UNSPSC 41202025: Escherichia coliserological reagents

In this classification, Escherichia coli serological reagents are devices used in test to identify specific Escherichia coli antibodies in serum. US FDA regulates Escherichia coli serological reagents under 21 CFR 866.3255 and under FDA product code GMZ.

UNSPSC 41202025 Escherichia coli serological reagents (Commodity) shows minimal direct alignment with recent state and local procurement activity. The code nominally identifies diagnostic reagents for bacterial serology, but recent opportunities posted under this classification actually encompass HIV, Hepatitis, and Syphilis testing reagents, forensic specimen analysis, drug testing services, and pool maintenance—categories unrelated to E. coli serology. Three of twelve recent opportunities posted under the code involve Abbott-manufactured HIV and Syphilis reagents procured by the Illinois Department of Public Health (emergency purchases in February and May 2026 totaling $38,079.50, and a five-year IFB in February 2026 for combination screening assays across Hepatitis B/C, HIV-1/HIV-2, and Syphilis). Two opportunities from Texas involve forensic analysis and offender drug testing services (Texas Department of Criminal Justice RFP in April 2026 for forensic analysis of biological evidence; Collin County RFP in July 2026 for offender specimen collection and drug testing, estimated value $600,000 over two years). The University of Houston RFP in March 2026 seeks blood chemistry reagents and nonautomated diagnostic testing. One opportunity from Collier County in April 2026 addresses pool maintenance and repairs—plainly unrelated to the code's stated scope.

The issuing bodies span state health departments, county corrections and public health offices, municipal health programs, and university health centers, with no standout repeat buyers beyond the Illinois Department of Public Health. Geographic activity clusters in Illinois, Texas, and Florida, with sporadic posting across other jurisdictions. The code shows a fundamental mismatch between its nominal commodity scope and current procurement reality: state and local buyers are tagging HIV, Hepatitis, Syphilis, forensic analysis, and unrelated services under a code designated for E. coli serological reagents. This classification drift signals either systematic coding error by issuing bodies or misalignment between the UNSPSC hierarchy and current diagnostic testing procurement practices. Recent opportunities within the true scope of E. coli serology do not appear in the activity block, indicating limited current demand for that specific commodity class among state and local buyers.
