Urine Drug Testing
A urine drug test, also known as a urine drug screen or a UDS, is a painless test. It analyzes your urine for the presence of certain illegal drugs and prescription medications. The urine drug test may screen for multiple substances, including amphetamines, methamphetamines, benzodiazepines, barbiturates, marijuana, cocaine, opiates, PCP, methadone, nicotine, and alcohol.
Saliva Drug Testing
Saliva is the second commonly used sample for drug testing. This is used if someone (e.g. an employer) wants to know about recent drug use. Saliva drug testing can detect the presence of drugs from within a few hours up to two days after usage. It is not the best option to check long-term drug use. The donor should not ingest any food or beverages at least 10 minutes before the test.
