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).
A urinalysis should not be confused with a urine drug screening, which examines the urine for recent use of illicit drugs. The term urinalysis is a general one meaning to examine urine, but there are different types of tests that can be performed. Urine can be examined to determine if the individual has used prescription or illicit drugs recently.
