Blood tests are used to diagnosis prediabetes because early in the disease type 2 diabetes may have no symptoms. All diabetes blood tests involve drawing blood at a health care provider’s office or commercial facility and sending the sample to a lab for analysis. Lab analysis of blood is needed to ensure test results are accurate. Glucose measuring devices used in a health care provider’s office, such as finger—stick devices, are not accurate enough for diagnosis but may be used as a quick indicator of high blood glucose.
In June 2009, an international committee composed of experts from the American Diabetes Association, the European Association for the Study of Diabetes and the International Diabetes Federation recommended that prediabetes testing include the:
- Fasting Plasma Glucose (FPG)
- Oral Glucose Tolerance Test (OGTT)
- Hemoglobin A1C (average blood sugar) Test
