Had to take a ETG test on Friday July 10 for probation. I had 3 Smirnoff screwdrivers Saturday and one on Monday. Would that show up in the test on the 10th?

No. That is far enough along that they shouldn't be detected. The time frame is about 60-80 hours. That isn't taking into account irregularities that could fail you. For example if you drank a LOT of water, you could fail for dilution. If you're genetically special you could eliminate slower. If your system is different because of previous heavy drinking or substance abuse or medical conditions, it could eliminate slower.

Though I have to ask, if you're on probation and a condition is sobreity, why are you drinking? Are your affairs in order in case you fail a test? Is this stress worth it?
