Why urine drug testing? Urine drug testing detects recent drug use and is the only testing method approved for federally-mandated testing.
Businesses rely on laboratory-based urine testing for its cost-effectiveness, capacity to screen for a variety of different illicit drugs and ability to withstand most legal challenges. Urine testing is suitable for all testing reasons – from pre-employment to random to post-accident – and can be performed for a wide range of illicit and prescription drugs.
What is the detection window for a lab-based, urine drug test? Urine drug testing detects recent drug use in the previous 24 to 72 hours.
What drugs are detected with a urine test? Quest Diagnostics tests for the following drugs: amphetamines, barbiturates, benzodiazepines, cocaine, marijuana, MDMA (Ecstasy) and its metabolite, methadone, opiates, oxycodone, phencyclidine (PCP) and propoxyphene, synthetic cannabinoids (“K2/Spice”) and synthetic stimulants (“Bath Salts”).
