergency medical transport—due September 9, 2026. A second opportunity from Hillsborough County Board of County Commissioners in July 2026 sought janitorial and operational supplies for the County Fire Rescue Department, estimated at $765,679.84 for a one-year ITB contract due July 24, 2026. Neither solicitation directly addresses in vitro diagnostic media or potentiating agents as the code name describes; the EMSB opportunity relates to blood-bank and transfusion logistics, while the Hillsborough County solicitation covers general consumables for fire-station operations.

The code shows activity in California and Florida, with issuing bodies spanning state emergency-medical agencies and county procurement offices. The EMSB bid required Certified Business Enterprise (CBE) certification and compliance with technical standards, non-collusion certifications, and equal employment opportunity documentation; awards were to be made on best-value criteria. The Hillsborough County ITB required authorized-distributor status, Drug-Free Workplace Certification under Florida Statute 287.087, and compliance with a Cone of Silence during the solicitation period, with delivery to the Public Safety Operations Complex in Tampa within 10 days of purchase order receipt or five days for emergency orders. The mismatch between the UNSPSC code's diagnostic-media description and the actual work being solicited—transfusion equipment and janitorial supplies—suggests either miscoding by the issuing bodies or that this code sees minimal activity aligned with its nominal scope in current state and local procurement.
