9-Month Hair Drug Test
9-Month Hair Drug Test for Extended Detection and Reliable Results
The 9-month hair drug test detects drug use over an extended period by analyzing a longer hair sample, providing reliable results for up to nine months. This test is ideal for employers and legal cases requiring long-term substance use history. Collection is performed at national labs including Quest Diagnostics, LabCorp, Omega Labs, United States Drug Testing Labs, and ExperTox. Call (877) 731-6362 to arrange testing.
What is a 9-Month Hair Drug Test?
A 9-month hair drug test is a specialized hair follicle drug test that detects drug use over a nine-month detection window. Unlike standard hair tests that typically analyze 1.5 inches of hair covering about 90 days, this test requires a longer hair sample, usually about 4.5 inches, to extend the detection period to nine months.
This extended detection period makes the 9-month hair follicle drug test particularly useful for employers, legal authorities, and rehabilitation programs that need to assess substance use history over a longer timeframe. The test analyzes hair samples at national labs including Quest Diagnostics, LabCorp, Omega Labs, United States Drug Testing Labs, and ExperTox.
How Does the 9-Month Hair Follicle Drug Test Work?
The 9-month hair follicle drug test works by chemically analyzing a longer segment of hair to detect drug metabolites deposited in the hair shaft over time. Hair grows approximately half an inch per month, so a 4.5 inch sample provides evidence of drug use over the past nine months.
Collection is performed at a collection site designated by AMH Nationwide, which coordinates with five national lab networks for processing. After collection, the hair sample is sent to one of these labs for analysis. Any non-negative results are reviewed by a certified Medical Review Officer to confirm findings.
Why Choose a 9 Month Hair Test Instead of a Standard 3-Month Hair Test?
The primary benefit of the 9-month hair drug test is its extended detection window, which is three times longer than the standard 3-month hair test. This allows for a more comprehensive view of a person’s drug use history, which is critical for certain employers, legal cases, and treatment programs.
Other advantages include the non-invasive collection process and the difficulty of tampering with hair samples compared to urine or saliva tests.
Who Typically Orders a 9 Month Hair Follicle Drug Test?
Employers who require long-term substance use history often order the 9 month hair drug test for pre-employment or ongoing employee screening. Legal professionals may request this test for probation or custody cases where extended drug use detection is necessary.
Rehabilitation centers and healthcare providers may also use this test to monitor long-term sobriety. Note that DOT-regulated safety-sensitive testing requires federally certified urine testing under 49 CFR Part 40; hair testing is not accepted for DOT roles.
