How many months does a hair follicle test detect drugs?
Hair drug tests have the longest detection period, and can typically detect drug use for up to 90 days. Depending on the drugs used, a hair sample can sometimes help determine when drug use occurred and whether it’s been discontinued.
What will show up in a hair follicle test?
The most common type of hair follicle drug test is the 5-panel drug test. This test works to detect cocaine, opiates, PCP, THC, and amphetamines.
What can cause a false positive hair follicle test?
Prescription medications and certain foods, such as poppy seeds, may contain compounds that might lead to false positive results. Hair samples undergo a two-step process to ensure accurate test results. The first step involves an enzyme-linked immunosorbent assay (ELISA) test, which is a rapid screening method.
Can a hair follicle test detect infrequent use?
Regular drug users may hate this. If an individual is an infrequent or first-time drug user, a hair follicle test may not detect drug use a few days before the test because it takes time for hair to grow. Employers need to weigh that fact into their choice of a drug test method.
Can a hair follicle test be wrong?
If the hair sample is contaminated or something goes wrong during the testing, the laboratory may declare the result to be inconclusive. In these cases, a person may need to provide a new hair sample to the laboratory.
Are hair follicle tests 100\% accurate?
A positive test leads to a second step to confirm the results; that is a gas chromatography-mass spectrometry (GC-MS) test. Hair follicle testing can detect drug use within the last three months. Every individual is different, so hair follicle testing is not 100 percent accurate.
How do you remove toxins from hair follicles?
Rinse your hair with 1 cup of white vinegar and allow it to sit for at least 1 to 3 minutes, then use a clarifying shampoo. Follow with shine boost rinse or detox hair soak immediately after.
