Alcohol (Biological)
Recent alcohol (last 10 days) use will be measured by the presence of ethyl glucuronide (EtG), a breakdown product of ethanol, using an ethyl glucuronide (EtG) urine test. The One Step Ethyl Glucuronide (EtG) Test Dip Card is a lateral flow chromatographic immunoassay. Each test has a control line region to serve as a procedural control and a test line region; results with only a line in the control region and without a line in the test region are classified as positive. Urine EtG ≥300 ng/mL indicates a positive result.
