UNSPSC 41181558 Rheumatoid factor immunological test system is a Commodity code representing specialized diagnostic and laboratory test equipment and related services that state and local governments procure for clinical, research, and educational applications. Recent state and local solicitations under or near this code span precision optical measurement systems, electrical equipment testing platforms, scientific software suites, laboratory instrumentation repair and maintenance, and facility environmental monitoring equipment — a diverse portfolio reflecting how taxonomy codes often capture broader technical testing and measurement capability rather than a single product line. Issuing bodies include state universities (Jackson State University, Texas State University, Texas A&M University System), municipal utilities (City of Ocala Electric Utility, Kissimmee Utility Authority, Lubbock Power & Light, City of Phoenix Water Services Department), county governments (Lee County Port Authority, Marion County Oregon, Collier County Florida), city water and wastewater departments (City of Tampa, City of Orlando), and a state health department (Texas Department of State Health Services). Repeat buyers include Jackson State University, which has posted multiple sole-source procurements for research software, and Lee County Port Authority and the City of Tampa, which have posted multiple testing and measurement service contracts.
