I drank a lot over the weekend, but my bac was zero at 6pm on Sunday. 96 hours passed from the time it was zero until I had to give a urine sample for an EtG test. Will the test be negative. Female, former heavy drinker but had been sober over three months. Worried sick. Drinking water.

At 96 hours you'll likely pass, if you didn't drink after that time.

Drinking lots of water will cause you to fail for dilution.

What do you stand to lose if you fail?
