Will a 6 pk of O'douls show up in 24 to 30 hrs?

Thanks for any help. I'm sweating a little on this. Test is Tuesday morning 8

Yes it can.

Thank YouIs there anything I can do to "flush" it out?A

No flushing will eliminate the alcohol in your urine. O'douls is low alcohol but there is some in there. The only hopeful news is that the EtG is frequently wrong.

You have done the deed and hopefully you will fall under the acceptable level to pass. Trying to cheat or fool the test may be a lot worse than taking your chances to be honest because dilution (flushing) can be easily detected and is a FAIL when it is.

The important thing is to learn from this mistake, and realize a few drinks is not worth the stress of failing a drug test. Why are you taking a test in the first place, as different agencies have different acceptable levels to pass.

What is the price of failure?

I'm on probation for 1 year. They will drug/alcohol test sometimes. I did not realize that N/A beer had alcohol until I had 6 of them, someone told me at a party (Memorial Weekend with family). Obviously I stopped as soon as I was advised of this.My test is Tuesday at 8.Yes I feel stupid, I've never been on probation before and I assumed if label said N/a it was... you Non Alcohol.I will pay the price if I do get tested. I realize that.

A vague rule of thumb for NA beer is 2 days.

You asked this last night, Sunday, yet the test isn't until Tuesday morning. If you drank it Sunday around 6 pm or so, that will be 38 hours, not 24 to 30. But as everyone has said, any typical parameters are not etched in stone.
Any flush will be detected, and if you use tons of water, that waters down your urine, and they detect that too.
