If you have diabetes, you know all about the A1C test that tells you your average blood glucose levels over the past two to three months. An A1C level of 6.5-percent is a factor that helps diagnose diabetes. A recent study has found though that the A1C test may also be helpful in preventing diabetes in those at high risk for diabetes such as those who are overweight or obese. Those who have pre-diabetes will have an A1C level between 5.7 and 6.4-percent. Knowing these test results can help those at risk prevent diabetes and make lifestyle changes to improve the future of their health!
