Glycated hemoglobin 6.1%, the estimated average blood glucose value is about 7.0mmol/L. This value is only an estimate, it is recommended to improve the examination of fasting blood glucose and 2 hours postprandial blood glucose specific value, to better assess the condition. Glycated hemoglobin can reflect the average blood glucose concentration in the past 2~3 months, which can evaluate the long-term blood glucose control, and is also an important basis for guiding the clinical adjustment of the treatment plan. The normal range is generally 4%~6%. Glycated hemoglobin cannot replace the testing of fasting blood glucose, 2-hour postprandial blood glucose and other blood glucose values. Relevant tests should be completed to comprehensively assess the condition. It is recommended to go to the hospital when there is an elevated glycosylated hemoglobin and ask the doctor to make a judgment and give treatment measures.
