Top best answers to the question «Fasting blood test can i drink black coffee»
- No: Fasting requires no food and no beverages (water may be allowable). Coffee contains caffeine ; other chemicals that can enter your blood stream. Drinking black coffee can skew some laboratory tests. It is not a true 12 hour fast if you drink coffee.
