It begins with a preliminary screening test, and if the results indicate drug usage, a confirmatory test is subsequently performed. This method is notable for its ability to provide a comprehensive overview of the individual’s recent substance use history and its high resistance to tampering. The hair follicle drug test uses two testing stages to avoid false positives. The first test is the ELISA test, also known as an enzyme-linked immunosorbent assay. At-home hair drug tests are available in stores and without a prescription.
What to Know About a Hair Follicle Drug Test
Many parents consider using drug testing as a tool to prevent or confirm the use or misuse of drugs in children and adolescents. The new 17-panel hair drug test is the most comprehensive drug test panel available in the United State. 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.
Types Of Drugs Hair Follicle Tests Can Detect
It can only show whether a substance has been used within the past 90 days. Cold remedies, decongestants, and hay fever medicines can show up as amphetamines and poppy seeds may show up as opiates. With over 20,000 testing centers throughout the United States, Accredited Drug Testing has testing centers in all States and in most cities and towns. There are no possession limits specified as long as the amount is consistent with the patient's needs. According to the National Institute on Drug Abuse and the CDC, in 2017, California providers wrote 39.5 opioid prescriptions for every 100 persons. This was among the lowest prescribing rates in the country and significantly lower than the average U.S. rate of 58.7 prescriptions.

Leg hair, arm hair, beard hair and underarm hair are all options if there is not 1.5 inches of head hair available. Conversely, a test positive result signals the presence of detectable drug levels, implying recent drug use within the defined detection period. Supervised testing plays a pivotal role in maintaining the accuracy and integrity of hair follicle drug test results. While most people may be familiar with urine screening drug tests, hair follicle drug tests are also used, although less widely.
Understanding the Hair Follicle Drug Test
Hair follicle testing can uncover a spectrum of drugs, including prescription medicine abuse, offering insights into the prevalence of drug misuse beyond illegal substances. Compared to blood or urine, hair provides a much longer window of detection, up to 90 days in some cases. Additionally, it’s harder to cheat a hair test, making it a reliable method for sensitive checks. Hair also tells a more detailed story, allowing for the discrimination between one-time use and habitual abuse. Because of the average growth rate of hair, a hair follicle test cannot immediately detect drug use.

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. The most common hair drug tests are designed to test for marijuana, cocaine, opiates, ecstasy, methamphetamine, MDEA, and PCP. A common misconception of a hair drug test is that the test requires a sample of the actual hair follicle. However, this is normally only required for genetic and DNA testing, according to NIH . 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. One issue with the standard urine test, however, is the duration of metabolites that are deposited in the urine.
How Does Hair Follicle Drug Testing Work?
Or your workplace may perform the test using a kit that’s then mailed to a laboratory. A 10-panel drug test screens for the presence of prescription and illicit drugs to help employers maintain a safe, productive workplace. However, if both the ELISA and the GC/MS test results are positive, that confirms the presence of specific drugs in the sample.
Testing Process
While the test is often called a hair follicle test, it is not actually the root itself that is tested. Hair drug testing uses the first inch and a half of growth from the base and roughly 120 strands, to determine any drug use within the past approximately 7 to 90 days. 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.
Now you find yourself in a dilemma, as you must prove your clean record to secure your new role. In this scenario, you must navigate the challenges of the hair drug test to ensure your employment prospects remain intact. Considering your situation, some individuals explore specialized shampoos such as Old Style Aloe Toxin Rid or Zudot Ulrta Clean to enhance their chances of passing the test.
Issues such as privacy, the potential for discrimination, and the implications of false positives or negatives are hot topics in debates. It underscores the need for strict standards and ethical practices in conducting these tests. Hair takes time to grow, and hair drug tests may not show whether a person has used drugs during the past few days. Many times, it can take between five and seven days for substances to be detectable on a hair follicle drug test.
The first step involves an enzyme-linked immunosorbent assay (ELISA) test, which is a rapid screening method.
In a laboratory-based hair follicle drug test, a professional collects a hair sample, typically from the back of the head, using specific guidelines for sample size and location. Laboratory testing is considered the most accurate and reliable method for hair drug testing. It follows strict chain-of-custody procedures to ensure sample integrity.
Our local drug testing California centers provide drug and alcohol tests that are utilized for a wide variety of court-ordered proceedings, including probation and other types of government required tests. Once the hair follicles have been analyzed by a certified laboratory they will then be reviewed and then verified by a Medical Review Officer (licensed Physician) who will than release the results. Generally a negative hair follicle drug test result is available in 2-3 days.
Once received by the laboratory, the hair sample may be washed prior to testing. Specialized methods of washing the hair sample remove some external contaminants, dirt, and grease from the surface of the hair. Once the hair sample is collected, it is sent to one of our many certified labs for professional analysis, and review from a certified Medical Review Officer (MRO). The 12-panel hair test is the most comprehensive drug test we have available.
We have a fulltime staff of experienced medical review officers always available to exam hair drug test results with quick notification back to you. The laboratory tests the drug metabolites that are embedded into the hair. If a hair drug test is required for employment, the individual who shaved their entire body will not be eligible for the jog.
Alcohol in particular has a very short life, and can lose effectiveness for detection in as little as 90 minutes. The first, called ELISA, is able to deliver a negative or positive result within 24 hours. The collection and testing of hair for this test follows a very specific set of standards to increase accuracy. During testing, the collected hair is washed and tested for environmental contamination that could change the results of the test.
