I had 28 oz. Of beer on Sunday night at nine than went to bed at ten pm. Had the erg on Tuesday at 11:15. Will I pass the erg.

Could be close. Clearance time for two beers is noted between 25 - 39 hours by Rosano & Lin (http://www.burlingtonlabs.com/documents/ETGPublicationJATvol322008_000.pdf) using a cutoff of 100 ng while another study using same cutoff puts elimination at 28 hours. Wojcik & Hawthorne (http://alcalc.oxfordjournals.org/content/42/4/317/T2.expansion.html)

Most likely not

So there is no way of telling? Can you give me a percentile?

Not really a % but the odds are in your favor. Out of the 23 people studied only one was at the 39 hour mark. Most under 30 hours. If the test is 500 cutoff your odds are even better.

There is nothing precise in this testing process. All you can do is look at past research.

What about you nutshell? Are you speaking from experience?

Im 5'6, 150 pounds, I ate and drank plenty of water and had a couple of bananas for good measure. I don't drink really and feel like an idiot. First time I've drank in a couple weeks. Budwieser and wheat beer
