What is a 19-panel hair follicle drug test?
A 19-panel hair follicle drug test is a laboratory analysis that detects the presence of 19 different drugs or their metabolites in a small hair sample. It provides a long detection window, typically up to 90 days, by analyzing hair growth. This test is used for non-DOT employment screening and other purposes requiring extended drug use history.
Which drugs are included in the 19-panel hair follicle drug test?
The 19-panel hair follicle drug test screens for a broad range of substances. These typically include amphetamines, cocaine, marijuana (THC), opiates, phencyclidine (PCP), benzodiazepines, barbiturates, methadone, oxycodone, fentanyl, tramadol, buprenorphine, ecstasy (MDMA), and others. Exact panels vary by lab but cover common drugs of abuse.
How is the hair sample collected for this test?
Hair collection involves cutting approximately 1.5 inches of hair from the crown area close to the scalp. The sample size is about the width of a pencil. Collection is performed at a designated site within the national lab networks including Quest Diagnostics, LabCorp, Omega Labs, United States Drug Testing Labs, or ExperTox. AMH Nationwide provides the lab order and directs the requester to the nearest collection site.
What is the detection window for the 19-panel hair follicle drug test?
The detection window for this test is generally up to 90 days from the date of collection. Hair grows about half an inch per month, and the standard 1.5-inch sample represents approximately three months of drug use history. This extended window makes it useful for identifying long-term drug use rather than recent consumption.

Common Questions
Hair treatments like bleaching, dyeing, or perming can sometimes reduce drug concentrations in hair. However, laboratories use sensitive methods to detect drugs despite these treatments. It is important to disclose any recent hair treatments to the Medical Review Officer during result review.
No. DOT-regulated safety-sensitive testing requires the federally certified urine protocol under 49 CFR Part 40. Hair follicle testing is used for non-DOT employment and other drug screening needs.
If the hair sample is insufficient in length or quantity, the collection site may request a repeat collection or an alternative specimen type. AMH will assist in coordinating the next steps to ensure accurate testing.
Typical turnaround time for test results is about 5 to 7 business days after sample receipt at the lab. Expedited processing may be available by request.
