Hair follicle testing
Hair testing the most effective approach of doing a drug test. Hair tests are used to prove persistent drug misusers. Although Hair drug testing can be expensive, it is a very accurate form of drug testing. The need for a hair drugs test has steadily elevated as of late and is generally used and preferred by the UK courts.
Hair tests not only ascertains the presence of a illegal drug, but it can also accommodate an accurate record of substance abuse. This aides in differentiating between a one-off user and a continuous substance user, it can also help to monitor abstinance.
Using a small sample of hair obtained from the scalp, about 50 strands or the width of a shoe lace, hair drug testing evaluates the number of drug metabolites set inside the hair shaft, and can tell you in what time period the drugs were taken.
How Does Hair Drug Tests Differ from Other Tests?
Compared to other forms of drugs testing (i.e, saliva drug testing), hair drug tests can reveal a bigger period of drug use. With these other drug tests, drugs are undetectable after just a small time frame.
With a hair drug test , the only possible problem for exposing drug usage is the length of the donor’s hair. Every half inch of head hair in length provides us with a 30-day history of drug misuse.
Overall, hair drug tests 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.
