what range is normal blood sugar

Normal blood sugar levels vary depending on when you last ate. Here are the general ranges:

• 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 for adults without diabetes. If you have diabetes, your target ranges may differ, and you should follow your healthcare provider's recommendations.
