4. The Role of HbA1c in Diabetes Diagnosis
In addition to monitoring long-term glucose control, HbA1c testing plays a vital role in diagnosing diabetes. The American Diabetes Association (ADA) includes HbA1c as one of the tests to diagnose prediabetes and type 2 diabetes. An HbA1c level of 6.5% or higher on two separate tests indicates that you have diabetes.
An HbA1c between 5.7% and 6.4% suggests prediabetes, a condition where blood sugar levels are higher than normal but not high enough yet to be diagnosed as diabetes. Identifying and addressing prediabetes is crucial as it offers an opportunity to make lifestyle changes that can help lower blood sugar and prevent or delay the onset of type 2 diabetes.
For those at risk of diabetes, an HbA1c test is a tool that can provide early warning signs. Early detection is crucial for managing the condition effectively and preventing complications. Knowing your HbA1c levels allows you to take proactive steps in managing your health.
By providing a clear and objective measure of blood sugar control over time, HbA1c testing is invaluable in diagnosing and managing diabetes. It offers a unique perspective, complementing other tests and evaluations to provide a comprehensive view of an individual’s health. (4)
