What is hair follicle drug test

Basis of hair follicle drug testing

The first thing to understand in the Beginners guide to hair follicle drug test is the basis of the test. Recreational drugs are consumed by inhalation, ingestion or injection. The drug enters the bloodstream and is taken to almost all parts of the body that are supplied by blood. The two most important parts of the body that receive drug are the metabolizing organ and the hair follicle. The liver is that largest drug metabolizing organ in the body. Drug metabolizing organ breaks down the drug into its metabolites. The blood stream also carries These to two most important parts of the body, which are the organ of excretion and hair follicle. Excretory organ removes the drug from the body.

Drug taken to the hair follicle is stored in the hair from the time the follicle starts to grow till when it is naturally shed, or occasionally, when shaved real close to the skin.

Site of sampling hair for hair follicle drug testing

The scalp is the common site for sampling hair for use in the test. The reason for this that scalp hair has a lifespan of 90 days. People who order the test are mostly interested in drug use of the person within the last 90 days. Another reason for this predilection is that even drug and drug metabolites in hair wane with time. It becomes harder to detect the drug after some time. Other than the scalp, hair samples can be taken from the trunk, armpits, and pubic regions.
