what is a good glucose reading

A good glucose reading depends on when the measurement is taken:

• Fasting (before meals): 70–99 mg/dL (3.9–5.5 mmol/L) is considered normal.
• Postprandial (1–2 hours after eating): Less than 140 mg/dL (7.8 mmol/L) is ideal.
• A1C Test: Below 5.7% is normal, 5.7%–6.4% indicates prediabetes, and 6.5% or higher suggests diabetes.

For people with diabetes, target glucose levels may vary based on individual health conditions and treatment plans. Always consult your healthcare provider for personalized targets.
