how can you diagnose diabetes

Diabetes can be diagnosed through several tests, including:

• A1C Test: Measures your average blood sugar levels over the past 2-3 months. Results are interpreted as follows:

  • Normal: Below 5.7%
  • Prediabetes: 5.7% to 6.4%
  • Diabetes: 6.5% or above

• Fasting Plasma Glucose (FPG) Test: Measures blood sugar after an overnight fast. Results are interpreted as follows:

  • Normal: Less than 100 mg/dL
  • Prediabetes: 100 to 125 mg/dL
  • Diabetes: 126 mg/dL or higher

• Oral Glucose Tolerance Test (OGTT): Measures blood sugar before and 2 hours after drinking a glucose-rich drink. Results are interpreted as follows:

  • Normal: Less than 140 mg/dL
  • Prediabetes: 140 to 199 mg/dL
  • Diabetes: 200 mg/dL or higher

• Random Blood Sugar Test: Measures blood sugar at any time, regardless of when you last ate. A result of 200 mg/dL or higher suggests diabetes.

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