When hiring employees, companies want to be sure that they’re bringing on the people who are best suited for the job. Hair drug tests can be useful to companies performing pre-employment evaluations, or to employers who are conducting random screenings. Whatever the situation, this option provides clear information about possible drug usage. Here’s what you should know about this innovative testing method.

What the Test Checks

The average hair drug test is designed to test for several illicit drugs. Among them are ecstasy, amphetamines, marijuana, phencyclidine, methamphetamines, and cocaine. It can also detect the usage of opiates, including codeine, morphine, and heroin. Sometimes companies require employees to take the test before they are hired. In other cases, they may perform tests on existing employees at random to ensure a drug-free workplace.

Benefits of the Test

It’s not easy for anyone to “cheat” on a hair test. There’s no way to wash any evidence away with shampoo, for example, since drugs travel through the bloodstream. Moreover, in some cases, testing body hair may be able to provide more extensive results dating back several months. However, the test doesn’t provide any conclusive data about when drugs were initially used.

How the Test Is Performed

Tests can take place either in hospitals or in labs. The technician will first confirm your personal information, then cut approximately 120 pieces of hair from your crown. Don’t worry about losing too much hair from one place, as they can pull pieces from different areas to prevent noticeable bald spots. For those with no hair on their head, body hair may be tested.

What the Results Can Reveal

A positive test result indicates that the person’s hair test revealed the presence of some type of drug in their system. The person will generally then undergo a second, conclusive test. A negative result indicates that there was no drug presence detected, while a rare inconclusive result could suggest the sample was contaminated. In those instances, the person may need to repeat the test.
