The hemoglobin is a very important protein of red blood cells, the main function is to bring oxygen throughout the body for the use of tissue and cells. And glycated hemoglobin (HbA1c) is the concentration of glucose attached to the hemoglobin, once the glucose attached to the hemoglobin is not easy to fall off until the red blood cell aging to death.
If the concentration of blood glucose is higher, the higher level of glycated hemoglobin (HbA1c) is. And the general lifetime of red blood cell is 120 days, so the determination of glycated hemoglobin (HbA1c) is able to reflect the state of blood glucose control for past 2-3 months. Therefore, the measurement of glycated hemoglobin (HbA1c) can be only once in 2-3 months.
Measurements of level of blood glucose is very important for diabetes, blood glucose monitoring is a short period of time on behalf of the blood glucose control, but blood sugar is often affected by food, exercise, drugs, diseases and other factors, However, glycated hemoglobin (HbA1c) of the determination can be a long term of control situation of blood sugar.
People, who have Diabetes, need HbA1c test regularly to see if their levels are staying within range.It can tell if you need to adjust the treatment for Diabetes control.The HbA1c test is also used to diagnose Diabetes.
