Have Your Blood Glucose Checked

Your doctor can test your fasting blood glucose.

Check the chart to see if your blood glucose level is normal.

Juan says: "My doctor told me I need to know the ABCs of diabetes control to prevent and control type 2 diabetes."

What Are the ABCs of Diabetes Control?

  • A is for the A1C test. This test measures how your blood glucose has been for the last 3 months. It lets you know if your blood glucose has been under control. Get this test done at least twice a year.
    Number to aim for: less than 7%

  • B is for blood pressure. The higher your blood pressure, the harder your heart has to work. Get your blood pressure checked at every doctor's visit.
    Numbers to aim for: below 130/80 mmHg

  • C is for cholesterol. "Bad" cholesterol—or LDL—builds up and clogs your arteries. Get your blood cholesterol tested at least once a year.
    Number to aim for: below 100 mg/dL

Be Sure To Ask Your Doctor

  • What are the results of my A1C, blood pressure, and cholesterol tests?
  • If my numbers are not normal, what actions should I take to lower my ABC numbers?
  • How can I find a local diabetes program for education and support?
