UNSPSC 41202020: Entamoeba histolyticaserological reagents

In this classification, Entamoeba histolytica serological reagents are devices used in test to identify specific Entamoeba histolytica antibodies in serum. US FDA regulates Entamoeba histolytica serological reagents under 21 CFR 866.3220 and under FDA product code KHW.

UNSPSC 41202020 Entamoeba histolytica serological reagents is a Commodity code with little alignment between its nominal scope and current state and local procurement activity. The recent opportunities posted under this code address HIV and syphilis testing kits, hepatitis screening assays, forensic analysis of biological stains, drug-testing immunoassay screening, and clinical laboratory blood chemistry services—none of which involve Entamoeba histolytica serology. This mismatch suggests the code may be incorrectly applied in state and local procurement systems or that the tagging reflects a broader laboratory diagnostics categorization rather than the specific organism reagent named. The actual work being solicited under similar laboratory testing codes includes proprietary test kits (Abbott Determine HIV 1/2, Abbott ARCHITECT reagents), multiplex automated screening platforms for bloodborne pathogens, immunoassay and confirmatory testing infrastructure (LC/MS/MS, GC/MS), and specialized forensic serology analysis with expert witness capability. Issuing bodies include state health departments, city and county public health programs, university health centers, criminal justice agencies, and county community supervision departments. Illinois Department of Public Health appears twice in the recent record as a repeat buyer of HIV and syphilis reagents and instrumentation.

Recent opportunities span Illinois, Texas, and Florida. The Illinois Department of Public Health issued an emergency five-year IFB (26482DPHOFCDIB50489, due March 16, 2026) for HIV, hepatitis, and syphilis automated combination screening assays with estimated volumes of 13,200 HIV tests and 11,000 syphilis tests annually. Collin County, Texas Supervision and Corrections Department released an RFP (2026-327, due July 23, 2026) for offender specimen collection and drug-testing services with approximately 25,031 annual tests across immunoassay screening and confirmation modalities, estimated contract value $600,000 over two years with three optional one-year renewals. The City of Austin posted an IFB for rapid HIV test kits (IFB9100AAM1023, due July 17, 2026) supporting its Public Health Program at estimated annual volumes of 375 Abbott Determine kits and 79 control units. The Texas Department of Criminal Justice issued RFP 696-IG-26-P034 for forensic analysis of biological evidence with serology and DNA testing credentials and expert witness testimony, with proposals due May 13, 2026 and service commencement September 1, 2026. Code activity reflects established procurement patterns for infectious-disease surveillance, criminal justice compliance testing, and public health diagnostics rather than the Entamoeba histolytica organism this commodity designation names.
