There is no such thing as a glycated hemoglobin equivalent to blood glucose. Glycated hemoglobin of 6.3% reflects the level of glycemic control over the last 2 to 3 months and does not reflect instantaneous blood glucose levels.
Glycated hemoglobin (HbA1c) is the product of combining hemoglobin in red blood cells and sugar in serum through a non-enzymatic reaction, which can reflect the level of glycemic control in the last 2 to 3 months, but does not reflect the instantaneous level of blood glucose and the entire fluctuation of blood glucose, so there is no such thing as how much glycated hemoglobin is equivalent to blood glucose.
The normal range of glycosylated hemoglobin is 4% to 6%, glycosylated hemoglobin 6.3% is high, need to be combined with fasting blood glucose, postprandial blood glucose and other indicators to determine the existence of diabetes, can go to the hospital to further improve the glucose tolerance test and other related examinations.
Generally speaking, if the glycosylated hemoglobin is over 6.5% and there are symptoms of polyuria, polydipsia, polyphagia and weight loss, it is necessary to consider whether there is diabetes or not. In diabetic patients, the general control goal for glycosylated hemoglobin requires control to ≤7%.
Glycated hemoglobin of 6.3% should go to the hospital for further examination and treatment under the guidance of the doctor.
