Here are some guidelines for fasting for a blood tests: 1  It is important that you do not eat or drink anything but water. 2  You should not chew gum, smoke, or exercise before your test because all these activities can stimulate your digestive system and affect test results. 3  Avoid alcohol for at least 24 hours before your test.
