Hair Follicle Testing

Many people think of drug testing as strictly a urine test. Urban legends about how to beat a urine test dot the internet. Still others may be aware of blood tests. Again, exotic methods for "cleansing" the blood capture the imaginations of online amateurs. What many don't think of is hair follicle drug testing. ReliaLab provides a hair follicle drug test that can detect drugs accurately.

How Hair Follicle Drug Testing Works

Hair drug testing is done by collecting a hair sample from the head or body. It is then analyzed for the presence of drugs, or for the byproducts of drugs. Some individuals try to beat this test by coming to the testing site with their heads shaved. Since the hair can come from anywhere on the body, this trick doesn’t work. That said, hair from different parts of the body differ in how fast they grow, so results can vary depending on where the hair was located.

Drugs We Test for Using Hair

A hair test can reveal the presence of cocaine, marijuana, codeine, morphine, 6-acetylmorphine, amphetamines, and phencyclidine (PCP). It may also find oxycodone, oxymorphone, hydrocodone, and hydromorphone.

Length of Time Hair Analysis Can Cover

A hair test using a 1 ½-inch hair may tell you whether the person has done any drugs in the last 90 days. Thinking of this another way, you can ask for a test up to 90 days after a person has ingested drugs.

Determining Current Impairment

It takes anywhere from five to ten days for drugs to reach the hair, so this test is not good for finding out if someone took drugs more recently than that. This means you can’t use hair follicle testing to discover present impairment.

Eliminating Environmental Contaminants

Many worry that smoke from marijuana can get in the hair, meaning that just being around it could result in a positive test result for someone who wasn’t smoking. We test for metabolites, the byproducts of marijuana. These are produced in the body, so only person ingesting marijuana will have the associated metabolites.

Trustworthiness of Hair Follicle Testing

This is one of the best tests for preventing cheating. There is no way to create a false result on a hair follicle test. Again, though some attempt to shave their heads, even this won’t prevent us from collecting hair elsewhere on the body.

Quick Turnaround for Results

We provide test results in 3 to 5 business days.

Chain of Custody

We are experts at maintaining the integrity of the chain of custody. That means our results can be presented in a court of law with confidence that the sample was not mishandled in any way.

The Bottom Line

Hair follicle testing gives you a much more comprehensive view of a person’s drug use than a urine test or blood test will. The drugs and their metabolites are “locked” into the hair and remain there for a long time.

Many people who are about to be tested may be surprised that they are getting a hair follicle test. Most prepare for a urine test. The element of surprise helps eliminate the ability to cheat. Also, using a hair follicle test in conjunction with other types of tests can help you build a comprehensive picture of a person’s substance abuse, so that you can make more informed choices. Having the facts on your side can be a powerful position to be in.
