The HbA1c test is a blood test that measures the average level of blood sugar over the past 2-3 months. It is commonly used to diagnose and monitor diabetes. This article will provide a comprehensive guide on the HbA1c test, including its normal range, interpretation, and frequently asked questions.
Normal range of HbA1c:
The normal range for HbA1c is less than 5.7%. A result between 5.7% and 6.4% indicates prediabetes, while a result of 6.5% or higher indicates diabetes. It is important to note that these ranges may vary depending on the laboratory and the testing method used.
Interpretation of HbA1c test:
The HbA1c test provides an average of blood sugar levels over the past 2-3 months. It is a useful tool for monitoring blood sugar control in people with diabetes. If the HbA1c level is high, it means that the blood sugar level has been consistently high over the past few months, indicating poor diabetes management. In contrast, a low HbA1c level indicates good diabetes control.
