Red blood cells live about three months.Glucose sticks to hemoglobin for as long as the red blood cells are alive.An A1C test measures the percentage of your red blood cells that have glucose-coated hemoglobin.Īn A1C test can show your average glucose level for the past three months because: As your blood glucose levels increase, more of your hemoglobin will be coated with glucose. Glucose in your blood sticks to hemoglobin, a protein in your red blood cells. As a result, glucose can't get into your cells, so your blood sugar levels increase. If you have diabetes your body doesn't make enough insulin, or your cells don't use it well. A hormone called insulin helps glucose get into your cells.
