Hair Drug Testing

The newest trend in drug testing is hair drug testing. US Drug Test Centers offers the hair follicle test in all areas of the United States for individuals and employers. Same-day service is available with a three- to four-business day turnaround for final hair follicle drug test results.

Why Choose a Hair Drug Test?

Drug Testing With Hair

Drug testing with hair follicles offers many benefits over the urine drug test. It's more accurate, it's harder to cheat, and it has a much longer detection window, making it a reliable method to show patterned substance use. Hair is cut as close to the scalp as possible to include the newest growth.

Let's look at these details a bit closer.

For starters, tests are always conducted by a drug test professional, who is present for the duration of the specimen collection — which isn’t always the case for urine tests. This makes it harder, if possible at all, for the individual being tested to “cheat.”

Speaking of cheating, another drawback to urine testing is that while ultimately, it’s very difficult for an individual to trick it, they can produce a diluted sample by drinking an excessive amount of water. This leads to inconclusive results and a repeat of the test.

A third benefit is that the hair follicle test can detect substance use further back than a urine test. Urine tests can look into a history of one week, while the hair follicle test has a 90-day window. Thus, hair testing is able to evaluate long-term patterns of repetitive drug use. 

Last but certainly not least, the hair follicle test is less invasive. Hair can be taken from the head, arms, or legs.

For all of these reasons combined, hair follicle drug testing provides nearly twice the number of positive drug test results, compared to urine drug testing.

Disadvantages include the test’s inability to detect single-drug use within the last three to seven days. It takes three to seven days for drug metabolites to be embedded into the hair. Hair specimen testing may not be effective for monitoring compliance on a regular basis because it cannot discriminate between recent drug use and use that occurred months earlier.

Hair follicle testing is flexible in drug panels and can also test for EtG alcohol in hair.

The Uses of Hair Follicle Testing

Many attorneys are ordering hair follicle drug tests for court-ordered drug testing, child custody drug testing, and divorce drug testing. Individuals often order hair follicle testing for personal reasons, such as when parents want to test their teenage children.

When this is the case, parents usually ask if hair collected from a brush can be used. The answer is yes, but the test will be reported as having an "anonymous" donor. It’s not possible to attribute the sample to any specific person and we cannot determine the time frame of the test, so the test result is not legally defensible.

Please note that not all of our testing centers are available for "anonymous" donor hair testing. This type of testing is only performed at our specialty laboratories.

Hair Testing for Individuals

At US Drug Test Centers, we work with individuals, court systems, child protection agencies, and attorneys for hair testing. 

You should have head hair to be able to have a hair drug test performed. If you do not have head hair, many of our facilities will take body hair from the arms or legs. Our hair testing is offered through Quest Diagnostics and LabCorp. Quest facilities will cut head hair or body hair. LabCorp facilities will only cut head hair. Our out-of-network third-party facilities will typically collect either head hair or body hair. Hair testing for EtG alcohol is tested for at our specialty laboratories.

US Drug Test Centers can provide hair follicle drug testing for employers and for individuals. Call 866-566-0261 today for immediate service.
