13 Panel Hair Follicle Drug Test for Reliable Long-Term Drug Detection
The 13 panel hair follicle drug test analyzes hair samples to detect drug use within approximately 90 days. This test is used by employers, courts, and individuals for comprehensive substance screening. Samples are processed through five national lab networks with results reviewed by certified Medical Review Officers. Call (877) 731-6362 to schedule a test.
What is a 13 panel hair follicle drug test?
A 13 panel hair follicle drug test screens for 13 different drugs or drug classes by analyzing a small sample of hair. It detects drug metabolites embedded in the hair shaft, reflecting substance use over the prior 90 days. This test is suitable for employment screening, legal requirements, and individual monitoring.
AMH Nationwide coordinates the lab order and directs clients to one of over 20,000 collection sites nationwide. Samples are analyzed by one of five national lab networks: Quest Diagnostics, LabCorp, Omega Labs, United States Drug Testing Labs, or ExperTox.
Which drugs are included in the 13 panel hair follicle test?
The 13 panel hair follicle test typically includes detection of these substances:
Specific panels may vary slightly depending on the lab and requester requirements. Contact (877) 731-6362 to confirm substances tested.
How long does the 13 panel hair follicle drug test detect drug use?
The 13 panel hair follicle test detects drug metabolites deposited in hair as it grows, providing a detection window of up to 90 days. Hair grows approximately 0.5 inches per month, and a standard 1.5-inch sample represents about three months of history.
This test cannot detect very recent drug use within the past 5-7 days because hair near the scalp has not yet grown out. It is designed for identifying longer-term patterns of drug use rather than immediate or one-time use.
How reliable is the 13 panel hair follicle test?
The 13 panel hair follicle drug test is highly reliable when properly collected and processed. Hair samples are collected under chain of custody protocols and analyzed by accredited labs aligned with SAMHSA, CAP, and CLIA standards.
All non-negative results undergo review by a certified Medical Review Officer (MRO) to verify findings and consider legitimate medical explanations. The test is not affected by short-term detox or passive exposure to drugs at typical environmental levels.

Who typically orders a 13 panel hair follicle drug test?
Employers use this test for pre-employment screening and ongoing compliance, especially in safety-sensitive industries. Courts and probation agencies require it for monitoring substance abstinence over time.
Individuals may also request this test for personal monitoring or legal purposes. AMH Nationwide facilitates the lab order and collection process but does not provide direct online ordering.
What is the hair sample collection process for this test?
A trained collector cuts approximately 1.5 inches of hair closest to the scalp from the crown area, typically requiring about 100-150 strands. The sample is sealed and sent to one of the five national labs for analysis.
No special preparation is needed. The collection is non-invasive and can be completed quickly at any of the nationwide collection sites. Call (877) 731-6362 to find a nearby location.
How much does the 13 panel hair follicle drug test cost and how are results delivered?
Pricing varies by panel configuration and detection window requirements. Contact (877) 731-6362 for a personalized quote.
Results are typically available within 3 to 5 business days after sample receipt. All results are reviewed by a Medical Review Officer before release to ensure accuracy and proper interpretation.
Common Questions
Yes, the test can detect one-time drug use if the use occurred within the approximately 90-day detection window. However, very recent use within 5 to 7 days may not be detected because the hair containing metabolites has not yet grown out.
Passive exposure to drugs through environmental contact typically does not result in positive hair follicle test results. The test detects metabolites inside the hair shaft, which requires actual ingestion or consumption.
No, DOT-regulated safety-sensitive testing requires federally certified urine testing under 49 CFR Part 40. Hair follicle testing is used for non-DOT roles and other screening purposes.
A small sample of hair, usually 1.5 inches in length and about 100-150 strands, is cut close to the scalp from the crown area. This sample represents approximately 90 days of hair growth.
Results are generally available within 3 to 5 business days after the lab receives the hair sample. All positive or non-negative findings are reviewed by a certified Medical Review Officer before release.
