Hair follicle testing for drugs of abuse provides a long-term history on an individual’s drug use, dependent upon the length of hair. ECS offers a 3-month period of detection time. Other benefits of hair follicle testing include: inability to cheat, non-invasive, can be completed in any environment and has a longer detection period.
Hair is typically collected from the crown of the head; however, it can also be collected from the arms, legs and face in order to obtain the amount required to complete the test. Once the sample has been collected it is sent to a certified laboratory for analysis. Negative results can be known within 24 - 48 hours. Samples that require additional testing may take longer due to the confirmation and the review process by the laboratory and Medical Review Officer (MRO).
Hair testing is ideal for various drug programs; however, this method of testing is not typically used in a workplace setting due to the increased detection periods.
