Hemoglobin A1c Test

The Hemoglobin A1c test measures the average level of glucose (sugar) in your blood over the past two to three months. It works by looking at how much sugar has attached to hemoglobin, a protein in red blood cells that carries oxygen. This test is commonly used to diagnose and monitor diabetes. A higher A1c level indicates poorer blood sugar control, which can lead to complications if not managed properly. The results help healthcare providers assess how well diabetes is being managed and make necessary treatment adjustments.
