Diabetes is often diagnosed by measuring fasting glucose levels. If that value is lower than the value necessary to diagnose diabetes but your doctor suspects you still may have diabetes, an oral glucose tolerance test may be done. This is a special test that shows how well the body uses glucose.
Talk to your doctor about how often you should be tested. How frequently you are tested for diabetes depends on your age and risk factors for the condition.
