What Is an A1C Test?
An A1C test is a type of blood test that measures the level of hemoglobin A1C in the blood. Hemoglobin plays an important role in red blood cells, which transport oxygen and nutrients to other body cells. The test is based on the attachment of glucose with haemoglobin. Therefore, the results can provide information about blood sugar levels over the last few months. Most doctors often use this test to diagnose or manage prediabetes and diabetes. [1]
