If a hair drug test is required for employment, the individual who shaved their entire body will not be eligible for the jog. Hair testing can identify various drugs, including illicit and prescription medication. Compared to other drug tests, Hair follicle drug tests have a larger detection window which can aid in identifying drug use patterns. Quitting drug use just before a hair follicle test will ensure a negative result is a myth.
Specimen Collection
All urine samples are collected and sent to the laboratory using strict chain of custody procedures that protect the identity and integrity of the specimen. The test is often used for employment screening, but it also is useful in other scenarios. Talk to your healthcare provider if you have questions about drug testing or concerns about substance use disorder. After cannabis consumption, THC and its metabolites can become incorporated into the hair shaft over time. These remnants may persist for an extended period, leading to positive test results even if cannabis use occurred weeks or months ago.
What Drugs Can Hair Follicle Tests Not Detect?
Hair samples undergo a two-step process to ensure accurate test results. During the test, the tester will remove a small hair sample close to a person’s scalp and send it to a laboratory for overnight testing. Some companies require potential employees to take a drug test as part of their application process, particularly for jobs that carry a high risk of injury. Employers may also carry out random drug testing for current employees, or they may request drug tests following serious accidents or incidents. The new 17-panel hair drug test is the most comprehensive drug test panel available in the United State. During the test, the technician or collector will cut approximately 100 to 120 hair samples from the crown of your head.
How far back does a hair follicle test detect drugs?
They can collect the hairs from different spots on your crown to avoid creating a bald spot. Drug test results always belong strictly to the donor, except in the case of a minor child or an employer or court-ordered drug test. The donor may also provide written authorization for test results to be provided to one or more third parties, if necessary. Also known as Darvocet, this is a prescription painkiller with the potential for abuse.
One urine sample can be collected and subjected to a “panel” drug test, meaning that multiple substances can be screened from one sample for increased efficiency. National Drug Screening, for example, offers a 10 panel test for up to 10 different drugs. The 5 Panel Drug Test (Blood) will identify the presence or absence of five (5) different classes of commonly abused or misused drugs and/or their metabolites. On average, most drugs are detectable in blood for approximately 24 hours after the most recent use or exposure. A confirmed positive test result may be considered evidence of real-time drug use or impairment. This guide presents an in-depth look at hair follicle drug testing, its importance for employers, and how it compares to other testing methods like urine drug tests, saliva drug tests, and blood tests.

The GC/MS also guards against false-positive results caused by foods like poppy seeds or hemp seeds. A hair strand drug test screens for illicit drug use and the misuse of prescription medication. Though commonly called a “hair follicle test,” this drug test only tests clipped strands of hair, not the follicle located under the scalp. Court ordered drug tests should contain detailed instructions specifying the type of test to be administered and the drugs that should be screened for. If sample collection needs to be witnessed in order to prevent potential tampering or substitution, those specifications will be stated in the court order. No. Unless otherwise requested, hair samples are always washed by the laboratory to remove external contaminants before testing.

The sample can be collected at the Any Lab Test Now store location of your choice. Please contact the store prior to your test appointment for additional instructions to help you prepare for your nail test. This test requires a standard blood sample that can be drawn at the Any Lab Test Now store location of your choice. You will be told to wash your hands and clean the genital area with the given cleansing cloth. Begin urinating, and then place the collection cup under the urine stream, collecting at least 1 or 2 ounces.
What’s the Window of Detection for Hair Tests?
Exposure to secondhand smoke, like weed smoke, is unlikely to lead to a positive result in hair follicle drug tests. The tests are designed to detect metabolites that are absorbed internally, not through external contact. Online hair follicle testing services allow individuals to purchase test kits online, collect their hair samples at home, and send them to a partnering laboratory for analysis.
The fact is that hair follicle tests have a detection window of approximately 3 months, so quitting shortly before the test may not be sufficient to avoid detection. The hair follicle is actually the pocket, below the scalp, from which the hair strand grows. During a hair drug test collection, the hair is cut as close to the scalp as possible, so only the strands of hair above the scalp is tested and not the actual hair follicle. True hair follicle testing requires the hair to be “plucked” rather than cut which can lead to extreme donor discomfort. For workplace drug testing, Psychemedics requires a hair sample to be collected using the proper chain-of-custody protocols to withstand a legal challenge.
The 5 Panel Drug Test Plus ETOH (Ethyl) Alcohol (Urine) will identify the presence or absence of ethyl alcohol and five (5) different classes of commonly abused or misused drugs or their metabolites. As a laboratory-based test, this panel includes a routine screen for each drug class, as well as any necessary confirmation testing. On average, most drugs are detectable in urine for approximately three days after the most recent use or exposure.

The 10-panel drug test screens for 10 different drugs, both recreational and prescription. The drug detection window varies depending on several factors, including the type of sample that is used to do the test (for example, urine vs. hair). BMI plays a crucial role in toxin retention, as individuals with higher BMI tend to have more fat tissue where drug metabolites can be stored. This can result in a longer detection window for drug tests, especially for fat-soluble substances. Conversely, a test positive result signals the presence of detectable drug levels, implying recent drug use within the defined detection period. If you’re trying to avoid a drug test and choose to shave or wax your entire body, realize that while you can circumvent giving the hair sample, you will likely be asked to take other drug tests.
