Which level of HGB A1C indicates well-controlled diabetes?

A hemoglobin A1C level of less than 7% is widely recognized as the target goal for individuals with diabetes to indicate well-controlled blood sugar levels. This threshold is based on guidelines from various diabetes associations, which suggest that maintaining an A1C below this level can reduce the risk of diabetes-related complications.

When the A1C is lower than 7%, it reflects that the average blood glucose levels over the past two to three months have been kept in a range that is less likely to harm the body and lead to the long-term effects of diabetes, such as neuropathy, nephropathy, and retinopathy. Thus, achieving this target is key to managing diabetes effectively and improving overall health outcomes.

The other options suggest either levels that are too low or above the recommended threshold, which would not reflect good control of diabetes.
