The normal range for blood sugar levels in adults varies depending on the timing of the test:
- Fasting Blood Sugar (before eating): 70–99 mg/dL (3.9–5.5 mmol/L)
- Postprandial (2 hours after eating): Less than 140 mg/dL (7.8 mmol/L)
- A1C Test (average over 2–3 months): Below 5.7%
These ranges are general guidelines. Consult your healthcare provider for personalized targets, especially if you have diabetes or prediabetes.
