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 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 drug test panels and cutoff levels in addition to the federally mandated SAMHSA / U.S. Department of Transportation (DOT) 5-drug panel.

Certifications
Quest Diagnostics participates in rigorous laboratory proficiency testing. 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 Six Sigma quality and service.
