I was wondering if a person can pass an EtG test after 56 hours after drinking about 3-4 glasses of red 14% wine and 1 shot of vodka? This person is not a regular drinker as they haven't drank for about 5 months and does water and coffee help flush it out?

Diluted urine is also a reason to fail a test.

I think the alcohol will be out of your system.
