Correct: Hemoglobin A1c (HbA1c) measures the average glucose level attached to hemoglobin in red blood cells over the last three months.

American Diabetes Association recommends an A1c target of less than 7% to manage diabetes effectively and minimize complications.

Targets may be personalized based on individual health conditions, duration of diabetes, age, life expectancy, pregnancy and other factors. It's important for you to discuss the specific A1c goals with your healthcare provider.
