Hair follicle drug testing
A hair follicle drug test is the most trusted procedure of drug testing. Hair tests are used to prove consistant drug misusers. Although Hair testing can be costly, it is a very accurate form of drug testing. The demand for hair follicle drug testing has steadily increased in recent years and is mainly used and relied on by the UK courts.
A hair drug test not only verifies the residence of a illegal drug, but it can also presents a precise record of drug misuse. This helps in differentiating between a one-off user and a prolonged substance abuser, it can also help to monitor abstinance.
By using a small sample of hair obtained from the scalp, about 50 strands or the width of a small pencil, hair drug tests evaluates the number of drug metabolites embedded inside the hair shaft, and can tell you in what time period the drugs were taken.
How Does A Hair Test Compare with Other Tests?
In comparison to different varieties of testing (i.e, urine drug testing), hair drug testing can identify a greater time frame of drug use. With alternative drug tests, drugs are only detectable for a small time frame.
With hair drug tests, the only time limitation for discovering drug usage is the length of the donor’s hair. Every half inch of hair in length shows a 30-day history of drug abuse.
Overall, hair follicle drug testing is best to use when trying to establish the time frame of drug abuse and to get a test that will stand up in court. It has both advantages and disadvantages including being very accurate but expensive, it stands up in court but it only tests for one drug per payment. There are many companies that specialise in drug testing, who would be more than happy to give advice on hair testing, any drug tests or queries about drug testing or drugs in general.
