Diabetes is diagnosed based on specific blood glucose levels. Here are the key thresholds:

- Normal: Less than 100 mg/dL
- Prediabetes: 100–125 mg/dL
- Diabetes: 126 mg/dL or higher
-
A1C Test:
- Normal: Below 5.7%
- Prediabetes: 5.7% to 6.4%
- Diabetes: 6.5% or higher
-
Oral Glucose Tolerance Test (OGTT):
- Normal: Less than 140 mg/dL
- Prediabetes: 140–199 mg/dL
- Diabetes: 200 mg/dL or higher
