Content: What happens during a vitamin E test? A health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. This usually takes less than five minutes. Will I need to do anything to prepare for the test? You will probably need to fast (not eat or drink) for 12–14 hours before the test. Are there any risks to the test? There is very little risk to having a blood test. You may have slight pain or bruising at the spot where the needle was put in, but most symptoms go away quickly.
