I drank about 8 beers on Friday night. And stopped drinking around 12am.. I have to get tested today (Tuesday) at around 5pm. I did the math and it has been about 85 to 88 hours since my last drink. Before this a haven't had a drink in over 2 months. What are my chances of passing an EtG test?

Estimating BAC = 0* at around 78 hours the odds of passing are about 88% or better. At the consumption noted average clearance time would be 65 hours (range 20h-90h). Based on Beck, 2007 (http://alcalc.oxfordjournals.org/content/42/4/321.full) and Helander, 2008 (http://alcalc.oxfordjournals.org/content/44/1/55.long).

This is an average derived from very small groups. There is no way to assess individual EtG elimination times accurately.

*not knowing the time span of consumption, size, gender etc I calculated BAC based on 4 hr consumption, M-165 lb.
