UNSPSC 41181506: Antinuclear antibody immunological test system

In this classification, a Antinuclear antibody immunological test system is a device that consists of the reagents used to identify by immunochemical techniques Antinuclear antibody. US FDA regulates Antinuclear antibody immunological test system under 21 CFR 866.5100 and under FDA product code LSW.

UNSPSC 41181506 Antinuclear antibody immunological test system (Commodity) encompasses laboratory testing services, specimen collection, courier operations, and phlebotomy support that state and local jurisdictions procure for clinical diagnostics and occupational health screening. The code sees activity across county health departments, public health agencies, municipal corrections systems, and utility operators who conduct routine medical testing. Recent solicitations show state and local buyers treating this code narrowly: Marion County, Oregon sought laboratory testing services with phlebotomist support for adults in custody under ITB SO1814-26 (due July 24, 2026), while the Texas Department of State Health Services pursued laboratory equipment repair and maintenance for sterilization and washing equipment at its South Texas Laboratory facility under IFB HHS0017421 (due July 6, 2026). Lubbock Power & Light requested insulating oil testing and laboratory services for electrical equipment diagnostics under RFP 7131-26-ELD (due July 22, 2026), and the City of Orlando's Water Reclamation Enterprises issued a sole-source notice for technical support on the FIAnalyzer-3000 System. The code also attracts procurement for replacement lab instrumentation, exemplified by the City of Tampa's request for a Heck DR4900 Spectrophotometer under RFQ 26-P-00372 (due June 12, 2026) to replace an existing unit at its McKay Bay Waste to Energy facility.

The issuing-body mix spans state health departments, county corrections and health operations, municipal utilities, and city environmental agencies. Geographic activity concentrates in Texas (DSHS, Lubbock Power & Light), Florida (City of Tampa, City of Orlando), Oregon (Marion County), and scattered municipal and county laboratories. The code shows moderate, transactional procurement activity rather than sustained volume—most recent solicitations are single-award or term-based service contracts valued below $50,000 annually, with evaluation weighted toward technical capability (ISO/IEC 17025 accreditation, OEM certification, specialized instrumentation compatibility) and price. Vendors pursuing this code should expect repeated pre-qualification demands around laboratory certifications, equipment-specific training, data integration standards (particularly for utilities and environmental testing), and comprehensive insurance coverage.
