Glycated means glycated hemoglobin, the normal value reference range is 4%~6%, 5.7% is normal level. Due to different examination methods and reagents, the reference indexes of each hospital are different and need to be analyzed specifically. Glycated hemoglobin is the product of the non-enzymatic reaction between hemoglobin in red blood cells and glucose in serum. Due to its continuous, slow and irreversible characteristics, glycated hemoglobin can effectively reflect the average blood glucose level in the past 2~3 months. If the glycated hemoglobin is abnormal, it is recommended to go to a regular hospital to complete the relevant examinations and standardize the treatment under the guidance of the doctor, so as to avoid delaying the condition.
