What fasting blood glucose range is normal?

What fasting blood glucose range is normal?

• A. 5.6-6.9 mmol/L
• B. <5.6 mmol/L
• C. ≥7.0 mmol/L
• D. 5.0-5.5 mmol/L

Answer: (B)

Understanding fasting glucose thresholds shows how categories are defined after a period without eating. Normal fasting glucose is below 5.6 mmol/L. When the value is 5.6 to 6.9 mmol/L, that indicates impaired fasting glucose, often called prediabetes. A level of 7.0 mmol/L or higher meets criteria for diabetes. So the option that states normal is less than 5.6 mmol/L best fits the standard definition, because it uses the official cutoff that separates normal from elevated fasting glucose. The other ranges place you in prediabetes or diabetes, or merely describe a portion of the normal range.
