HbA1c (Glycated Hemoglobin) Test – Hyderabad

The HbA1c test, also called the glycated hemoglobin test, evaluates your average blood glucose levels over the past two to three months. Unlike a fasting glucose test that measures blood sugar at a single moment, HbA1c shows long-term glucose exposure by measuring how much sugar has attached to hemoglobin in your red blood cells. This makes it a valuable tool for diagnosing, monitoring, and managing diabetes.^:contentReference[oaicite:0]{index=0}

How the HbA1c Test Works

When glucose circulates in the bloodstream, it binds to hemoglobin, a protein in red blood cells that carries oxygen. Because red blood cells live for about three months, the percentage of glycated hemoglobin reflects average blood sugar during that period. A higher HbA1c percentage indicates higher long-term blood glucose levels.^:contentReference[oaicite:1]{index=1}

Who Should Get This Test?

• People diagnosed with diabetes to regularly monitor glucose control.
• Individuals at risk of diabetes due to family history, weight, or lifestyle.
• Those with prediabetic blood sugar levels to track progression.

The HbA1c test helps your healthcare provider assess how well your blood sugar levels have been managed over time and adjust treatments accordingly. It is commonly recommended at least twice a year for most people with diabetes and more often if treatment changes or control is poor.^:contentReference[oaicite:2]{index=2}

Test Preparation

You do not need to fast for the HbA1c test. It can be performed any time of the day, as no special preparation is required. If you are changing medications or have specific health concerns, discuss them with your healthcare provider before testing. ^:contentReference[oaicite:3]{index=3}

Understanding Normal Ranges

HbA1c results are reported as a percentage representing the proportion of glycated hemoglobin in your blood. Interpreting these values helps determine risk levels for diabetes and prediabetes. ^:contentReference[oaicite:4]{index=4}
