Testing for prediabetes

The only way to know for sure that you have prediabetes is by a blood test.

First, find out if you are at risk for prediabetes:

If you are at risk for prediabetes, talk to your doctor about getting a laboratory blood test. There are several different blood tests:

  • Diabetes Risk Panel : Predicts how likely you are to get diabetes in your lifetime
  • Diabetes Risk Panel with Score : Predicts how likely you are to get diabetes within eight years
  • ASCVD Risk Panel with Scores : Predicts how likely you are to get atherosclerotic cardiovascular disease, a disease that clogs the arteries in your heart. This is important because many patients with diabetes get strokes, heart attack, and heart disease

If you don't have prediabetes, your doctor may still recommend you get tested in the future–maybe in a few years–to make sure things don’t get worse.

If you do have prediabetes:

  • Talk to your doctor about your diagnosis
  • You may need to take more tests
  • Your doctor might recommend medication

For those with prediabetes, the Centers for Disease Control and Prevention (CDC) recommends joining a lifestyle-change program to help encourage healthy eating, increase physical activity, and lose weight.
