It depends on the type of test and how much alcohol you consume. EtG, BAT and DOT tests include testing for alcohol, but a regular drug test often doesn’t. After all, alcohol is legal if you’re of age. However, if you are taking a test that is measuring alcohol levels, then you cannot binge drink the day before and expect to pass the test. An EtG test can detect alcohol in urine up to 8- hours after the last drink.
