HbA1c Test in Chennai
One good fasting reading does not mean your diabetes is controlled. The HbA1c test in Chennai shows the average of your blood sugar across the past two to three months, which is why doctors use it to diagnose diabetes and to judge whether treatment is actually working. There is no fasting and no fixed timing, so you can walk in on any day at either Unittas lab.

What is an HbA1c Test?
The HbA1c test is a simple blood test that shows your average blood sugar level over the past two to three months. Many people in Chennai take this test to check for diabetes, prediabetes, or to see how well their blood sugar is controlled. If you have a family history of diabetes, are overweight, or feel more thirsty and tired than usual, the HbA1c test can give you clear answers.
The HbA1c test (also called the A1C test or glycated haemoglobin test) measures how much sugar has stuck to the haemoglobin in your red blood cells. Red blood cells live for about two to three months. So the result shows your average blood sugar level over that time. A normal blood sugar test only shows the level at one moment. The HbA1c test gives a fuller picture of how your body has handled sugar over the past few months.
Why Might You Need an HbA1c Test?
Doctors often suggest this test when:
- You need screening for diabetes or prediabetes
- You already have diabetes and need to check how well treatment is working
- You have risk factors such as family history, excess weight, high blood pressure, or a history of diabetes in pregnancy
- You have symptoms like increased thirst, frequent urination, tiredness, blurred vision, or slow-healing cuts
How is the HbA1c Test Done?
The test is quick and easy:
- A trained staff member takes a small blood sample from a vein in your arm (or sometimes a finger prick).
- The sample goes to the lab for testing.
- Results are usually ready within a few hours to one day.
You do not need to fast. You can eat and drink as normal and take the test at any time of day.
Understanding Your HbA1c Results
The result is given as a percentage. Higher numbers mean higher average blood sugar. Use the HbA1c chart below as a simple guide:
| HbA1c Level | What It Means |
|---|---|
| Below 5.7% | Normal |
| 5.7% to 6.4% | Prediabetes |
| 6.5% or higher | Diabetes (usually needs a second test to confirm) |
Reference ranges vary between laboratories. Always read your report against the range printed on it, and with your doctor.
While the HbA1c normal range is below 5.7%, most adults with diabetes aim for an HbA1c below 7%. Your doctor may set a different target based on your age and health.
