When many diabetic patients go to the hospital for examination, doctors will ask them to do glycated hemoglobin test, so what is the significance of measuring glycated hemoglobin in the end? 1.Evaluate the overall control of blood sugar Glycated hemoglobin can reflect the average level of blood sugar control in the past 2 to 3 months, and is not affected by an occasional increase or decrease in blood sugar. 2.Discovery of existing problems If the patient’s blood glucose is frequently monitored shows good control, but the glycosylated hemoglobin is high, it is necessary to consider whether the usual monitoring of blood glucose is not comprehensive enough, such as only measuring fasting blood glucose and ignoring postprandial blood glucose. For example, if a diabetic patient’s glycosylated hemoglobin is regularly monitored at 6% to 7%, but the latest one is 8.2%, this indicates that the previous treatment plan can no longer control blood glucose well and needs to be readjusted. Tips If a diabetic patient has reached the blood glucose control standard and is relatively stable, then hemoglobin should be tested at least twice a year. For those who need to change their treatment regimen or whose glycemic control status is unstable and those who are on insulin therapy, glycated hemoglobin should be measured every 3 months.
