Some states prohibit employers from drug testing their employees on a random basis. In these states, an employer must provide evidence that supports their decision to test a particular employee. It's a biochemical test commonly used to detect antibodies and other proteins in the blood.

What happens during a hair follicle drug test?
Positive screen results are automatically sent for additional confirmatory testing by GC/MS or LC-MS/MS. Confirmatory tests will identify the specific substance(s) present in the sample and their amount(s). Screening and confirmatory tests are always conducted separately in order to prevent contamination and ensure accurate results. Hair drug testing is non-invasive, less subject to specimen tampering, and provides a wider window of detection compared to a standard urine drug test. It is also the best method for detecting patterns of chronic drug use that may be missed by a urine drug test if the timing of the test doesn’t align with recent use.

Drug test screening groups are commonly referred to as a drug testing panel. The most common panels used are a 5 panel, 10 panel and 12 panel drug tests, (panels specify how many drugs will be screened) however customized screeningings are available as well. Supervised testing plays a pivotal role in maintaining the accuracy and integrity of hair follicle drug test results. Following is the comprehensive table describing specific drugs and substances that a hair follicle drug test is typically designed to detect. Hair follicle drug tests have become increasingly popular for their reliability in detecting drug use.
Head Hair vs Body Hair
This can be collected from different spots to avoid creating a bald stop. A urine drug test is used to test for drug use over the three days preceding the test. A hair drug test is the only drug test that can detect repeated drug use up to 90 days prior to the test. The first, called ELISA, is able to deliver a negative or positive result within 24 hours. A hair drug test detects a pattern of repeated drug use over the last 90 days.
Specimen Collection
In some cases, improper collection of the hair specimen may result in the test being rejected completely. If you have very little or no hair on your head, the collector might use body hair for the test instead. The collector will place the hair in foil and then in a secure envelope to be mailed for overnight testing. Blood tests typically only detect recent cannabis use that has occurred within the last two to 12 hours. In cases of heavy use, it’s been detected up to 30 days after the last use. Accredited Drug Testing is a nationwide drug testing company with testing centers in Los Angeles, CA specializing in Drug, Alcohol, DNA testing.
How are collections performed on candidates that use artificial hairpieces or attachments to their own hair?
If only an initial test was performed, a confirmatory test may be ordered to confirm preliminary results. Hair follicle drug testing is used in workplace testing, legal and forensic testing, medical testing, and for measuring the patterns of illegal and prescription drug use. Since hair samples are obtained in full view of the collector, the process minimizes the likelihood of sample adulteration or specimen substitution. We offer hair specimen collections in many of our specimen collection sites located throughout the U.S. Our extensive network offers your employees convenient access to a Labcorp collection site.
Treatment Process
Traces of illicit drug use may be seen in a hair sample within one week of drug use. These levels are based on field studies that establish the presence of the drugs following ingestion. These levels are included in Psychemedics’ FDA submissions and are similar to the cut-off levels in the 2004 proposed SAMHSA mandatory guidelines.

Contrary to popular belief, there is no way to cleanse your hair of any drug substance. Drugs enter your bloodstream and thus, become embedded in your hair, and it stays there until that hair is removed from your body. It can only show whether a substance has been used within the past 90 days. However, the test may not be able to detect if someone uses drugs very infrequently or uses drugs shortly before the test. Hair drug testing locations are available in all areas of the United States. One of the benefits of a hair drug test is that you can't do much to cheat the test compared.
Hair Follicle Drug Testing Laws To Know
Hair drug tests may not be appropriate for determining recent 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.
Hair testing analyzes drugs within the hair shaft, rather than body fluids like urine or saliva, to determine whether drugs of abuse are present. Compared to the analysis of body fluids, hair testing is highly resistant to evasion by adulterating or substituting samples or by simply abstaining from drug use for a few days. This technology offers significantly greater detection ability than other methods of analyzing hair or body fluids. What happens when you’re asked to give a hair specimen for a drug testing program, and you’re worried about prescription drugs showing up or a false positive from exposure to drugs at home? If your work is collecting the sample for workplace drug testing, you should reach out to HR and discuss the situation confidentially.
Studies indicate that hair collected at the head’s crown grows on an average of approximately 1.3 cm (or ½ inch) per month. This growth rate may vary among people; consequently, the same 3.9cm length of hair may represent slightly different time periods. Thousands of corporations use Psychemedics’ tests to screen applicants and perform random drug tests on their employees. Schools have been using the Psychemedics test since 1997 to help their students stay drug-free. Courts routinely use Psychemedics’ test in their probation, parole, and diversionary programs. The use of hair is well established, and Psychemedics has been doing hair tests since 1987.
Psychemedics requires that the sample be submitted with Psychemedics Sample Acquisition Materials. The test subject must initial the sample to certify the sample’s authenticity at the time of collection. While saliva samples can see recent drug use as soon as 30 minutes after someone consumes a drug, hair samples are considered the most revealing as they can show long-term drug use.
Hair follicle drug testing can be ordered by a doctor or an administrator of a program that requires drug testing. Hair follicle drug tests can also be purchased through retailers without a prescription. The accuracy statistics of hair follicle testing is also different for different substances. For example, studies have shown it to be superior to urine testing in detecting cocaine and opioids, but less reliable in detecting marijuana and alcohol.
A urine drug test provides a look back period of 1-5 days while a hair drug test provides use up to 90 days from the date the specimen was collected. Imagine you’re a diligent job seeker who has just received your dream job offer from a prestigious corporation. Your acceptance of the job offer hinges on passing a comprehensive background check, which includes a 12-panel hair follicle drug test. During your college years, you used marijuana recreationally, unaware that hair follicle tests can detect drug use from up to 90 days prior. Now you find yourself in a dilemma, as you must prove your clean record to secure your new role.
Genetics and metabolic rate can significantly impact toxin elimination. Some individuals possess genetic variations that affect how efficiently their bodies metabolize and eliminate drugs. Those with slower metabolic rates may retain drug metabolites for longer periods.
