What is a Hair Follicle Drug Test?
A hair follicle drug test is regarded as the most informative method of employee drug testing. Compared with traditional, more cost effective methods such as urine drug testing, hair drug testing offers several more benefits.
Hair drug testing has a wider window of detection for all drugs within a person’s body. A hair follicle drug test can detect drugs taken within 90 days, rather than only 30 or so. This provides employers with more information about the subject, and removes the opportunity of the subject abstaining for several days prior to being drug tested, to avoid a positive test.
A follicle drug test is far more sensitive than a urinalysis. Hair testing can reveal drugs within a subject’s system with a larger range of detection, so even drugs taken several months ago can show positive. This accuracy and sensitivity of a hair follicle drug test shows positive results more than twice as often as a urine test.
Hair drug testing flags a wide array of chemicals/drugs within a subject’s system. It provides the capability of determining drug usage patterns. A hair follicle drug test can be used to draw comparative test results, to find out when the drug was used, how long it was used for, and when use was discontinued.
