A urine drug test, also known as a urine drug screen or a UDS, is quick and painless. It tests your urine for the presence of certain illegal drugs and prescription medications. The urine drug test usually screens for alcohol, amphetamines, benzodiazepines, marijuana, cocaine, PCP, and opioids (narcotics).
Urine drug tests screen the urine for the presence of a parent drug or its metabolites. The level of drug or its metabolites is not predictive of when the drug was taken or how much the patient used. Rather, it is simply a confirmatory report indicating the presence of the parent drug or its metabolites.
