Abstract
Assays and methods for verifying the validity of a urine sample submitted for Drugs of Abuse (DOA) testing. Embodiments include a SUD Diagnostic Panel that includes six assays: specific gravity index assay, long-duration counterfeit urine assay, short-duration counterfeit urine assay, oxidant history assay, pH assay, and creatinine assay. The SUD Diagnostic Panel detects twelve principle classes of adulteration. Detection of adulteration of one or more urine samples from a patient indicates an attempt to subvert test results and provides an objective indication in one instance and an object diagnosis in another instance of SUD.
