My friend is on probation, however he drank two beers on Wednesday night around 8 pm and has to take a urine test on Friday. Will the alcohol show up after 30 hours?

It depends on the type of test being done.


With some urine alcohol tests, alcohol can be detected up to around 48 hours after a person has ingested alcohol. With the EtG Urine Alcohol Test, however the presence of EtG in the urine demonstrates that ethanol alcohol was ingested within the past 3 or 4 days, or roughly 80 hours after the ethanol alcohol has been metabolized by the body.
