The normal range for blood glucose levels varies depending on whether you are fasting or have recently eaten. Here are the general guidelines:
-
Fasting Blood Glucose (no food for at least 8 hours):
- Normal: 70–99 mg/dL
- Prediabetes: 100–125 mg/dL
- Diabetes: 126 mg/dL or higher
-
Postprandial Blood Glucose (2 hours after eating):
- Normal: Less than 140 mg/dL
- Prediabetes: 140–199 mg/dL
- Diabetes: 200 mg/dL or higher
-
A1C Test (average blood glucose over 2–3 months):
- Normal: Below 5.7%
- Prediabetes: 5.7% to 6.4%
- Diabetes: 6.5% or higher
These ranges are used to diagnose and monitor diabetes and prediabetes. Always consult your healthcare provider for personalized advice.
