HbA1c (glycated hemoglobin)

HbA1c, or glycated hemoglobin, is a measure that reflects your average blood sugar levels over the past two to three months. This test indicates how well the blood sugar has been controlled in people with diabetes, offering a long-term perspective. Hemoglobin is a protein in your red blood cells that carries oxygen. When glucose, or sugar, in the blood attaches to this protein, it becomes "glycated." The more glucose in the bloodstream, the higher the level of glycated hemoglobin.

The HbA1c test is crucial for managing diabetes. Unlike daily blood sugar tests that offer a snapshot of sugar levels at a specific time, HbA1c provides a broader view, showing how well blood sugar levels have been maintained over weeks and months. It can help doctors prescribe or adjust medications and recommend lifestyle changes as needed to manage blood sugar more effectively.

For people without diabetes, the test can also indicate the risk of developing diabetes, prompting proactive lifestyle changes. Understanding your HbA1c level can empower you to take control of your health by guiding decisions around diet, exercise, and other lifestyle factors.
