The ETG Hair Alcohol Test determines if someone consumed alcohol before 3 months. The hair test detection period is 30-90 days depending on the length of the hair follicle. Human head hair grows at a rate of about 1/2 inch per month. It is hard to tamper with the ETG Hair follicle drug test, and it produces accurate results.
Turnaround time: 48 to 72 hours. Confirmation of positive results might take some more time.(All our recommended drug testing centers follow strict lab drug testing protocols and are FDA-approved and SAMHSA-certified.)
