Diabetic Diagnosis: How to Read Your Numbers

Know the Numbers

According to the American Diabetes Association's Standards of Medical Care, these numbers should be used to diagnose pre-diabetes and type 2 diabetes. The ADA suggests everyone over age 45 be checked every three years -- especially if your body mass index (BMI) is over 25. People with a family history of diabetes should be tested at a younger age and more frequently.
