Glycated hemoglobin 5.4% is within the normal range for both normal people and diabetic patients and is not high. 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 glycosylated hemoglobin for normal people is between 4% and 6%, so glycosylated hemoglobin 5.4% is within the normal range. 2. For patients who have been diagnosed with diabetes in the past, generally the glycated hemoglobin should be controlled below 7.0%, so the glycated hemoglobin of 5.4% is within the control target. Glycated hemoglobin mainly reflects the average blood glucose level in the last 2~3 months. 5.4% of glycated hemoglobin indicates that the patient’s average blood glucose level in the last 2~3 months is not high. When high glycosylated hemoglobin is found, timely consultation should be made.
