If you are truly not a diabetic, meaning you have never been diagnosed as one or been tested and you know for sure, then your blood readings two hours after a meal should be close to
normal. less than 120. But a non-
diabetic can have slightly high readings if they've had too much food, or food that is high in sugars, carbs, etc. or a person who does not get any exercise.
You also could be borderline diabetic and don't know.
