Urine testing panels and cutoffs
Urine drug testing, one of the most common screening methods, is an accurate and reliable way to detect drug use.
Drug testing is performed at all three of our Substance Abuse and Mental Health Services Administration (SAMHSA)-certified laboratories. Quest Diagnostics offers a variety of drug test panels and cutoff levels in addition to the federally-mandated SAMHSA / US Department of Transportation (DOT) 5-drug panel.
Quest Diagnostics participates in rigorous lab proficiency testing. All of our drug testing laboratories hold and maintain Clinical Laboratory Improvement Amendments of 1988 (CLIA-88), SAMHSA, and College of American Pathologists (CAP) certification as well as any applicable state licensure. We are committed to the highest standards of quality.
