Urine drug testing (UDT):
This is the most common drug test. It requires a sample of your urine (pee). Urine drug tests are most commonly used to detect alcohol, amphetamines, benzodiazepines, opiates/opioids, cocaine and marijuana (THC).
Non-DOT Urine testing:
The most common screening method and detects recent use, typically within the previous three days. It’s also the only testing method approved for federally-mandated testing.
