Hair drug tests are the most concrete way of doing a drug test. A hair drugs test is used to prove constant drug misusers. Although A hair drug test can be dear, it is a very accurate form of drug testing. The need for hair drug tests has steadily heightened recently and is commonly used and approved by the UK courts.
A hair drug test not only determines the existance of a illegal substance, but it can also accommodate an accurate historical record of substance misuse. This aides in distinguishing between a one-off user and a routine substance misuser, it can also help to monitor abstinance.
By using a small lock of hair pulled from the scalp, about 50 strands or the width of a small pencil, hair tests assesses 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 Follicle Drug Test Compare with Other Drug Tests?
Compared to more traditional types of drugs testing (i.e, saliva sample testing), hair tests can expose a greater period of drug use. With alternative drug tests, drugs are only detectable for a small time frame.
With hair follicle testing, the only possible problem for exposing drug usage is the length of the donor’s hair. Every half inch of hair in length gives us a 30-day history of drug use.
Overall, the hair test 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.
