What is the normal fasting blood glucose level?

• A. 75 mg/dL
• B. 85 mg/dL
• C. 95 mg/dL
• D. 105 mg/dL

Answer: (B)

Normal fasting blood glucose refers to the level in the blood after no food for about 8 hours. The typical reference range is roughly 70 to 99 mg/dL. Values at or above 100 mg/dL on a fasting test are considered elevated and may indicate impaired fasting glucose or a higher diabetes risk if persistent. Among the given numbers, 85 mg/dL sits comfortably within the normal range and represents a typical normal fasting reading. A value like 105 mg/dL would be elevated and not normal.
