Hair testing has come to be seen as a powerful tool for the detection of alcohol abuse. Hair provides a long-term history of 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 abuse. Alcohol biomarkers can appear in scalp hair 1-7 days after the last use. Hair offers a sample that is simple to collect and difficult to adulterate.
We will collect about 200 strands of hair (about the size of a #2 pencil) closest to the scalp. The length needed to go back the 90 days is 1.5 inch for screening and confirmation.
If scalp hair is not available, we can then collect about a cotton ball size of body hair.
