UNSPSC 41131724: Leukocyte peroxidase test

In this classification a leukocyte peroxidase test is a device used to distinguish certain myeloid cells derived from the bone marrow, i.e., neutrophils, eosinophils, and monocytes, from lymphoid cells of the lymphatic system and erythroid cells of the red blood cell series on the basis of their peroxidase activity as evidenced by staining US FDA regulates Leukocyte peroxidase test under 21 CFR 864.7675 and under FDA product code GIA.

UNSPSC 41131724 Leukocyte peroxidase test is a Commodity code that encompasses clinical laboratory testing services for drug screening, confirmation analysis, and related diagnostic work performed by state and local health, criminal justice, and occupational health agencies. Recent state and local opportunities under this code center on drug testing for probation and community supervision, pre-employment physicals with drug screening components, forensic and toxicology analysis, and specialized psychiatric medication monitoring. The issuing bodies soliciting under the code span criminal justice departments (county community supervision and corrections), county health departments, forensic laboratories, county human resources divisions, municipal college systems, and state agencies. County governments and state health or public safety departments dominate the recent activity, with Collin County (Texas), Benton County (Oregon), Seminole County (Florida), Pinellas County (Florida), Collier County (Florida), Clay County (Florida), and the State of Oregon all posting opportunities in the past four months.

The geographic spread of recent activity concentrates in Florida, Oregon, and Texas, with secondary activity in Nevada and Illinois.
