UNSPSC 51171636 Danthron or dantron is a Commodity code that reflects state and local procurement of drug-testing reagents and screening materials used in offender monitoring and compliance programs. In practice, the code captures the chemical reagents, immunoassay screening supplies, and confirmation testing materials (such as LC/MS/MS or GC/MS confirmation reagents) that laboratories deploy in specimen collection and drug screening workflows. State and local issuing bodies procuring under this code include county community supervision departments, corrections agencies, and public health laboratories that operate drug-testing programs for offender populations, pretrial diversion, probation compliance, and substance-abuse monitoring. The scope extends to the supply contracts that support multi-panel screening (five-panel, six-panel) and ancillary testing methodologies, as well as oral fluid and hair testing alternatives where applicable.

County corrections and community supervision departments drive recent activity under the code. Collin County Community Supervision and Corrections Department posted RFP 2026-327 on September 25, 2026, for offender specimen collection and drug testing services with an estimated contract value of $600,000 and a response due date of July 23, 2026 (note: the posted date and due date suggest this RFP was live during an earlier posting cycle). The Collin County solicitation encompasses approximately 25,031 annual tests across multiple panel configurations and ancillary testing at two collection sites in Plano and McKinney, with vendors required to maintain lab certification from SAMHSA, Texas Department of Public Safety, or the College of American Pathologists. The contract term runs two years from September 1, 2026, with three optional one-year renewal periods. 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 pricing subject to price-redetermination requests at annual anniversaries tied to medical Consumer Price Index increases not to exceed 3.0 percent annually. Recent activity is concentrated in Texas; no other state or local opportunities appear in the source.
