UNSPSC 51441800: Combination diagnostic agents

This classification denotes combination drugs and preparations which produce bio or physiological data or reactions which thereafter provide practitioners means to diagnose illness, hence the term DIAGNOSTICS. Typical combination diagnostic constituents are carbon monoxide, citric acid, cosyntropin, and sodium bicarbonate.

UNSPSC 51441800 Combination diagnostic agents is a Class code that state and local governments use to procure X-ray equipment, diagnostic imaging systems, and associated maintenance and warranty services. Recent solicitations show a mix of radiologic equipment purchases—including X-ray inspection systems for security and diagnostic imaging for medical facilities—alongside extended warranty coverage and specialized maintenance plans for proprietary equipment. Issuing bodies include county health and correctional systems, county aviation departments, and county colleges, typically procuring through competitive IFBs or sole-source designations when equipment is proprietary or vendor-specific. The scope encompasses radiologic equipment procurement and installation, extended warranty contracts for existing X-ray machines, and maintenance services for specialized inspection systems, reflecting a market divided between standard equipment acquisitions and highly specialized service agreements tied to branded platforms.

Recent activity spans Florida and Arizona counties. Maricopa County (Arizona) issued IFB 362910 on October 1, 2026 for radiologic equipment and installation at three colleges with an October 22, 2026 response date. Escambia County Correction (Florida) posted sole-source solicitation SSCORALM2526005 on August 12, 2026 for an extended warranty on X-Ray equipment with an August 19, 2026 deadline. Broward County Aviation Department (Florida) issued an RFI on June 25, 2026 designating Rapiscan X-ray inspection systems (600 series, 900 series, VOTI XR3D, and Gemini) as sole-source, seeking to determine whether comparable systems or multi-source maintenance services exist, with responses due July 28, 2026. Pasco County (Florida) solicited as-needed suppliers for copper sulfate crystals and liquid copper sulfate through RFQ FP261004 posted June 3, 2026 with a June 26, 2026 response date—an outlier unrelated to diagnostic imaging or equipment, suggesting potential code-tagging misalignment in the underlying opportunity record.
