Glycosylated hemoglobin 7.4% is above the normal range for both normal people and diabetics, and is abnormal. Due to different examination methods and reagents, the reference indexes of each hospital are different and need to be analyzed specifically. 1. Glycated hemoglobin mainly reflects the average blood sugar level in the last 2~3 months. In general, the normal value of glycated hemoglobin for normal people is between 4% and 6%. If it is greater than 6%, it means that the blood glucose level is elevated, which may be triggered by diabetes mellitus or caused by other reasons, such as infection, stress, etc. It is recommended to consult a doctor for a clear diagnosis in a timely manner. 2. For patients who have been diagnosed with diabetes in the past, the general glycated hemoglobin needs to be controlled at 7.0% or less, so the glycated hemoglobin of 7.4% does not reach the control target, suggesting that the blood glucose control is not good, and you should consult with a professional physician to adjust the glucose-lowering program. When high glycosylated hemoglobin is detected, timely consultation should be made.
