The Hemoglobin A1c (HbA1c) test measures the percentage of hemoglobin in the blood that has glucose attached, reflecting average blood sugar levels over the past 2–3 months. This test provides a long-term view of blood glucose control.
It is commonly used to screen for and monitor diabetes and prediabetes and to assess how well blood sugar levels are being managed over time. A1c results help guide treatment decisions and are often interpreted alongside fasting glucose or other metabolic tests.
