UDS vs. other: A standard urine drug screen (uds) usually does not test for ethanol (alcohol in beer/wine/etc.). Alcohol is usually tested by a blood alcohol level (bal) via blood draw. However, there is a test for urine that looks for ethyl glucuronide (etg), which is a breakdown product of ethanol, and is specifically designed to determine if you've had alcohol in the last 80 hours.
Created for people with ongoing healthcare needs but benefits everyone.
