The HbA1c test measures the percentage of red blood cells that have glucose attached to their hemoglobin. Hemoglobin is the protein in red blood cells that carries oxygen from the lungs to the rest of the body. A pathologist takes a blood sample from a vein in your arm. You don't need to fast before the test.
