Type 2 diabetes can be diagnosed using several tests. Here are the most common methods:
-
A1C Test:

- 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.
- 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 sugary drink.
- Normal: Less than 140 mg/dL
- Prediabetes: 140 to 199 mg/dL
- Diabetes: 200 mg/dL or higher
-
Random Plasma Glucose Test:
- Measures blood sugar at any time, regardless of when you last ate.
- Diabetes: 200 mg/dL or higher, especially if accompanied by symptoms like increased thirst, frequent urination, or fatigue.
