I had 1 drink at 8:30 pm and left a UA test the next day at 5:30pm. Before that 1 drink I had not been drinking for 5 days. The test I took does not include th EtG. Will my test still be positive for eth

No Eddie it will not. The ethanol in your system will have long since been eliminated.

If a EtG was involved, would my test be positive

If EtG was involved, would my test then be positive?

Can you answer my second question? Thank you!

Eddie, please be patient. We are all volunteers here who graciously give of our time. Your question(s) will be answered when the person who can answer it, takes a break from family and real life signs on.

Eddie, my friend. With only one drink and two questions you managed to challenge the limits of scientific knowledge.

In direct response to your second question, and I apologize for the delay, it is unlikely that one drink would be detected by EtG testing at the time interval noted. I place primary reliance on the study of Wojcik & Hawthorne (2007) (http://alcalc.oxfordjournals.org/content/42/4/317.full#T1).

But the one drink, low alcohol intake question, highlights an interesting paradox in EtG testing that I will address shortly in the event you are interested in a more detailed response.

Thanks for your question.

You can eliminate all the worrying and stress by not drinking.
If you're not suppose to be drinking.

That's a lot of stress you put yourself through for
One drink.
I hope it was exceptionally good.
