Hello from JustAnswer.

The usual urine test for alcohol is not for alcohol, but for a metabolite, ethyl glucuronide, or EtG. While the test for EtG is claimed to be a test that can detect alcohol use up to 80 hours after ingestion, this is actually a very unlikely upper limit. The vast majority of people with alcohol ingestion will only have a positive EtG test for 24 -48 hours after ingestion. And that is true even if the alcohol ingestion involves multiple alcoholic beverages. It is only the rare individual in whom the EtG test will still be positive 72-80 hours after ingestion.

At 3.5 days, or 84 hours, it is extremely more likely that you will be negative.

If I can provide any further information, please let me know.
