I had 4 beers on Friday between 8 and 11 pm then had a EtG test on Monday at 8 am will I pass? I'm a 38 yr old female and weigh 140lbs.

No bet! Just curious why you would have 4 beers with a test less than 48 hours away? Who is the test for, as there are different criteria for different agencies or companies.

Do you know the cutoff level of the test? If it is 500Ng/Ml I would guess - that is ALL I can do here - that your chances are decent to pass after 57 hours & 4 regular drinks. With a lower cutoff level, like 100, I would not even care to venture a guess. Everyone is different and will metabolize and eliminate at different rates, so no one can give you a definitive answer how your body will react, one way or the other.

Providing some additional details such as the cutoff level (or the reason for the test, if level is unknown), as talaniman suggested, as well as drinking history may be able to assist some others in more educated guesses.
