A1c reflects the (predicted) average blood sugar level over two to three months. Specifically, the A1c predicts what percentage of hemoglobin — a protein in red blood cells that carries oxygen — is coated with sugar (glycated). The higher the percentage, the poorer the blood sugar control and the higher the risk of developing (pre)diabetes or complications of diabetes. For someone who doesn't have diabetes, a normal A1c level is below 5.7 percent. If the A1c level is between 5.7 and 6.4 percent, it is considered prediabetic, which means there is a high risk of developing diabetes in the future.
