As a general rule, patients should avoid eating or drinking anything other than water during the 12 hours prior to any blood test. Blood tests specifically prohibiting alcohol consumption in the 24 hours prior to the administration include the triglyceride test and the gamma glutamyl transferase (GGT) test.
Since trace amounts of alcohol may remain in the blood several days after consumption, patients are urged to refrain from excess alcohol intake for several days prior to any medical test or procedure, according to experts at the National Health Service.
Those that have recently consumed alcohol prior to a blood test are advised to discuss the matter with their physician to determine if the test should be postponed.
