UNSPSC 41131723: Leukocyte alkaline phosphatase test

In this classification a leukocyte alkaline phosphatase test is a device used to identify the enzyme leukocyte alkaline phosphatase in neutrophilic granulocytes (granular leukocytes stainable by neutral dyes). The cytochemical identification of alkaline phosphatase depends on the formation of blue granules in cells containing alkaline phosphatase. US FDA regulates Leukocyte alkaline phosphatase test under 21 CFR 864.7660 and under FDA product code GHD.

UNSPSC 41131723 Leukocyte alkaline phosphatase test is a Commodity code that encompasses clinical drug and substance testing supplies, reference materials, and diagnostic services state and local governments procure to support offender supervision, public safety enforcement, occupational health screening, and forensic laboratory operations. Recent activity shows issuing bodies soliciting specimen collection and testing infrastructure, laboratory supplies and reagents, confirmatory testing services, and certified reference standards for toxicology and seized-drug analysis rather than the narrow test implied by the code name alone.

The issuing-body mix spans county departments of corrections and health services, city public safety operations, county health laboratories, state forensic laboratories, university procurement operations, and specialized court programs. Collin County in Texas has posted multiple solicitations under this code within recent months—an RFP for offender specimen collection and drug testing services ($600,000 estimated annual value) and an IFB for laboratory services covering 200+ test types at approximately $70,000 annually. Recent geographic activity centers on Texas (Collin County, Texas Comptroller), Georgia (Gwinnett County), North Carolina (City of Charlotte), New Mexico (Bernalillo County), Oregon (State of Oregon, Benton County), and Florida (Pinellas County, Seminole County), with secondary activity in Wisconsin. Representative opportunities include Collin County Community Supervision and Corrections Department's RFP 2026-327 for offender specimen collection and drug testing with proposals due July 23, 2026 (estimated contract value $600,000, two-year term with three optional one-year renewals); Benton County, Oregon's RFP for urinalysis testing services supporting the Family Treatment Court Program, due July 7, 2026, requiring twice-weekly testing seven days per week; Texas Comptroller's IFB 304T-27-175A1.1 for proprietary laboratory equipment and supplies (DNA analyzers, sequencing kits, Direct ELISA kits for controlled substances) due October 20, 2026, serving Texas Department of Public Safety and Department of Parks and Wildlife statewide; and Pinellas County's Invitation to Quote for certified reference materials (131 line items of drug standards with ISO/IEC 17025:2017 accreditation) due April 23, 2026, funded through Paul Coverdell Forensic Sciences Improvement Act grants.
