What does the term "A1C" refer to in diabetes management?

The term "A1C" refers to a blood test that measures the average blood glucose levels over the past two to three months. This test provides valuable information about a person's long-term glucose control and is crucial in diabetes management. It indicates how well blood sugar levels have been controlled, helping healthcare providers assess the effectiveness of a patient's diabetes treatment plan.

A1C is expressed as a percentage; the higher the percentage, the poorer the blood glucose control. This makes it a vital marker for both diagnosing diabetes and monitoring ongoing management, allowing adjustments in medication or lifestyle changes as necessary. The focus on long-term trends, rather than a single reading, distinguishes it from other measurements, making it a cornerstone of effective diabetes care.
