UNSPSC 51172326 Sodium edetate is a Commodity code that encompasses chemical reagents and consumables used in laboratory drug testing and specimen analysis. State and local governments procure under this code primarily through criminal justice and community supervision departments that operate offender drug testing programs. The work includes supply of immunoassay screening reagents, confirmatory testing chemicals (LC/MS/MS and GC/MS methodologies), and specimen collection consumables required to support high-volume drug screening and confirmation workflows. Collin County Community Supervision and Corrections Department and similar county-level justice agencies are the dominant issuing bodies under this code, with procurement patterns driven by contract cycles in community corrections and pretrial supervision services.

Collin County Community Supervision and Corrections Department posted RFP 2026-327 on September 25, 2026 for offender specimen collection and drug testing services with a response deadline of July 23, 2026 and an estimated contract value of $600,000 over two years with three optional one-year renewals.

Pricing is structured on a per-test basis across three service models—screening only, confirmation after screening, and screening with automatic confirmation of positives—with all costs including freight, delivery, insurance, and staffing bundled into per-test rates.
