Two-hour postprandial blood glucose generally refers to the blood glucose concentration two hours after the first bite of food, the normal range should be less than 7.8mmol/L, so two-hour postprandial blood glucose 9.5mmol/L is on the high side, and two-hour postprandial blood glucose is 7.8~11.1mmol/L, which belongs to the abnormal glucose tolerance.
