Urine Adulteration/Validity

Specimen validity testing (SVT) is performed on a

urine drug screen specimen to detect substitution,

adulteration, or dilution.

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.
