Which fasting blood sugar level result should be considered abnormal for a nondiabetic?

• A. 90 mg/dL
• B. 95 mg/dL
• C. 101 mg/dL
• D. 105 mg/dL

Answer: (C)

A fasting blood sugar level is used to assess how well the body regulates blood sugar levels. For a nondiabetic individual, normal fasting blood sugar levels typically range from 70 to 99 mg/dL. Values above this range can indicate potential issues with glucose metabolism. In the context of the provided options, a fasting blood sugar level of 101 mg/dL is the first reading that falls outside the normal range for nondiabetic individuals, marking it as abnormal. This level signals that the individual may be experiencing impaired fasting glucose or increased risk for developing diabetes, thus warranting further investigation or monitoring. The other levels presented (90 mg/dL, 95 mg/dL, and 105 mg/dL) either fall within the normal range or are right at the threshold of concern. Specifically, 90 and 95 mg/dL are well within the acceptable range, while 105 mg/dL represents an abnormal state more typical of a prediabetic condition rather than a nondiabetic fasting blood sugar level. However, 101 mg/dL is the earliest point at which the blood sugar level is already considered abnormal for someone who is not diabetic.
