22.How does my doctor confirm the diagnosis of diabetes?
Your doctor will perform one of the standard measurements for the diagnosis of diabetes approved by the accepted authoritative body in whichever part of the world you live. In the United States, this is generally set by the American Diabetes Association (ADA) and is accepted by most practitioners, insurers, and health providers as valid.
The most current ADA criteria for the diagnosis of diabetes are shown in Table 1 (see Question 9). Your doctor may or may not ask you to fast prior to measuring the blood glucose or he or she may perform a standard 2-hour test known as the oral glucose tolerance test.
