Hair can be collected from several body locations (excluding pubic areas) and combined to obtain the required amount of hair. For body hair, collect at least 100mg of hair and more if the test is for EtG hair testing and if testing for 12 or more drugs. Although it is still fairly new technology, hair testing is very effective as long as it is administered by a properly trained technician. Our experience has allowed us to develop the expertise that has helped to make our testing processes as simple and efficient as possible. Urine drug tests can only identify drug use for approximately a week into an individual’s recent past.

Remove the cup, finish urinating, and give the sample to the lab technician. The drug test screens for delta-9-tetrahydrocannabinol (THC), the active compound in cannabis (marijuana), although it may also pick up other compounds like cannabidiol (CBD). Testing positive after using CBD will depend on whether the product contains THC, and some do. The easiest way to lookup drug information, identify pills, check interactions and set up your own personal medication records. Commonly used hair procedures (e.g., shampoos, conditioners, sprays, mousses, and gels) have no significant effect. Normal hair treatments such as bleaching, perming, and dyeing generally will not significantly lower the quantitative results.
What to know about hair follicle drug tests
Urine and blood tests can detect specific drugs in the body for up to 1-2 weeks after the last use. They look for drug metabolites, the by-products your body creates when drugs break down in your system. Hair tests also look for drug metabolites but can detect other signs of drug use on a person’s head. For instance, if you have been around someone smoking THC, the oil could transfer to your hair and produce a positive result.

Casual use can be detected up to three days; chronic use can be detected for 30 days or more. The detection window in urine depends on the type of barbiturate taken.
It is clear that additional training for collectors is needed as too many specimens are still getting rejected. A hair follicle drug test can detect drug metabolites, which are the byproducts formed when drugs are in your system. The test requires a minimum hair sample length of 1.5 inches from the head.

A Breakdown Of Drug Testing Costs For Employers
Specific pre-employment drug testing laws govern how, when, and why employers may conduct drug screenings, including hair follicle testing. Laws may vary from jurisdiction to jurisdiction, so it’s crucial to be aware of federal, state, and local rules applicable to your location and where you’re hiring. Your workplace may request a hair test to screen for illicit drug use before hire or randomly during employment. Some research also indicates that hair drug testing can be useful for monitoring drug use in at-risk individuals when used alongside self-reporting.

Hair follicle drug tests are performed on a sample of hair, usually collected from a person’s scalp. During hair follicle drug testing, scissors are used to remove a small sample of hair. Compared to other forms of drug testing, hair follicle drug testing offers advantages such as a long detection window and the ability to estimate patterns of drug use over time. Hair follicle drug testing detects evidence of drug use or misuse in a sample of hair.
The hair sample drug test is an ideal procedure both for regular workplace screening and especially for pre-employment screening. 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. If an initial screening yields non-negative results, then they will undergo additional Gas Chromatography-Mass Spectrometry (GC-MS) confirmation testing. This allows individuals that may be legitimately taking prescription medication a chance to provide authorized proof to our doctors. As long as the individual takes the medication in accordance with the prescribed dosage, then the final report will list the result as a “negative”.

The positive test result is then delivered to the test subject and/or the organization requesting the test confidentially. If you receive a negative result from the phase 1 ELISA portion of the drug test, you haven't used any drugs tested in the last 90 days. A follow-up test isn't necessary because there are no drug metabolites in your system. These tests detect the same drugs as typical panel 5, 7, 10, and 12 urine tests. How long drugs are detected by a hair follicle test depends on various factors. In contrast, urine and blood tests provide a look into an individual’s most recent drug use.
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 sample of hair can be collected at home, at a laboratory, or in a medical setting. Many parents consider using drug testing as a tool to prevent or confirm the use or misuse of drugs in children and adolescents. Professional organizations advocate for the ethical use of drug testing, often emphasizing the importance of patient education and consent before conducting a drug test.
A confirmed positive result for a drug or drug metabolite is considered evidence of use or exposure in that time period. Ethyl alcohol may be detected in urine for up to 12 hours after consumption of alcohol-containing beverages. A confirmed positive result for ethyl alcohol is suggestive of recent alcohol use.
