what is the normal level of glucose in the blood

The normal level of glucose in the blood varies depending on when the test is taken:

• 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)
• Random Blood Sugar: Typically less than 140 mg/dL (7.8 mmol/L)

These values are general guidelines. Consult your healthcare provider for personalized targets, especially if you have diabetes or prediabetes.
