When should I get tested?

Young adults with multiple risk factors, such as obesity or a family history of diabetes, should get tested. Overweight children, especially if they belong to high-risk groups such as Hispanics or African Americans, should be screened for prediabetes. Always consult with your health care provider to determine if testing is recommended in your case.

When risk factors are not present, The American Diabetes Association recommends that adults be testedd for diabetes starting at age 45.

There are three blood tests that are used to test for diabetes and prediabetes:

Fasting Plasma Glucose Test (FPG)
This test measures blood glucose (blood sugar) in a person who has been fasting (not eating) for at least eight hours, and is the most common test used to diagnose type 2 diabetes.

Oral Glucose Tolerance Test (OGTT)
This test measures blood glucose after a person fasts (doesn't eat) for at least eight hours and two hours after the person drinks a glucose-containing beverage. This test is also used to diagnose gestational diabetes (diabetes during pregnancy).

A1C Test
This test measures your average blood glucose levels over two to three months. It tracks the amount of glycated hemoglobin (also called HbA1c) in the blood.
