What is the 12-month hair drug test and how does it work?
The 12-month hair drug test how it works centers on detecting drug metabolites embedded in hair follicles, providing a long-term record of drug use. A small sample of hair, typically from the scalp, is collected and analyzed to identify substances used over the past year. This makes it distinct from urine or saliva tests that only detect recent use.
How is the hair sample collected for the 12-month hair drug test?
Hair sample collection for the 12-month hair drug test involves cutting a small, pencil-width section of hair close to the scalp. The sample is usually taken from the crown area to ensure the hair is representative of recent growth. This process is minimally invasive and requires no special preparation.
What happens after the hair sample reaches the lab?
Once collected, the hair sample is sent to one of five national lab networks: Quest Diagnostics, LabCorp, Omega Labs, United States Drug Testing Labs, or ExperTox. The lab begins with an initial screening using immunoassay techniques to detect the presence of drug metabolites.
The confirmation step is critical for accuracy, especially in legal or employment contexts. Only confirmed positives are reported as such.
What role does the Medical Review Officer play in the 12-month hair drug test process?
Every non-negative result from the lab undergoes review by a certified Medical Review Officer (MRO). The MRO evaluates the test findings in the context of the individual’s medical history and any legitimate prescriptions. This review helps prevent false positives and ensures results are medically accurate and fair.
