All of our tests are analyzed by certified labs like LabCorp or Quest Diagnostics. Hair follicle tests are also always reviewed by a certified MRO (Medical Review Officer) before the results are released. If an initial screening yields non-negative results, then they will undergo additional Gas Chromatography-Mass Spectrometry (GC-MS) confirmation testing. This allows individuals that may be legitimately taking prescription medication a chance to provide authorized proof to our doctors. As long as the individual takes the medication in accordance with the prescribed dosage, then the final report will list the result as a “negative”. Although it is still fairly new technology, hair testing is very effective as long as it is administered by a properly trained technician.
FAQ 2: How far back can hair follicle testing detect drug use?
That’s because it may take five to seven days for the drugs to be identifiable through a hair test. This is possible because drugs present in the bloodstream actually become a part of hair cells as the hair grows. The sweat and sebum present on your scalp may also play a role in drug presence in existing strands of hair.

Most companies or doctors will work directly with a lab that analyzes the results of the test. Going through them to get the test done is a simple, direct approach. A healthcare provider might also order the test if you’re being prescribed amphetamines or opioids to ensure you’re complying with the prescribed amount and not giving it away or selling it to others. Also known as Darvocet, this is a prescription painkiller with the potential for abuse. The U.S. Food & Drug Administration (FDA) pulled Darvocet from the market in 2010, but it can still be purchased from drug dealers. The test will likely screen for all forms of cocaine, including crack cocaine.
How to get tested
However, there are also some kits a person can buy and send to the lab themselves. A 10-panel drug test will look for 10 of the most common drugs that a person may be abusing. This selection usually includes five common prescription medications and five illicit street drugs.
If the test is ordered, you will likely have to go to a lab to provide a urine sample. You may be asked to come back at a later date or on the same day it’s ordered. Quaaludes (methaqualone) are detectable for about two to four days in urine, and four to six months in hair.

The hair is cut as close to the scalp as possible, so only the strands of hair above the scalp are tested and not the actual hair follicle. An important factor in hair testing to consider is how the drugs got into the hair strand. Drugs can be deposited from the blood by diffusion into a hair follicle, where they then grow into the hair shaft and bind to hair proteins. Drugs may also integrate into the hair through sweat or even through environmental exposure (e.g. smoke). To reduce the likelihood that results are due to environmental contamination, Averhealth washes all hair samples prior to testing. A positive result indicates drug exposure, but it may not be possible to say how that exposure occurred.
Schneider’s Approach to Hair Follicle Testing
Additionally, according to the University of Richmond, hair follicle tests may come back positive for people who may have been exposed to certain drugs without actually using them. For example, cocaine can bind to a substance in hair called melanin, which controls the pigment of your hair. If you had entered a room where people were snorting cocaine, it’s possible some cocaine may have landed in your hair and caused you to test positive for it.
Many times specimens received at the labs are rejected for an insufficient quantity of specimen. We also see different labs quoting different quantities of hair required for hair drug testing so standardization will be very important. Several hair testing laboratories such as Quest Diagnostics, Omega Laboratories, Psychemedics and US Drug Testing Labs offer hair collection instructional brochures or short web-based video training. It is clear that additional training for collectors is needed as too many specimens are still getting rejected. New reports from Arkansas stated that 3200 drivers applying to drive for JB Hunt were told “no way” because drugs were found in their system when their hair was tested. The American Trucking Association (ATA), which lobbies for trucking companies, supports new efforts to allow hair drug testing for truckers as an alternative to urine drug testing.
How Long Are Drugs Detectable in Urine?
Many times, it can take between five and seven days for substances to be detectable on a hair follicle drug test. Hair follicle drug tests involve removing a small hair sample for laboratory testing. Results can show if a person has been using certain drugs or prescription medications in the previous 3 months.
Although hair samples undergo a two-step testing process, they are not 100 percent accurate. The cost of a hair follicle drug test can vary, depending on the kind of hair follicle test ordered (the number of drugs in a screen can differ), where you go for testing, and who ordered the test. One of the benefits of follicle drug tests is that they can show whether someone used or abused drugs as far back as three months before the test. It depends on the type of test and workplace testing program you have established. Urine and saliva tests take 1 to 5 business days, and hair follicle tests take between 4 and 10 business days.
Although the Schneider trucking company pioneered the use of hair follicle drug testing in the workplace, the test has been increasingly adopted by other companies and industries. Despite the testing evidence, there are many concerns and misconceptions about these important tests that employers must address. For instance, most employers who require testing will use a 4- or 5-panel drug test and an alcohol test.
