Urine Testing

Drug testing

Urine testing, one of the most common screening methods, is an accurate and reliable way to detect casual drug use that occurred within the past 72 hours. Testing is performed at all four Substance Abuse and Mental Health Services Administration (SAMHSA)-certified laboratories. Quest Diagnostics offers a variety of test panels and cutoff levels in addition to the federally mandated (SAMHSA/DOT) five-drug panel.
