Why do I need an HbA1C test?

The Centers for Disease Control (CDC) recommends A1C testing for diabetes and prediabetes if:

• You are over age 45.
  • If your results are normal, you should repeat the test every 3 years.
  • If your results show you have prediabetes, you will usually need to be tested every 1 to 2 years. Ask your provider how often to get tested and what you can do to reduce your risk of developing diabetes.
  • If your results show you have diabetes, you should get an A1C test at least twice a year to monitor your condition and treatment.
• You are under 45 and are more likely to develop diabetes because you:
  • Have prediabetes.
  • Are overweight or have obesity.
  • Have a parent or sibling with type 2 diabetes.
  • Have high blood pressure or high cholesterol levels.
  • Have heart disease or have had a stroke.
  • Are physically active less than 3 times a week.
  • Have had gestational diabetes (diabetes during pregnancy) or given birth to a baby over 9 pounds.
  • Are African American, Hispanic or Latino, American Indian, or an Alaska Native person. Some Pacific Islander and Asian American people also have a higher risk of developing diabetes.
  • Have polycystic ovarian syndrome (PCOS).
