Urine Screening

Urine drug screening is a clinical tool that can enhance workplace safety,

monitor patients’ medication compliance, and detect drug (illicit and prescription)

abuse as well as prescription medication diversion. 

  1. Identifies possible use or non-use of drugs or drug classes, and includes point-of-care (POC) and laboratory immunoassay (IA) methods.

  2. Results are reported qualitatively (Negative or Positive), and does not identify drugs/metabolites.

  3. Requires definitive mass spectrometry to identify drug/metabolite present.
