Diagnosing Type 2 Diabetes and Identifying Prediabetes

The American Diabetes Association and the World Health Organization have established uniform criteria for diagnosing type 2 diabetes and identifying people with prediabetes. Type 2 diabetes can be diagnosed in one of four ways: measuring A1C, fasting plasma glucose, and random plasma glucose levels or performing an oral glucose tolerance test. Risk assessment tools are available to determine whether an individual should be tested for diabetes or prediabetes.
