The blood glucose test can be judged from the value of blood glucose measurement and the time of blood glucose measurement. The time of blood glucose measurement includes fasting blood glucose, postprandial blood glucose, etc. Fasting blood glucose refers to the blood glucose concentration measured in the state of overnight fasting for 8~10 hours, and postprandial blood glucose generally refers to the blood glucose two hours after meals. The normal range of fasting blood glucose is 3.9~6.1mmol/L, and the blood glucose is 6.1~7mmol/L when the fasting blood glucose is impaired; the normal range of two-hour postprandial blood glucose should be less than 7.8mmol/L, and the two-hour postprandial blood glucose is in the range of 7.8~11.1mmol/L when the glucose tolerance is impaired; if the two-hour postprandial blood glucose is more than 11.1mmol/L or the fasting blood glucose is more than The diagnosis of diabetes mellitus is made if the two-hour postprandial blood glucose is greater than 11.1mmol/L or fasting blood glucose is greater than 7mmol/L. If you have abnormal blood glucose values, you can go to the Endocrinology Department for further consultation.
