Glycated hemoglobin A1c (HbA1c) is a form of hemoglobin that is chemically linked to a sugar. The glycated hemoglobin test measures the concentration of glycated A1c hemoglobin by evaluating the average level of glucose in the blood over the past 2 to 3 months. Hemoglobin is an oxygen-carrying protein found inside red blood cells. Although several normal and variant hemoglobin are known, the most common form, accounting for 95~98%, is hemoglobin A.
When glucose circulates in the blood, some of it naturally binds to hemoglobin A. A molecule that combines glucose and hemoglobin is said to be glycated. The higher the blood glucose level, the more glycated hemoglobin is produced. Once glucose binds to the hemoglobin, it remains bound until the end of the lifespan of red blood cells – which is normally 120 days. HbA1c test is used to diagnose, detect and monitor treatment of diabetes by assessing glucose levels over a period of time.
