The normal range of preprandial blood glucose is generally 3.9~6.1mmol/L, and the normal two-hour postprandial blood glucose should be less than 7.8mmol/L. When the two-hour postprandial blood glucose is in the range of 7.8~11.1mmol/L, the glucose of the two-hour postprandial blood glucose is greater than 11.1mmol/L, and the glucose of the two-hour postprandial blood glucose is considered to be diabetes mellitus, therefore, the blood glucose of the two-hour post-breakfast blood glucose of 9.5mmol/L is considered to be abnormal glucose tolerance.
