I have an EtG test tomorrow evening (tuesday) at 6:00 pm, my last drink was 9:30 pm Saturday evening. I consumed 10 beers over 7 hours, so I assume I was at .00 at 9am Sunday. That gives me about 57 hours. I'm a male, 23, 160 lbs. great metabolism and very fit. I have been running/drinking water/sauna the last two days heavily. Green Tea and B-12 as well. Any thoughts? Thanks so much. I WILL post results.

I have a very negative opinion about the usefulness of EtG testing. The results are often misleading and the test therefore unreliable for the purposes intended.

However, reading your activity and looking back over numerous other queries EtG testing may have a redeeming benefit: It does seem to motivate drinkers to exercise, drink plenty of water and take their vitamins.

As to your question, you are about 69 hours from last drink, assuming Male, your BAC was .12 or lower and BAC=0 was probably even earlier, but your estimate is as good as another.

Based on existing research you are in a fuzzy zone but from experience I have found that the vast majority of people, M&F, pass at that time interval. Can't guarantee it and you certainly pushed the boundaries and with this test that is not something you want to do.

Anxious to hear your result.

Thank you Dr. Bill, I will post when I receive them.

Hey Dr Bill, I just got my results tonight and they were negative. I can't begin to tell you the amount of pressure that is lifted off my shoulders. I will learn from this and move on, and surely won't push the boundaries of my probation again. My results say I was at 117ng. I'm not sure if my excessive exercise and consumption of water contributed to my negative results or not, but I'm sure it didn't hurt. So again, I passed an EtG after 69 hours form last drink comsuming 10/11 beers. Thanks for your time.

Thanks for posting your results but what was the 117ng?

Creatinine levels I guess. I'm not sure what the cutoff level was on the test, but I was negative across the board.

I have a very similar situation. I drank 5 vodka cranberries containing about a shot each between 12:00 and 8:00pm on Sunday. I had to test at 5:30 on Wednesday. I ran ~ 20 miles and drank plenty of water and took Vit B. I am a female and weight 125. I will let you know results!

Honestly, you should be fine. All of the exercise, sweating, and water consumed are in your favor. I know how gut-wrenching it is waiting for the results, but you should have no worries :)

I drank on a Sunday morning. A couple of shots was all. They called my color on Monday. I had to work all day so I drank as much water as I could and then drank some coffee and to my meds. If they did check for alcohol what's the liklihood of passing it?
