First, let’s clarify the concept of glycated hemoglobin, which is a product of the combination of blood glucose and hemoglobin in the blood. The first thing you need to do is to make sure that you have a good idea of what you are doing. Therefore, glycosylated hemoglobin is a good indicator of the average blood glucose level in the body over the past 2-3 months.
Glycosylated hemoglobin is useful for guiding clinical use in patients with diabetes who are on hypoglycemic medications. The normal value of glycated hemoglobin is between 4% and 6%. The World Medical Association currently includes glycosylated hemoglobin greater than 6.5% as one of the diagnostic criteria for diabetes mellitus. However, glycosylated hemoglobin is not the only indicator for the diagnosis of diabetes, but should be combined with fasting glucose values and glucose tolerance results. So with a high glycosylated hemoglobin, it is important to monitor fasting blood glucose levels.
