Hair Follicle Drug Testing

Hair follicle drug testing is performed on head or body hair. The sample collected is an actual hair strand rather than the follicle being pulled from the scalp.

Hair testing is often requested when there is concern an individual or employee might attempt to cheat a urine test by submitting someone else’s urine. A hair specimen is taken directly from the individual’s head at the collection center, so cheating is not really an option.

Hair testing also provides extended detection times, and is therefore often preferred over urine, blood, and oral swab drug testing. A standard hair test will detect drugs for up to an estimated 90 days compared to urine, blood or oral swab, which only detects most substances within a few days of use. (Special note: Marijuana can be detectable in urine up to 3 to 4 weeks after use.)

We can also make special arrangements to extend the hair detection times. As long as the specimen donor has long enough hair, we can go back 6 months, 9 months, 1 year, or even longer. We have other hair test options as well. In some cases, an individual may want a segmented hair test to cover only a certain time frame, such as zero to 30 days. We can also provide at-home collections on anonymous donors for individuals who prefer to collect and test samples obtained from a hair brush or bathroom sink. For this reason, we often provide this type of testing for concerned parents and other family members.

The most commonly requested hair follicle test is the 5-panel. However, we can also check for drugs like Hydrocodone (Vicodin), Oxycodone, Percocet, Xanax, Fentanyl and Tramadol. We have knowledgeable test experts who can help ensure you are choosing the correct test. Call us today at (888) 493-2521.

 

Head and body hair collection specifications:

Hair collections through Quest Diagnostics –

The specimen donor’s hair is cut close to the rear of the crown, and as close to the scalp as possible. The collection site requires about 120 strands. If the strands are laying side by side, this will look like one-half inch (or 2 cm) of hair.

If the specimen donor has little to no head hair, or head hair is less than one-half inch long, a body hair collection can be done at some collection sites.

Possible options for body hair collections are underarm, chest, leg, or possibly facial hair. Quest cannot combine hair collected from different parts of the body.

 

Hair collections through LabCorp –

LabCorp will require the head hair to be at least 2 to 3 inches long. They will not accept body hair collections.

 

Hair collections through Omega Laboratories –

Omega Laboratories provides these guidelines:

Short hair – When the head hair is shorter than one and one-half inches, it is important to collect more hair in general, so the quantity is sufficient for testing. Consider collecting from multiple spots on the head to avoid leaving bald areas.

Long hair – For head hair collections where head hair is longer, simply wrap the remaining hair around the outside of the foil.

Curly hair – It is important to keep root ends aligned. Consider having another collector hold down the hair that has already been collected.

Thin hair – To prevent bald spots, collect hair from various spots on the head.

Braids, dreadlocks, and weaves – When the specimen donor has artificial hair connected to real hair, the artificial hair will need to be removed so the collection can be completed.

Body hair – If the specimen donor has less than one-half inch of head hair (or simply no head hair), then in some cases, a body hair collection can be done. To complete the test, one must collect a body hair sample equivalent to the size of a cotton ball. Although Omega will not accept a mixed body and head hair collection, they will allow testing on body hair collected from multiple areas.
