Which fasting blood glucose level is considered elevated in this context?

• A. < 100 mg/dL
• B. 100 mg/dL
• C. Between 90 and 99 mg/dL
• D. > 100 mg/dL

Answer: (D)

Elevated fasting glucose means the value exceeds the normal upper limit. The commonly accepted normal range for fasting blood glucose is under 100 mg/dL. A reading of 90–99 mg/dL is still considered normal, while 100 mg/dL sits at the threshold and is often described as impaired fasting glucose in many guidelines. When the result is greater than 100 mg/dL, it clearly indicates that fasting glucose is elevated. Therefore, any value above 100 mg/dL best captures the idea of an elevated fasting glucose.
