Glycated Hemoglobin

Glycated hemoglobin, often called HbA1c, is a blood test that shows your average blood sugar levels over the past two to three months. It measures how much sugar has attached to your hemoglobin, a protein in red blood cells that carries oxygen. Higher HbA1c levels indicate higher blood sugar levels, which can suggest diabetes or poor blood sugar control in people already diagnosed. This test helps healthcare providers assess how well someone is managing their blood sugar and guides treatment decisions to reduce the risk of complications.
