Glycated Hemoglobin (HbA1c) Test — What It Measures and Why It Matters

What is the Glycated Hemoglobin (HbA1c) Test?

The glycated hemoglobin test, also known as the HbA1c test, measures your average blood sugar over the past two to three months. This test helps doctors check how well your blood sugar is controlled. Unlike daily blood sugar checks, the HbA1c test gives a bigger picture. For people with diabetes, this test is very important. It can also help diagnose diabetes or prediabetes in people who do not have symptoms.

Why is the HbA1c Test Important?

First, the HbA1c test helps track long-term blood sugar control. This is key for people with diabetes. High blood sugar over time can harm your heart, eyes, kidneys, and nerves. Because of this, doctors use the HbA1c test to guide treatment. The World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC) both recommend this test for diabetes diagnosis and management. In addition, it helps spot problems early, so you can make changes before health issues develop.

How is the Test Performed?

Getting an HbA1c test is simple. Usually, a nurse or lab technician takes a small blood sample from your arm. You do not need to fast before this test. After the blood is drawn, it is sent to a lab for analysis. Results are often ready within a few days. Because the test is quick and easy, many people find it less stressful than other blood sugar tests.

Understanding Your HbA1c Results

Once you get your results, it is important to know what the numbers mean. The HbA1c result is given as a percentage. Here is a simple guide:

Below 5.7%: Normal blood sugar

5.7% to 6.4%: Prediabetes (higher risk for diabetes)

6.5% or higher: Diabetes

For most people with diabetes, doctors aim for an HbA1c below 7%. However, your target may be different. Always talk to your doctor about your personal goal. If your number is high, it means your blood sugar has been high over the past few months. Lower numbers show better blood sugar control.

Who Should Get Tested?

Many people can benefit from the glycated hemoglobin test. You should consider the test if you:

Have symptoms of high blood sugar, such as thirst or frequent urination

Have risk factors for diabetes, like being overweight or having a family history

Are over age 45 (the CDC recommends regular screening)

Already have diabetes and need to monitor your control

Even if you feel healthy, regular testing can help catch problems early. Early action can prevent serious health issues later.
