The facts about hair drug testing

drug testing, hair follicle drug testing is one of the newer and more developed ways to determine whether a potential employee uses illegal substances. For those that don’t know too much about it, here are a few facts. In a hair drug test, a small sample of hair is taken from the subject, and examined to identify drugs that may have been used over a period of time. The reason this evidence is available to see through your hair is simple – when a substance is ingested, it will go to the bloodstream which flows to every part of the body, including the hair. These types of tests are much more accurate than urine tests, as drug metabolites can remain in hair follicles for years, whereas they can be flushed out of the body in a matter of days. It is also a lot more cost-effective than other forms of testing and the least invasive. Around 45 mg of hair is needed for this test and usually can discover drug use of around 90 days prior to the testing. So there’s a small insight into the facts about the hair drug tests that may be part of the pre-employment screening process.
