How accurate is the a1c calculator?

The accuracy of the A1C calculator has been the subject of much debate among healthcare professionals. With its ability to estimate average blood sugar levels over a 2-3 month period, some argue that it may not always provide a true reflection of glucose control. Factors such as individual variations in red blood cell lifespan and interfering substances in the blood can affect the accuracy of the results. Despite these limitations, the A1C calculator remains a valuable tool for monitoring long-term blood sugar control in individuals with diabetes.
