What does an A1C level of 7.0 correlate to regarding mean glucose levels?

An A1C level of 7.0% typically correlates with a mean glucose level of approximately 154 mg/dL. This value is derived from the conversion established by the American Diabetes Association, which indicates that for every 1% increase in A1C, the average blood glucose level increases by about 28–30 mg/dL. Therefore, an A1C of 7.0% represents an average glucose level that falls within the range of 150–160 mg/dL.

Given that option A specifies less than 150 mg/dL, it is not the most accurate representation of the correlation between an A1C of 7.0% and average glucose levels. The correct understanding is that an A1C of 7.0% more closely relates to an average of about 154 mg/dL, putting it above the threshold of 150 mg/dL stated in option A.

Instead, a more accurate choice would be one that acknowledges that a mean glucose level corresponding to this A1C value would be closer to the range of 154 mg/dL, suggesting that options which indicate higher mean glucose levels are more appropriate.
