I drank 3/4 pint of Vodka on Friday night, last drink 11:00 PM that night. I have an ETG on Tuesay at 1 pm, any chance I might pass.

The ETG test is supposed to be sensitive to alcohol consumption from 60-80 hours. You're within that range. It is also relative to the amount that you drank. You drank, being generous, about 10 'drinks' worth of alcohol. So you binge drank for however long. I don't think I could give a 50/50 chance and I wouldn't bet on you passing. I think it is slim but you could pass.

Why do you need to take an ETG test? What happens if/when you fail? Is it worth it?
