UNSPSC 41181561: Systemic lupus erythematosus immunological test system

In this classification, a Systemic lupus erythematosus immunological test system is a device that consists of the reagents used to identify by immunochemical techniques Systemic lupus erythematosus. US FDA regulates Systemic lupus erythematosus immunological test system under 21 CFR 866.5820 and under FDA product code DHC.

UNSPSC 41181561 Systemic lupus erythematosus immunological test system is a Commodity code with minimal recent state and local procurement activity directly aligned to the nominal scope. The code's abstract designation—immunological testing for a specific autoimmune disease—does not map to the state and local opportunities posted under it. Recent solicitations tagged to this code span laboratory testing services for custody populations, equipment repair and maintenance, spectrophotometer replacement, electrical utility oil analysis, landscape engineering, medical device service agreements, public transit charger maintenance, construction materials testing, lab information management systems, meter test boards, water treatment plant construction, fatigue testing equipment, and lock-in amplifiers. None of these activities involve systemic lupus erythematosus testing or immunological assays specific to that condition.

The mismatch between the code's name and the actual work being solicited suggests either broad tagging practices by posting agencies or that state and local procurement offices use this UNSPSC code to capture a wider range of laboratory testing and diagnostic services than the code title implies. Jurisdictions issuing under this code include Marion County, Oregon (ITB for laboratory testing and phlebotomy services, due July 24, 2026), the Texas Department of State Health Services through HHSC (IFB for laboratory equipment repair, due July 6, 2026), the City of Tampa (RFQ for spectrophotometer replacement, due June 12, 2026), Lubbock Power & Light (RFP for oil testing laboratory services, due July 22, 2026), the County of Santa Clara (RFI for lab information management system, due April 22, 2026), and several other municipalities and special-purpose districts. Geographic activity spans Oregon, Texas, and Florida prominently, with additional solicitations from Connecticut, Arizona, and other jurisdictions. The code shows persistent low-to-moderate volume and does not indicate strong concentration among repeat buyers or a coherent market segment aligned to the code's stated immunological focus.
