At one hour, your test falls into the normal, non-diabetic range if your blood glucose remains below 200 mg/dL. Two hours after your meal, blood glucose should remain below 140 mg/dL. A level of over 200 mg/dL at two hours post-prandial -- which means after a meal -- indicates diabetes.
Tests for post-prandial, or after meals, should be taken two hours after the meal. Blood Sugar Levels A normal range for blood glucose averages between 70 and 125 in most people. At two hours after eating, a blood sugar level of below 140 is considered normal. This range indicates that the body is using and metabolizing glucose properly. If the blood sugar tests in the range of 140 to 199, it can be a sign of pre-diabetes. Results over 200 means the blood sugar is in the diabetic range.
