I had eqivilant of 9 standard glasses of wine over 8 hours ending 11pm on Friday. Can I pass a UA on Monday at 8am?

CAN you? Maybe, maybe not. How lucky do you feel. That's a LOT of alcohol, and given the time before the test... there is a likelihood you might fail. Far from a certainty either way.

Based on the testing, and the time frame, and the amount you had, it's unlikely that you'll pass. But could you? Sure. Sometimes people get lucky.

Basically you drank all day Friday with 2 bottles or more of wine. Roughly 55 hours. Maybe but I wouldnt bet on it. Maybe pass but what about next time? What is the testing for? Are you constrained from alcohol? With that much wine you should seek assistance.

Agreed.

It is called an 80 hour test for a reason. If that's the test he's getting, which he doesn't specify. If it's an 80 hour test, he falls way short, which means he'll fail.

That test also test for consistent use. If it's a one time deal the OP may pass. But someone that drinks that much wine in a night, doesn't sound like a one time deal to me.

Good chance he'll fail. But miracles do happen, tests aren't always completely accurate, so he has a chance to pass. If he does, I hope he gets the help he needs so he won't have to worry about future testing.
