I drank alcohol last night . and i have a blood test today what can i do for it not to show in my results?

Depends: Entirely depends on how much you drank and how many hours between your blood test and your last drink. You need about 1-1.5 hours to burn off a standard drink. Though most routine screening blood tests do not check for an alcohol level. Unless it is for prior drinking...

Nothing: You can try hydrating with 8-10 glasses of water to dilute your urine; however, the current tests are very sensitive and accurate.
