What is Hair Follicle?
A hair follicle is a part of the skin, which grows hair by packing old cells together. Attached inside the top of the follicle are the sebaceous glands, which are tiny sebum-producing glands in almost all skin except on the palms, lips, and soles of the feet. The thicker the hair, the more the number of sebaceous glands there are.
This test, also known as a hair drug test, screens for illicit drug use and the misuse of prescription medication. Hair follicle drug tests may not be appropriate for determining recent drug use. That’s because it may take five to seven days for the drugs to be identifiable through a hair follicle test.
We can use these tests to check for a specific drug, or they can test a single hair sample for several different drugs or drug classes. Everything You Should Know About a Hair Follicle Drug Test
If someone was poisoned with Heavy Metals, Toxins, chemicals or even drugs, these substances get metabolized or absorbed into the user’s bloodstream and make it to the hair follicle in about 21-30 days after exposure. The metabolized substance is carried out from the blood into the hair follicle and traces of these substances can be detected within the hair strand length.
To collect a hair sample for a poisoning test or drug test, we require 100-125 milligram samples of hair (120 to 150 hair strands). To uphold the Chain of custody process, the hair samples cannot be provided from a brush or another unverifiable source – they must be taken directly from the donor’s head or another area of the body. For the analysis to be effective, the collector will obtain, under direct witness and observation.
For donors with very little or no head hair, the collector might use body hair, as deemed appropriate, for the test instead.
