To diagnose type 2 diabetes, healthcare providers typically use one or more of the following tests:

  • A1C Test: Measures your average blood sugar levels over the past 2-3 months. A result of 6.5% or higher indicates diabetes.
  • Fasting Plasma Glucose (FPG) Test: Requires fasting overnight. A blood sugar level of 126 mg/dL or higher suggests diabetes.
  • Oral Glucose Tolerance Test (OGTT): Involves drinking a sugary solution and testing blood sugar levels after 2 hours. A level of 200 mg/dL or higher indicates diabetes.
  • Random Blood Sugar Test: A blood sugar level of 200 mg/dL or higher, regardless of when you last ate, may indicate diabetes.

If you have symptoms like increased thirst, frequent urination, or unexplained weight loss, consult your doctor for testing. Early diagnosis and management are crucial for preventing complications.
