Hair follicle drug testing is the most precise method of testing for drugs. Hair drug testing is used to prove repeated drug abusers. The need for hair testing has steadily heightened recently and is widely used and approved by the UK courts.
A hair drug test not only verifies the presence of an illegal substance, but it can also accommodate an an accurate record of substance abuse. This assists in distinguishing between a one-off user and a sustained substance abuser.
Using a small collection of hair collected from the scalp, a hair follicle drug test assesses the number of drug metabolites embedded inside the hair shaft.
How Does Hair Tests Differentiate from Other Tests?
Compared to other types of drugs testing (i.e, saliva sample testing), hair drug testing can uncover a longer time frame of drug use. With alternative drugs tests, drugs are only detectable for a small time frame.
With a hair follicle drug test, the only possible problem for discovering drug usage is the length of the donor’s hair. Every half inch of hair in length provides us with a 30-day history of drug abuse.
