I am a female age 46 about 146lbs, I had 2 glasses on Champgne on Saturday before 5pm and about a 6oz margarita on Sunday, had ETG test at 6pm today (Tuesday), will I pass?

It's going to be close. You're on the bubble. For chronic drinkers it can be detectable up to 80 hours. The deed and test are done now so the only thing left is the results.

What is the acceptable levels to pass? Detection is a real thing, but the levels that are detected is not so clear.

It will be close, if I had to guess, I would say no, but there is a chance
