What does HgbA1C measure?

HgbA1C, also known as hemoglobin A1C, specifically measures the average blood glucose (sugar) levels over the past two to three months. This is achieved by assessing the percentage of hemoglobin that has glucose attached to it, providing insights into a person's long-term glycemic control.

This test is particularly crucial in the management of diabetes, as it helps determine how well an individual's blood sugar levels are being controlled over time. While other tests may assess immediate blood sugar levels or other aspects of health, HgbA1C focuses uniquely on chronic blood sugar levels, making it a vital tool for diagnosing and monitoring diabetes.
