I may have to take an EtG test on Wednesday morning around 11am.. I am a 30 year old male 5'10 and 165 lbs.. on Saturday I drank quite heavily.. probably around 13 beers 12 oz.. I drank them within a 12 hour period.. my time from last drink until my possible test will be about 84 hours.. I've been drinking a lot of water over the past 2 days also.. what are my chances of passing.

I forgot to add that I'm pretty sure it's a 1000 ng/ml cutoff.. and if not It's 500 ng/ml
