Glycated hemoglobin mainly reflects the average blood glucose level in the last 2 to 3 months. Glycated hemoglobin 6.2% is high and abnormal for normal people; it is within the target range and normal for diabetic patients. Due to different examination methods and reagents, the reference indexes of each hospital are different and need to be analyzed specifically. 1. The normal value of glycated hemoglobin for normal people is between 4% and 6%. If it is greater than 6%, it means that there may be elevated blood glucose level, which may be caused by diabetes, and it is recommended to consult a doctor in time for a clear diagnosis. 2. For patients who have been diagnosed with diabetes in the past, generally the glycated hemoglobin should be controlled below 7.0%, so a glycated hemoglobin of 6.2% meets the control goal and can continue the current treatment plan. When high glycosylated hemoglobin is detected, prompt medical attention should be sought.
