Hair follicle drug testing or more accurately described as Hair Drug Testing has become a more frequently utilized testing method by employers, courts and individuals. Many employers, courts and Substance Abuse Professionals are requiring a hair drug test rather than the standard urine test. Hair drug tests oftentimes are used by employers or anyone needing a test reflecting a 90 day lookback period or detection window.
Why would someone require a hair drug test?
The primary benefit of a hair drug test includes a much longer detection period for drug use which typically is up to 90 days from when the hair sample is cut. However, when screening drug use within the last 5 days a urine drug test continues to be the most accurate test since it takes approximately 7-10 days for the drug metabolite to travel through the blood and show up in the hair.
How is a hair drug test performed?
If a donor has no hair on their body, than a hair test cannot be performed!
