Glycated hemoglobin of 6.2% is slightly above the normal range; fasting blood glucose of 5.4 mmol/L is within the normal range. The normal range of fasting blood glucose is 3.9-6.1 mmol/L. When fasting blood glucose is greater than or equal to 6.1 mmol/L but less than 7.0 mmol/L and 2-hour post glycemic load blood glucose is less than 7.8 mmol/L, it suggests impaired fasting blood glucose. Glycated hemoglobin reflects the patient’s average blood glucose level in the last 8-12 weeks, and the normal value is 4-6%. In China, glycated hemoglobin is recommended as an additional diagnostic criterion for diabetes mellitus in medical institutions that use standardized testing methods and have strict quality control, and the condition for diagnosis is that the glycated hemoglobin is greater than or equal to 6.5%. If you are still concerned, you can monitor your blood glucose regularly and seek medical attention if there is any abnormality or other physical discomfort.
