Diabetes is typically diagnosed through blood tests that measure blood sugar levels. The following are key indicators:
-
A1C Test:
- Normal: Below 5.7%
- Prediabetes: 5.7% to 6.4%
- Diabetes: 6.5% or above
-
Fasting Plasma Glucose (FPG) Test:
- Normal: Less than 100 mg/dL
- Prediabetes: 100 to 125 mg/dL
- Diabetes: 126 mg/dL or higher
-
Oral Glucose Tolerance Test (OGTT):
- Normal: Less than 140 mg/dL
- Prediabetes: 140 to 199 mg/dL
- Diabetes: 200 mg/dL or higher
-
Random Blood Sugar Test:
- Diabetes: 200 mg/dL or higher, especially if accompanied by symptoms like increased thirst, frequent urination, or fatigue.
If your results fall into the prediabetes or diabetes range, your healthcare provider may recommend further testing or a treatment plan.
