Many diagnostic tests available today can tell doctors if you have
prediabetes, a condition that often occurs with insulin resistance and can lead
to type 2 diabetes. Your doctor will decide which diabetes screening test is
best for you based on your medical history, diabetes risk and whether you have
diabetes symptoms.
All of the diabetes screening tests listed below, which involve taking a
blood sample to measure your blood sugar levels, are performed in your doctor's
office or in a lab.
- A1c test
- Random blood sugar test
- Fasting blood sugar test
- Glucose tolerance test
If you're diagnosed with prediabetes, you'll work with your doctor to develop
a plan for diabetes education, exercise and a glycemic diet to delay or prevent
type 2 diabetes.
