The hair follicle drug test process is a simple and painless one.
A staff member of the drug testing company contracted by an employer to perform hair drug testing will cut a lock of hair of around 200mg from the crown of a person’s head.
The number of hair samples that will be taken will depend on the number of tests required.
Before taking the samples to the laboratory, the paperwork on them will have to be completed, so the employee being tested should make sure that all procedures relating to the chain of custody of the hair sample are followed to the letter.
Testing will begin once the samples reach the laboratory. The test will focus on establishing if drug metabolites, which are the parts of the drug that the body produces after consuming any substance, are present inside the shaft of the hair. The test will also try to establish the level of metabolites found in the hair. Drug use of up to three months can be detected with hair follicle drug testing.
Once the hair follicle drug test is done, a report will then be written up which will be reviewed and validated by the contractor’s toxicology expert. The results will then be sent securely within 3-7 working days upon receipt of the samples. However, it might take longer than that if the samples are being tested for complex drugs.
