What is the normal fasting blood glucose range?

• A. 60–80 mg/dL
• B. 80–110 mg/dL
• C. 100–140 mg/dL
• D. 70–99 mg/dL

Answer: (D)

Normal fasting blood glucose reflects the baseline level of glucose after not eating for at least 8 hours. For a person without diabetes, this baseline is typically between 70 and 99 mg/dL. Values below 70 mg/dL suggest hypoglycemia risk, while higher ranges enter prediabetes or diabetes categories (100–125 mg/dL is impaired fasting glucose, and 126 mg/dL or higher on two occasions indicates diabetes). Among the options, 70–99 mg/dL is the range that best represents normal fasting glucose.
