We are a business to business specialty reference laboratory. We work with businesses that are trying to find better ways to help people successfully recover from substance abuse. We have tests available for any phase of life, for anyone exposed to, or suspected of ingesting, substances of abuse. 

USDTL provides substance abuse toxicology services worldwide for healthcare facilities, child protection agencies, the Department of Defense, legal services, research, businesses, and analytical and forensic laboratories.

We are a specialty laboratory inventing assays for alternate specimens, such as hair, fingernail, umbilical cord and meconium.

We push the barriers on traditional tests too, offering up to 17-panel urine assays and the ability to test for ambiguous substances like tramadol, zolpidem, bath salts, synthetic cannabinoids and more.

Along with our multiple options for adult testing, we have newborn (perinatal) drug testing that can detect substance abuse exposure in the last 20 weeks of pregnancy by testing a small piece of a newborn’s umbilical cord, potentially creating an opportunity for critical intervention when the mother might be most prone to seeking treatment. The ChildGuard hair test can detect up to 3 months of passive exposure to substances abuse, which could help support advocates seeking a safer environment. Adult drug testing ranges from lower levels of substances very recently ingested -urine- to higher levels of substance ingested 3-6 months prior – nail, hair, and dried blood spot. 

We are an ISO 170125 internationally accredited forensic laboratory. For a complete list of our certifications, please visit our website: http://www.usdtl.com/about/certifications
