The Schneider hair follicle drug test is an important tool in any company’s screening toolkit. It helps ensure the safety of employees and the public by keeping drug abusers out of the workplace – particularly those in safety-sensitive positions, like commercial vehicle drivers. While a urine test typically has a detection time frame of 2-5 days, a hair follicle test can detect drug use as far back as 90 days. For this reason, it is considered a more reliable indicator of drug use than urine testing.
What if I have no head or body hair?
Hair follicle drug tests are very accurate in detecting long-term drug use because of the large window of time they can detect. If the result is positive, a second test called gas chromatography–mass spectrometry (CG-MS) is performed to confirm the result. The CG-MS is a different method of testing for substances and can confirm a positive result from the ELISA test. While secondhand smoke is inhaled, there is not enough of the substance that causes the "high" (THC) in secondhand smoke to cause you to fail a drug test. This "passive exposure" will not impact your hair follicle drug test results.

Many at-home tests will charge an extra fee for the laboratory analysis, adding to the total cost of the test. A 12-drug test from one of the industry leaders in hair follicle drug testing costs about $90, including laboratory fees. Other brands can cost less (though might not test for as many substances). 10-panel drug tests can effectively test for 10 substances within their own window of detection.

This article will explore more about the test itself, the specific drugs it detects, how the test works, and what to expect when you take the test. Follow-up tests may be necessary if there are concerns about the accuracy of the results. A confirmatory test may be needed if the preliminary test has come out positive. Patients’ costs vary considerably, so it’s important to discuss questions about the cost of testing with the doctor, insurance provider, or organization ordering the testing. If your doctor has mentioned screening your blood sugar levels, you may be wondering about how to prepare for a... After confirming identifying information, the collector will cut between 100 and 120 hairs from the crown of your head.

We have a fulltime staff of experienced medical review officers always available to exam hair drug test results with quick notification back to you. Hair follicle drug tests are much more difficult to cheat than urine drug tests since a sample taken is done so directly by a trained collector. Obviously, if someone has no body or head hair, then the hair follicle test cannot be performed. A urine drug test can only detect drug use for several days, while a hair follicle drug test can pick up on drug use for a longer period of time.
How Accurate Is a Hair Follicle Drug Test?
In this article, we discuss how hair follicle drug tests work, how to use a home kit, and what the results mean. We also cover the accuracy and cost of testing, whether people without hair can still provide a sample, and how hair follicle tests compare to traditional urine-based drug tests. Whereas urine drug tests can detect recent drug use, hair follicle drug tests have a much larger window of detection. This allows persistent drug use to be detected along with more isolated instances of drug use.
With that said, some professions involving personal and public safety may require regular 10-panel drug tests. Drugs can be detected for as long as 90 days after their consumption in hair follicle drug tests. Because there is a difference in the rates at which the hair grows, it is difficult to tell the exact days on which the drug was consumed. After a hair sample is collected, it is packaged according to instructions contained in the collection kit and sent to a laboratory for testing.
The first, called ELISA, is able to deliver a negative or positive result within 24 hours. A negative result indicates that you haven’t engaged in illicit drug use over the past 90 days. Drugs.com provides accurate and independent information on more than 24,000 prescription drugs, over-the-counter medicines and natural products.
Because hair grows at a rate of 0.5 inches per month, a half inch of hair can be screened to detect approximately 30 days of drug use, including the drug type and quantity. A 1.5-inch sample of 200 strands of hair is often all that is needed to detect a 90-day window of drug use. A separate study by the University of Central Arkansas found that 300,000 drivers in the U.S. would be removed from employment if they were required to undergo a hair follicle drug screening. This precaution helps protect the individual from disciplinary action due to false positives. 10-panel drug tests are widely available online and from some specialist stores selling pharmaceutical equipment. Ordering a test through a doctor’s office or lab itself is the most direct way.
The results of the test will be reported as positive, negative, or inconclusive. You have heard all kinds of rumors about what this test can detect and how far back it can go in those detections. 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.
They involve collecting hair and then sending it to a lab for analysis. 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. Yes, the hair follicle drug test works regardless of how often one uses drugs. It is the period in which the user used drugs that determines the outcome of the hair follicle drug test. Whether a person used once or 50 times in a three month period, the hair follicle drug test will indicate that drug use.
Your hair strand test might take place in a lab or within a hospital setting. Or your workplace may perform the test using a kit that’s then mailed to a laboratory. Your hair grows at a rate of about one-half inch per month from the scalp. The standard 1.5-inch sample taken near the root provides a snapshot of drug use over the past 90 days.
This form enables patients to ask specific questions about lab tests. Your questions will be answered by a laboratory scientist as part of a voluntary service provided by one of our partners, American Society for Clinical Laboratory Science. Please allow 2-3 business days for an email response from one of the volunteers on the Consumer Information Response Team. A mouth swab drug test can detect whether you have illicit or prescription drugs in your system. Drug testing is becoming an increasingly important component of safety, security and operations across many industries.
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. Hair follicle drug testing has a longer window of detection than other types of drug tests. While drug use and misuse may not appear in the hair until 7 to 10 days after drug exposure, once it enters the hair it remains for weeks, months, or even years.
