UNSPSC 41202011: Citrobacter spp. serological reagents

In this classification, Citrobacter genus serological reagents are devices used in test to identify specific Citrobacter genus antibodies in serum. US FDA regulates Citrobacter genus serological reagents under 21 CFR 866.3125 and under FDA product code GTF.

UNSPSC 41202011 Citrobacter spp. serological reagents is a Commodity code that in practice captures state and local procurement of diagnostic testing reagents and related supplies — particularly rapid diagnostic test kits, immunoassay reagents, and confirmatory testing materials used in public health and clinical laboratory settings. Recent solicitations show state and local governments buying HIV test kits, syphilis and gonorrhea/chlamydia (NG/CT) reagents, drug screening supplies compatible with specific analyzer platforms, and related calibrator and control materials for CLIA-certified laboratory operations. The issuing bodies include state departments of public health (Illinois IDPH, Texas TDCJ), county health and corrections agencies (Collin County, Gwinnett County), and city public health programs (Austin). The mix reflects both clinical laboratory service procurement and specialized disease surveillance operations, with some repeat activity from Collin County and Illinois IDPH.

Recent activity spans Texas, Illinois, and Georgia. Representative solicitations include the Illinois Department of Public Health's change order (IFB, response due October 13, 2026) to increase NG/CT testing volumes from 15,000 to 25,000 annual tests and collection kits from 15,000 to 30,000 units under an existing Hologic platform reagent rental agreement, raising total contract cost to $900,000 over five years; Collin County Community Supervision and Corrections Department's RFP (response due July 23, 2026) for offender specimen collection and drug testing services including immunoassay screening and LC/MS/MS confirmation for approximately 25,031 annual tests at an estimated $600,000 over two years plus three optional one-year renewals; and the City of Austin's IFB rebid (IFB 9100 AAM1023REBID, response due September 3, 2026) for Abbott Determine HIV 1/2 rapid test kits at approximately 375 units annually for the Austin Public Health Program. Illinois IDPH also conducted emergency sole-source procurements with Abbott Laboratories in May and August 2026 totaling $38,079.50 for HIV/Syphilis reagents and related consumables for ARCHITECT i1000SR analyzers at its Carbondale Laboratory.
