Can You Drink Water When Fasting for Blood Tests?


It all depends with the blood test you are about to take and the doctors prescribed instructions. For instance, to test for cholesterol or blood sugar levels the doctor may request you to fast so that results of the test are not confused with the food and drinks you have taken before the test. Most physicians agree you can drink water as it doesn't have a measurable impact due to lack of fats, calories and sugar in it.
