Body Hair Drug Testing

What is body hair drug testing and how is it performed?

Unlike head hair, body hair drug testing can only show a history of drug use sometime between 30 days and a year in the past.

A body hair sample is typically collected by cutting or shaving hair from the arms, legs, chest, stomach, underarms, or face of a male donor. A good sample is typically the size of a large cotton ball. We do not perform body hair testing for female donors.

Who should choose body hair drug testing?

Body hair drug testing is usually performed when head hair testing cannot occur due to a lack of sufficient head hair or in cases where a history of use is suspected, but the approximate time of use isn't known or isn't important.

Unlike head hair testing, body hair drug testing does not have a hair length requirement, only a volume requirement. In general, a viable body hair sample is about the size of a large cotton ball (approximately 1 inch in diameter when bunched). If a donor is not able to provide enough of a hair sample, nail testing may be an option.

Body hair drug testing has been used successfully in legal proceedings.

How we can help.

We can provide confidential and court defensible body hair drug testing services to concerned parents, attorneys, governments, corporations and private individuals. Results can be released to multiple individuals if necessary and in some cases can even be performed anonymously.

In situations where donors are living in other states or even overseas, we can coordinate the collection of their samples where each donor resides.

If testing hasn't been set up already, it will need to be set up before any appointments or specimen collections can be made. To make the set up process quick and accurate, make sure that you have all of the necessary information first.


To set up your test you will need:

Discussing your results with the doctor

Some results may require a doctor to contact you prior to releasing the final result.

In some cases where a donor is taking a legitimate prescription drug, a false-positive may occur. Instead of releasing the result as positive, a special medical review officer (MRO) will contact you to discuss your result. You should take this opportunity to provide any prescription medication information to the doctor that may explain a positive result.


At the end of the conversation, the doctor should be able to provide you with their final determination and will then release the results for reporting.


If any positive results are explained by valid prescription use, the final result will show "Negative" for that drug instead of positive. If no prescription information is provided, or the prescription provided would not have affected the result, the final result will still show "Positive" for that drug.


You will not need to worry about contacting the doctor directly. If there are any questions about your test, the doctor will contact you first.


If you miss the doctor's call, or are unable to discuss the information with the doctor when they call, they will leave a call back number on any voice-mail or answering machine service. It is important that you call the doctor back as soon as possible. If you fail to return the doctor's call within 72 hours, the doctor may release the result without giving you the opportunity to provide any information.

Obtaining your results

Test results are normally available 5 to 10 business days after collection.

Telephone and fax results are typically available 5 days after the specimen is collected. A mailed test result is provided and typically arrive in the mail 10 to 17 days after the specimen is collected. Donors can also request to hold results at our Saint Charles office for pickup. Results are typically available for pickup 10 days after the specimen is collected. If you would like to pick up your result instead of having it mailed, please tell your collector during your appointment.


For help interpreting your results after you receive them, please call (636) 916-0050 and one of our staff would be happy to discuss your result with you.

Have Questions?

Drug testing can be embarrassing to discuss. We understand.

Normally drug testing is performed for reasons that can be embarrassing. Simply knowing that you need to take a test, or that you need to have someone test, can be stressful before you even pick up the phone to call for information. After providing your sample you have the added anxiety of waiting for the test result to come back. We understand that you will have questions and concerns. We want you to know that we will be here each step of the way to help you, even after the test results are back. If you have any questions about the testing process, help interpreting your results or would like information on where substance abuse treatment can be obtained, please give us a call.
