The HbA1c test, also known as the glycated hemoglobin test, measures the average blood sugar levels over the past two to three months. It provides an indication of how well diabetes is being managed over a longer period compared to daily blood glucose tests. The HbA1c test is an essential tool for diagnosing diabetes and prediabetes, monitoring long-term blood glucose control, and predicting the risk of diabetes-related complications. It provides valuable information that helps healthcare providers and patients manage diabetes more effectively, adjust treatment plans, and set appropriate health goals. Regular HbA1c testing is crucial for maintaining optimal blood sugar levels and preventing the long-term complications associated with diabetes.
