My son had one beer Friday night about 8:30. He had to take an EtG alcohol test on Monday about 5:30 pm. Will he be able to pass this? He is a smaller man. About 135 lbs and very muscular. He works out and sweats everyday. What are his chances?

There is a limited amount of research on low level alcohol consumption/EtG elimination. Average EtG elimination time following one beer is 20.6 hours (cutoff 100 ng/ml) and have seen none longer than 30 hr. Ethylglucuronide (EtG) and Ethylsulfate (EtS) - EtG/EtS Blog

Thank you. Im not sure if I am reading this correctly. Are you saying that he has a good chance of passing?

Based on the amount consumed, 1 beer, and the time interval between drink and test, he should pass the test with time to spare.

Thank you
