Several large trucking companies are now performing hair testing in addition to the required 5 panel urine lab-based testing. Some of these companies include JB Hunt, C. R. England, Schneider Trucking, Swift Transportation, Shell Oil, and others. These companies cite safety and the large investment required as their motivation for conducting hair drug testing in addition to required DOT urine drug testing. Hair drug testing has also become popular for workplace drug testing for potential hires.

This drug test analyzes hair follicles to detect drug use over a longer period, usually up to 90 days. This test identifies a range of substances, including marijuana, cocaine, opioids, and more. Results typically take about 3 to 5 days, providing insights into an individual's drug history for various purposes such as employment or legal requirements. The DOT urine drug test is available upon request and follows the regulations set by the Department of Transportation (DOT). This urine test checks for drug use, including substances like marijuana, cocaine, opioids, and amphetamines. It's a convenient testing option, ensuring compliance with DOT guidelines, and offers timely results for workplace or regulatory purposes.

In some cases, the collection of a hair sample will be performed by a trained professional to prevent tampering, contamination, or substitution of the sample. Before taking a hair follicle drug test, patients should ask the organization requiring drug testing about requirements for hair sample collection. At National Drug Screening, we make it easy to order a hair test online or by phone.

When considering the use of an at-home hair follicle drug test, it’s important to consider whether the company offers confirmatory testing for positive screening results. 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.
Hair drug testing
Drug tests performed in a hospital or laboratory may cost between $100 and $125. One 2017 study did find inconsistency between self-reporting of cannabis use and the results of hair drug tests. Your workplace may request a hair test to screen for illicit drug use before hire or randomly during employment.
Positive
Using strategic partners, Labcorp offers initial screening tests performed by immunoassay with confirmation of presumptive positive screens by mass spectrometry. Results for specimens that screen negative for all drugs are generally available within 48 to 72 hours after specimens are received at the laboratory. Results for confirmation testing of presumptive positive screens are usually available within an additional 72 hours. 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 drugs of abuse testing offers up to a 90-day window for detection of drug use and a convenient collection process that can be performed almost anywhere.
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. Most laboratories will only test about 1.5 inches of head hair without a special request and increased cost.
Hair can be collected from several areas on the body, and drugs can be detected several days after use. Drug use can continue show up in hair up to a year after use, depending on the length of the hair strand[1]. For this reason and others – including that hair is difficult to adulterate or substitute[2],[3] – hair testing in substance use monitoring is becoming more common. Accredited Drug Testing Inc. is pleased to provide hair follicle drug testing, alcohol testing, occupational health and DNA testing services in , . In the near future, hair drug testing may be allowed in the DOT mandated drug and alcohol testing program. 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.
Because hair growth rates vary from person to person, this test can’t accurately determine when in the 90 days drugs were used. While a urine drug screen can detect if you’ve used drugs in the last few days, a hair drug test can detect drug use in the past 90 days. One issue with the standard urine test, however, is the duration of metabolites that are deposited in the urine. Alcohol in particular has a very short life, and can lose effectiveness for detection in as little as 90 minutes. Other industries that have embraced hair testing include, but are not limited to, the oil and gas industry, the gaming industry, and the auto manufacturing industries.
However, it will not reveal the use of any drugs used within the last week. Urine drug tests can only identify drug use for approximately a week into an individual’s recent past. For that reason, hair drug or hair alcohol EtG tests are better suited to detect binge or chronic drug usage over a more extended period of time.
Hair follicle drug testing is a type of drug test that analyzes a small sample of hair to detect the presence of drugs in the body. This type of test can detect drug use over a longer period of time than other types of drug tests, making it a popular choice for employers and other organizations. A standard hair drug test detects drug metabloites in the hair for an approximate 90 day lookback period.
Our drug testing centers are available in all areas of the United States. Often called hair follicle drug test, the hair follicle is not actually tested. The metabolites of the drugs go into the hair follicle and then into the hair strands. The hair strands are cut as close to the scalp as possible for drug testing. Beyond the ethical implications of drug use in a professional setting, there are, of course, legal considerations.
