HbA1c (Glycated Hemoglobin) is a biomarker that reflects the average blood glucose levels over the past two to three months. It forms when glucose binds to hemoglobin in red blood cells and serves as a key indicator for long-term blood sugar control. Elevated HbA1c levels suggest poor glucose regulation and are commonly used to diagnose and manage diabetes.
A high HbA1c level typically indicates that an individual’s blood sugar levels have been consistently above the normal range for a prolonged period. This can suggest uncontrolled diabetes or a need to adjust the current diabetes management plan. It also increases the risk of diabetes-related complications, emphasizing the need for effective blood sugar control.
For individuals with diabetes, testing HbA1c levels is typically recommended every 3-6 months. This frequency can vary based on the type of diabetes and how well it’s being managed.
HbA1c tests are a key component in diagnosing diabetes, as they reflect long-term glucose levels rather than short-term or daily fluctuations.
No, daily blood sugar tests provide immediate, short-term glucose levels, while HbA1c reflects the average blood sugar levels over a few months. Both are important for comprehensive diabetes management.
