Type 2 diabetes is typically diagnosed through one or more of the following blood tests:

  • A1C Test: Measures your average blood sugar level over the past 2-3 months. A result of 6.5% or higher indicates diabetes.
  • Fasting Plasma Glucose (FPG) Test: Measures blood sugar after an overnight fast. A result of 126 mg/dL or higher indicates diabetes.
  • Oral Glucose Tolerance Test (OGTT): Measures blood sugar before and 2 hours after drinking a sugary drink. A result of 200 mg/dL or higher after 2 hours indicates diabetes.
  • Random Plasma Glucose Test: Measures blood sugar at any time, regardless of when you last ate. A result of 200 mg/dL or higher, along with symptoms of diabetes, indicates diabetes.

If you have symptoms of diabetes, such as increased thirst, frequent urination, or unexplained weight loss, your doctor may use one or more of these tests to confirm a diagnosis.
