I had two white russians about 24 hours before will it show up positive?

Probably. Why chance it. Just don't drink and you won't have to wonder if...

If the test is EtG, which tests for alcohol metabolites, it will probably test positive. If only checking for the active presence of ethanol, probably not. [I'm not much on names of drinks, but even if each contains up to 2 oz of alcohol it should be clear of active ethanol] Not clear for EtG even if each was a standard drink (1.5 oz).

How long to clear the urine of 3 ounces of Smirnoff Vodka. I drank 3 ounces on Sunday night around 6pm.
