All About Hair Drug Testing
Hair testing the most accurate and effective method of doing a drug test. A hair test can be used to establish regular drug misusers. The need for hair drug testing has steadily increased recently and is widely used and approved by the UK courts.
A hair follicle drug test not only establishes the existance of an illegal substance, but it can also provide an a precise record of drug abuse. This aides in distinguishing between a one-off user and a persistant substance abuser.
By using a small lock of hair pulled from the scalp, a hair drugs test evaluates the number of drug metabolites embedded inside the hair shaft.
How Does Hair Follicle Drug Testing Compare with Other Drugs Tests?
In comparison to different forms of drugs testing (i.e, saliva testing), hair follicle drug testing can detect a greater period of drug use. With other drugs tests, drugs are undetectable after just a small time frame.
With hair follicle testing, the only limitation for discovering drug usage is the length of the donor's hair. Every half inch of hair in length provides a 30-day history of drug abuse.
