UNSPSC 41181558: Rheumatoid factor immunological test system

In this classification, a Rheumatoid factor immunological test system is a device that consists of the reagents used to identify by immunochemical techniques Rheumatoid factor. US FDA regulates Rheumatoid factor immunological test system under 21 CFR 866.5775 and under FDA product code DHR.

UNSPSC 41181558 Rheumatoid factor immunological test system is a Commodity code. State and local governments procure laboratory testing services and diagnostic equipment support under this code, but the recent opportunities in the source show minimal direct alignment with the nominal code scope. The tagged opportunities span laboratory testing services (phlebotomy, specimen handling, oil analysis for electrical equipment, insulating fluid diagnostics), laboratory equipment repair and maintenance (sterilization units, washers, steam generators), and procurement of specialized testing and analytical systems (spectrophotometers, lock-in amplifiers, meter test boards, servo-hydraulic fatigue systems). The issuing bodies include state health departments, county and municipal governments, transit authorities, water utilities, and public university systems across multiple states. None of the recent solicitations explicitly target rheumatoid factor testing systems or immunological assay platforms, and most opportunities address broader laboratory infrastructure, equipment servicing, or unrelated analytical instrumentation procurement. The code shows little relevant recent activity for the specific product line it nominates.

The geographic spread includes Oregon, Texas, Florida, Connecticut, California, and Texas (Lamar University and Texas A&M University System), reflecting activity across multiple regions. Representative recent opportunities include Marion County, Oregon's ITB for laboratory testing services and phlebotomy for adults in custody (due July 24, 2026), the Texas Department of State Health Services' IFB for laboratory equipment repair and maintenance at the South Texas Laboratory in Harlingen (due July 6, 2026 with historical annual values of $25,050 to $40,000), the City of Tampa's RFQ for a Heck DR4900 Spectrophotometer replacement at McKay Bay Waste to Energy (due June 12, 2026), and Lubbock Power & Light's RFP for insulating oil testing and laboratory services for electrical utility equipment across approximately 20 substations (due July 22, 2026). The source does not support meaningful characterization of repeat buyers or concentration patterns under the nominal code.
