An alcohol urine test detects the presence of ethanol (alcohol) in a urine sample, typically to document recent consumption or abstinence from alcohol. There are two main types: a direct ethanol test, which shows very recent use (within 12-24 hours), and a test for metabolites like EtG (ethyl glucuronide) and EtS (ethyl sulfate), which can be detected for longer periods, sometimes up to 80 hours after drinking, making them useful for documenting abstinence over a longer window
