A glycosylated hemoglobin of 5.8% is normal and generally does not require treatment. Glycated hemoglobin is a substance produced by combining glucose in the blood serum and hemoglobin in the red blood cells, and it can reflect the average blood glucose level in the recent 2~3 months. The normal range of glycosylated hemoglobin is generally 4% to 6%. 5.8% is within the normal range and does not require treatment, but the value is high within the normal range and needs to be rechecked on a regular basis, and fasting and postprandial blood glucose can be monitored to clarify the situation. Glycated hemoglobin is 5.8%, no need to worry too much, recommend regular review.
