What Are the Best Extended Hair Drug Test Panels?
The best extended hair drug test panels detect drug use over 6, 9, or 12 months by analyzing hair samples. Hair testing captures drug metabolites embedded in hair follicles, offering a longer detection window than urine or saliva tests.
AMH Nationwide provides access to these panels through five national lab networks: Quest Diagnostics, LabCorp, Omega Labs, United States Drug Testing Labs, and ExperTox. Each panel varies in drugs tested and detection length, tailored to specific needs.
What Drugs Are Included in the Best 12 Month Hair Test Panels?
The best 12 month hair test panels typically screen for a broad range of substances, including:
These panels ensure comprehensive long-term drug use detection, which is critical for safety-sensitive positions or legal monitoring.
Panel availability and specific drug inclusions vary by lab network. Contact AMH to discuss the best extended hair panels for your testing requirements.
How Long Do Extended Hair Drug Test Panels Detect Drug Use?
Extended hair drug test panels detect drug use for 6, 9, or 12 months, depending on the panel chosen. Hair grows approximately 0.5 inches per month, and labs analyze up to 1.5 inches for 3-month detection, extending to 3-6 inches for longer detection periods.
The best extended hair panels analyze hair segments corresponding to the desired look-back period, with 12-month panels evaluating up to 6 inches or more of hair length.
| Panel Length | Approximate Hair Length Analyzed |
|---|---|
| 6-Month Panel | 3 inches |
| 9-Month Panel | 4.5 inches |
| 12-Month Panel | 6 inches or more |
Hair testing is less affected by short-term abstinence and tampering compared to urine tests, making it suitable for detecting long-term drug use.

Are Extended Hair Panels Used for DOT-Regulated Testing?
No, extended hair drug test panels are not used for DOT-regulated safety-sensitive testing. DOT requires federally certified urine testing under 49 CFR Part 40. Hair testing is accepted for non-DOT roles only.
AMH Nationwide ensures compliance by directing DOT tests through proper urine protocols while providing extended hair panels for other testing purposes.
Common Questions
A small hair sample is cut close to the scalp, typically from the crown area. The sample length depends on the detection window required, usually up to 6 inches for 12-month panels.
Hair treatments like dye or bleach can reduce drug metabolite concentrations but do not eliminate them. Labs use sophisticated methods to detect and account for such treatments.
Results typically take 5 to 10 business days after sample collection, depending on the lab network and specific panel ordered.
Yes, extended hair drug tests generally cost more due to longer detection windows and specialized analysis. Pricing varies; call AMH for specific quotes.
False positives are rare. All non-negative results undergo Medical Review Officer evaluation to confirm validity before reporting.
Some panels include prescription drugs like benzodiazepines and barbiturates. Confirm with AMH which substances are included in your selected panel.
