There are many reasons that you may end up being required to undergo drug testing. Many employers require potential employees to agree to some type of drug testing such as a hair follicle drug test to make sure that they do not take drugs. Drugs can affect an individuals ability to perform work by affecting their judgment and causing various physical and psychological problems.
Because drugs can be very dangerous to athletes and give them an unfair advantage over their competitors, many sports organizations or coaches require athletes to undergo drug testing. Nowadays, parents are even requiring their children to undergo hair drug testing if they are worried that they may be taking illegal drugs.
A hair follicle drug test is actually one of the simplest forms of drug testing currently available. The only requirement is that a person submits a simple sample of their hair, which is very easy to do. The process involves obtaining a hair sample, which is then placed in a sealed envelope and mailed to a laboratory for examination.
Another advantage of using hair drug testing is the fact that it can be used to detect drug use for as many as 90 days. Therefore, the results of the test will still show up as positive, even if an individual has taken drugs approximately 3 months earlier. This is quite unlike other available drug tests, including urine and saliva tests, which are only able to detect drugs that have been taken a few days prior. The reason that drugs can be tested for a much longer time frame is that small amounts of chemicals from the drugs are trapped within each strand of hair.
Hair drug testing is also one of the most accurate and fastest of any type of drug test. Compared to other available types of drug tests, the accuracy of a hair follicle drug test can be ten times higher. Many employers, coaches and parents choose this type of drug testing because they desire results that are very accurate.
The confidentiality of hair testing is yet another reason why it is often the preferred drug testing method. Individuals do not have to submit embarrassing urine or saliva in order to be tested. By merely submitting a few strands of hair, very accurate results can be produced.
