Basic Way to Diagnose Diabetes and Prediabetes
How could people define if they are prediabetes and diabetes, this page will guide you the basic way to diagnose diabetes and prediabetes.
The first straight way is blood tests which are used to diagnosis diabetes and 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.
Testing enables health care providers to find and treat diabetes before complications occur and to find and treat prediabetes, which can delay or prevent type 2 diabetes from developing.
All the following tests can be used for diagnosis:
- an A1C test, also called the hemoglobin A1c, HbA1c, or glycohemoglobin test
- a fasting plasma glucose (FPG) test
- an oral glucose tolerance test (OGTT)
- Not all tests are recommended for diagnosing all types of diabetes. See the individual test descriptions for details.
- Another blood test, the random plasma glucose (RPG) test, is sometimes used to diagnose diabetes during a regular health checkup. If the RPG measures 200 micrograms per deciliter or above, and the individual also shows symptoms of diabetes, then a health care provider may diagnose diabetes.
