Intake of food or drink before a blood test depends on the type of test being done. If the test is non-fasting, then most any intake is fine. If the test is fasting, your doctor may recommend only a bit of water of possibly black coffee before the test. Your doctor or lab personnel can advise you further based on the type of test you are scheduled for. Even if tea is allowed, it is important to remember the caffeine found in many teas can be dehydrating, which can make blood draws more difficult and may alter some results.

Can you have black tea before a fasting blood test for cholesterol?

I am faced with a similar situation. I need to fast 14 hours before my blood work, and I would like some iced tea. I have only been fasting for 4 hours, so I still have 10 hours to go. I called my brother-in-law, who is a doctor in Minnesota, and he said it was fine to have the tea tonight (as long as nothing is added to it). However, I cannot drink the tea tomorrow morning before the visit. Only water.
