Your Average Glucose Value over a 2-3 Month Period
  • Your A1C score is an estimate of your average blood sugar level over the last 2 to 3 months. Approximately half of the score comes from the last 30 days. [2]
  • If your A1C is high, you and your doctor may discuss changes to your diet, exercise and possibly medications to help reduce your A1C, which could help reduce your risks.
  • It’s been shown that a 1% reduction in A1C lowers risk of complications such as eye, kidney and nerve disease by 40%.[3]
