OVERVIEW ## What makes a 6-month hair drug test court admissible? A 6-month hair drug test [court admissible](https://amhnationwide.com/hair-testing-court-admissible/) is structured to meet legal standards for evidence by ensuring strict chain of custody, use of federally certified and nationally recognized laboratories, and review by a certified Medical Review Officer (MRO). The test uses a hair sample to detect drug use over the past six months, providing a longer [detection window](https://amhnationwide.com/hair-follicle-drug-test-detection-window/) than [urine](https://amhnationwide.com/urine-drug-testing/) or saliva tests. Chain of Custody: Detailed documentation from collection to reporting Certified Labs: Testing routed through five national lab networks MRO Review: All non-negative results analyzed by a certified Medical Review Officer Authorized Release: Results only sent to legally authorized recipients These safeguards ensure the test results are defensible in court and other legal proceedings. PROCESS ## How is the 6-month hair drug test legally defensible?
