Call (877) 731-6362 for scheduling and information. TURNAROUND TIME ## How long does it take to get hair follicle drug test results? Hair follicle drug test results generally take 3 to 5 business days from the date of sample collection to be reported. This timeframe allows the lab to perform the necessary analysis and for a certified Medical Review Officer to review all non-negative findings. The exact timing depends on the lab network processing the sample and the complexity of the drug panel requested. AMH Nationwide routes samples through five national lab networks: [Quest Diagnostics](https://www.questdiagnostics.com/), [LabCorp](https://www.labcorp.com/), Omega Labs, United States Drug Testing Labs, and ExperTox. TESTING PROCESS ## What happens after hair is collected for drug testing? Once the hair sample is collected at an authorized collection site, it is sent to one of AMH Nationwide’s five partner labs for analysis. The labs use advanced techniques to detect drug metabolites embedded in the hair shaft, reflecting drug use over approximately 90 days. After analysis, any non-negative results are reviewed by a certified Medical Review Officer (MRO) to confirm findings and rule out alternative explanations before releasing the final report. [DETECTION WINDOW](https://amhnationwide.com/hair-follicle-drug-test-detection-window/) ## How long do drugs stay detectable in a hair follicle test? Hair follicle drug testing detects drug use typically within the past 90 days. Drugs become incorporated into hair as it grows, providing a longer detection window than [urine](https://amhnationwide.com/urine-drug-testing/) or saliva tests. This method is useful for employers, courts, and [probation](https://amhnationwide.com/hair-follicle-drug-test-probation/) agencies requiring a longer-term view of drug use. Detection window: up to 90 days Sample length: usually 1.5 inches of hair Drugs detected: cocaine, marijuana, opiates, amphetamines, PCP, and others RESULTS RELIABILITY ## Are hair follicle drug test results accurate and reliable? Yes, hair follicle tests are among the most accurate drug testing methods available. They are less susceptible to adulteration or dilution compared to urine tests. AMH Nationwide’s use of five nationally recognized labs and MRO review ensures test integrity and compliance with [SAMHSA](https://www.samhsa.gov/workplace/drug-testing), CAP, and CLIA standards. ## Schedule Your Hair Follicle Drug Test Today To arrange hair follicle drug testing or get lab orders, call (877) 731-6362.

TEST LIMITATIONS ## Can recent drug use be detected immediately with a hair follicle test? Hair follicle drug tests do not detect very recent drug use within the past 5 to 7 days because drugs take time to incorporate into the hair shaft. For detecting recent use, urine or saliva tests are more appropriate. This test is best suited for monitoring drug use over a longer period rather than immediate consumption.
