The EtG test is quite sensitive and can detect even low levels of alcohol. In fact, the test can detect alcohol in the urine up to five days after consumption. In studies of participants without alcohol-use disorders, EtG has been detected in urine samples for up to 80 hours (3.3 days) after heavy alcohol exposure.
