For pricing and availability, please change the location to your nearest ARCpoint Labs.
Alcohol testing in fingernails is done by analyzing ethyl glucuronide (EtG), a direct alcohol biomarker. EtG is known as a direct biomarker because the body produces it only when ethanol is present. This test is not an under-the-influence test.
