what is the range of normal blood sugar

The normal range for blood sugar levels varies depending on when the test is taken:

• Fasting Blood Sugar (before eating): 70–99 mg/dL (3.9–5.5 mmol/L)
• Postprandial Blood Sugar (2 hours after eating): Less than 140 mg/dL (7.8 mmol/L)
• Random Blood Sugar: Typically less than 140 mg/dL (7.8 mmol/L)

These ranges are general guidelines. For a precise diagnosis or personalized advice, consult a healthcare professional.
