What is the normal blood glucose range?

• A. 60-90 mg/dL
• B. 90-120 mg/dL
• C. 100-140 mg/dL
• D. 70-110 mg/dL

Answer: (D)

Normal blood glucose is the level at which the body keeps circulating glucose in a healthy, regulated range when you’re fasting. In healthy individuals, fasting plasma glucose typically sits around 70 to 110 mg/dL. This window reflects stable regulation by insulin and other hormones, without the influence of recent meals. Values below about 70 mg/dL can lead to symptoms of hypoglycemia, while measurements persistently above roughly 125 mg/dL suggest impaired glucose regulation or diabetes, so 70–110 mg/dL best matches what’s considered normal fasting glucose. The other ranges either fall outside this typical fasting window or are higher than normal fasting values. For context, after a meal, glucose can rise, but a normal 2-hour postprandial value is usually under about 140 mg/dL.
