Recently, hair testing has come to be seen as a powerful tool for the detection of drug and alcohol abuse. Hair provides a long-term history of drug and alcohol abuse by trapping biomarkers in the fibers of the growing hair strand. When collected close to the scalp, hair can provide up to a 3 month history of alcohol and drug abuse. Drug and alcohol biomarkers can appear in scalp hair 1-7 days after the last use. Hair offers a sample that is simple to collect, somewhat difficult to adulterate, and easy to ship. A 1.5 inch sample of about 200 strands of hair (about the size of a #2 pencil) closest to the scalp will give 100mg of hair, the ideal sample for screening and confirmation. For EtG, add-ons and/or tests above 10-panel, 150mg of specimen is recommended. We recommend weighing the specimen on a jeweler's scale. If scalp hair is not available, an equal amount of body hair may be collected.
