Hemoglobin A1c (HbA1c) molecules attach to glucose in your bloodstream and can be used to estimate how much glucose, or blood sugar, has been in your blood over the past 3 months. This test can be used by a healthcare provider along with other factors to evaluate your risk of developing prediabetes and type 2 diabetes.

Hemoglobin A1c (HbA1c) test measures the percentage of hemoglobin A molecules attached to glucose in your bloodstream. The higher the percentage of HbA1c, the higher your blood sugar levels have been over the last 3 months. Certain factors and health conditions can cause HbA1c test results to be higher or lower independent of diabetes. We encourage you to share your result with your own primary care provider, who can consider your individual factors when evaluating your test results and recommending the appropriate next steps.
