Hemoglobin A1c (HbA1c) is a blood test that measures average glycemic (blood sugar) concentration over the last couple of months. This test is a good reflection of your average blood sugar trend and it is useful in diagnosing type 2 diabetes.
The table below reflects blood sugar trend and it's indication for diabetes:
Those with type 2 diabetes should aim for an A1c <7.0%.
I recommend checking your HgA1c annually to monitor your risk for developing type 2 diabetes. By doing this, you can make lifestyle changes (like eating better and exercising more) to improve your HbA1c lab and decrease your risk for developing type 2 diabetes.
Eat Well, Live Well.
