If I drank on Tuesday and got tested just for etoh will I pass on Wednesday or Thursday?

At 24 hours you should pass any EtOH urine test. If you would like to furnish your gender, weight along with amount consumed (across what period of time) there is a formula that will provide a range of elimination.

Better yet, go to this link and provide a BAC from the calculator (be sure to check M or F in order to get proper return):
