Normal fasting blood glucose is 3.9 to 6.1 mmol/L, and the normal range of blood glucose two hours after a meal should be less than 7.8 mmol/L. If the fasting blood glucose concentration is greater than or equal to 7.0mmol/L, and the two-hour postprandial blood glucose concentration is greater than or equal to 11.1mmol/L, the diagnostic criteria for diabetes are met, and the diagnosis of diabetes should be combined with clinical symptoms. If there are factors affecting blood glucose such as trauma or acute infections that cause high blood glucose levels, it is recommended that the blood glucose level be measured again after the factors have been eliminated. In the case of abnormal blood glucose values, it is recommended to go to the hospital and ask the doctor to make a judgment.
