Glycated hemoglobin

Glycated hemoglobin (sometimes called HbA1c) carries oxygen to the cells of the body. 

The level of glycated hemoglobin and the level of glucose in the blood are closely related. The higher the level of glycated hemoglobin in the blood, the higher the average blood glucose level.           

The glycated hemoglobin test is used to assess glycemic control over a period of two to three months, especially in people with diabetes. Diabetes is considered to be well-controlled if the HbA1c level is less than or equal to 7%.      

A glycated hemoglobin test is performed by taking a blood sample, which is then analyzed in a medical laboratory.
