AMH Nationwide routes all hair follicle tests through its five national lab networks: [Quest Diagnostics](https://www.questdiagnostics.com/), [LabCorp](https://www.labcorp.com/), Omega Labs, United States Drug Testing Labs, and ExperTox. Every non-negative result is reviewed by a certified Medical Review Officer as standard procedure. WHEN TO USE ## When is the 12-panel hair follicle drug test which test the right choice? This test is appropriate when a long [detection window](https://amhnationwide.com/hair-follicle-drug-test-detection-window/) is required to assess drug use history over several months. It is commonly used by employers for [pre-employment](https://amhnationwide.com/pre-employment-hair-testing/) and random screening in non-DOT safety-sensitive roles, by courts and [probation](https://amhnationwide.com/hair-follicle-drug-test-probation/) officers for monitoring compliance, and by individuals seeking comprehensive drug use information. Employers: For comprehensive screening beyond recent use, especially non-DOT regulated positions. Courts and Probation: To monitor long-term abstinence or detect prior drug use patterns.

COMPARISON ## How does the 12-panel hair follicle drug test compare to other drug tests?
