The test became synonymous with the Schneider company in 2007 when the company’s safety leader, Don Osterberg, read a survey showing that 10% of truck drivers admitted to using drugs. Hair follicle testing is used by employers to screen job candidates and employees for drug use. If your doctor has mentioned screening your blood sugar levels, you may be wondering about how to prepare for a... This can happen if someone in the sample gathering or analysis chain doesn't follow proper procedures. Your results won’t be affected if you wash your hair, dye your hair, or use styling products. After confirming identifying information, the collector will cut between 100 and 120 hairs from the crown of your head.
Hair Follicle vs. Urine vs. Blood Drug Tests
Prescription medications and certain foods, such as poppy seeds, may contain compounds that might lead to false positive results. Hair samples undergo a two-step process to ensure accurate test results. A person may need to undergo drug testing for employment, legal, or medical purposes. An inconclusive result may mean the hair sample was contaminated or something went wrong with testing. If you have healthy hair on the back or side of your head, a doctor can surgically remove hair strands from those areas and graft them into your scalp in a bare area.
How Accurate Is a Hair Follicle Drug Test?
Drugs enter your bloodstream and thus, become embedded in your hair, and it stays there until that hair is removed from your body. If you have alopecia, you can help hold onto your tresses by avoiding behaviors that are known to contribute to temporary and permanent hair loss, Mirmirani says. While alopecia doesn’t typically affect your physical health, the emotional and psychological distress it can cause are very real. Religious groups, including the Sikh community, have also objected to the screening practice since maintaining uncut hair is a primary expression of their faith.
What Drugs Can Hair Follicle Tests Detect?
The use of typical styling products and shampoos should not affect the test results. The first step involves an enzyme-linked immunosorbent assay (ELISA) test, which is a rapid screening method.

The collector obtains a 100-milligram sample of hair (90 to 120 strands) cut at the scalp. The collector secures the hair sample in foil and completes chain of custody documentation in preparation for shipment to the testing laboratory. Hair follicle tests provide a much broader window for detection than either urine or blood tests. These tests can glean a detailed substance usage pattern over an extended time and are most often run by employers in industries requiring a high level of alertness.
In a laboratory, a procedure called enzyme-linked immunosorbent assay (ELISA) is performed on the hair sample. The metabolites of a drug react to the test to show a positive, negative, or invalid response. A hair follicle drug test is one way to screen for recreational drug use or prescription drug abuse.
The laboratory responsible for testing will deliver the results to the individual or organization requesting the test. They’ll use confidential means, like a secure fax, a phone call, or an online interface to share test results. An inconclusive result isn’t common when testing procedures are followed. In some cases, improper collection of the hair specimen may result in the test being rejected completely. Traces of illicit drug use may be seen in a hair sample within one week of drug use.
Drug testing can screen for the use of illegal drugs, as well as the misuse of prescription medications, over-the-counter medicines, and legal substances including alcohol and tobacco. Some people think they can avoid testing positive for drugs with a hair test if they shave all the hair from their head. However, hair samples can be taken from nearly anywhere on the body, and not just on the head.
A hair follicle drug test begins with collecting a small sample of hair from close to the scalp, usually facilitated by a technician in a drug testing facility or medical office. The collected hair sample is then sent to a certified lab for testing. Drug testing can be an important component of pre-employment screening. Among the various methodologies available for drug detection, a hair follicle drug test offers unique benefits for employers who need to assess historic drug use. The test is non-invasive and provides a comprehensive overview of an individual’s substance use within a 90-day timeframe. For more information on hair sample drug tests and how they can be incorporated into your company’s workplace practices, please contact us at National Drug Screening.
Because each hair follicle has a blood vessel, drugs can travel through the bloodstream into the hair follicle. When the drug is processed (or metabolized) by a person's body, it creates byproducts called metabolites. Many people are concerned that an inch and a half of body hair will retain drug residue for a much longer period if the body hair grows much slower than the head hair. Drug panels give you (or the person requesting the drug test) the option to include alcohol in the test, expanded opiates, synthetic drugs, Benzodiazepines, and more. The type of test ordered by the judge will depend on the allegations in your case, including the type of alleged drug use and the alleged frequency of drug use.
Additionally, hair follicle tests are less likely to be affected by external factors, such as changes in temperature or humidity, that may affect other types of drug tests. The window of detection also varies based on the amount of hair tested. A hair sample taken from a different part of the body where hair grows more slowly may have a detection window of up to 12 months. The length of time the test looks at will heavily depend on the length of hair collected for the test. In some cases, it might theoretically be possible to detect drug usage 12 months back or even further. However, most standard hair follicle tests only look at your recently grown hair.
Whereas a toenail drug test can have a look back of possibly up to 12 months. Saliva tests are another option for determining drug use over a 12 month period. They are more accurate than urine tests, as they can detect drug use within the past few days. However, they are not as accurate as hair follicle tests, as they can only detect drug use within the past few days.
