Glycated hemoglobin of 7.1% is on the high side and is suspicious for diabetes mellitus, which should be clearly diagnosed in conjunction with clinical symptoms and other test results. The normal range of glycosylated hemoglobin is between 4.0% and 6.0%, and diabetic patients generally need to keep it below 7.0%, and also need to set up a glucose control goal according to their individual conditions. Glycated hemoglobin reflects the average blood glucose level in the last 2-3 months, and the normal range is 4.0%-6.0%. If the glycated hemoglobin is high, it is recommended to improve the examination of fasting blood glucose, postprandial blood glucose, glucose tolerance test, etc., and make a clear diagnosis in conjunction with the clinical manifestations. Glycated hemoglobin of diabetic patients should be controlled at less than 7.0%, and the glycemic control goal should be set according to the individual’s condition. Elderly patients or patients with other underlying diseases can appropriately adjust the glycemic control goal upward. The examination found that the glycated hemoglobin is 7.1%, you should promptly go to the hospital, under the guidance of the doctor’s treatment.
