How long does alcohol stay in your urine? Alcohol typically stays in the body for up to 24 hours after consumption, but specialized tests may be able to detect traces of alcohol even past that timeframe. For example, the EtG Urine Alcohol Test can detect urine in the body up to 80 hours after drinking.
Alcohol can last anywhere from 12-36 hours in your urine. Whether alcohol will show up will depend on how long before the test you drank, how much you drank and whether they are testing for EtG and EtS or just alcohol. If you had a glass of wine the night before they probably won't find anything.
