What is the Glycated Hemoglobin Test?

The glycated hemoglobin test, also called the HbA1c test, measures your average blood sugar over the past two to three months. Doctors use this test to check how well your blood sugar is controlled. Unlike daily blood sugar checks, this test gives a bigger picture. For people with diabetes, it is an important tool for diabetes monitoring and long-term health.

Why is the Glycated Hemoglobin Test Important?

First, the glycated hemoglobin test helps find out if your blood sugar is too high or too low over time. This is important because high blood sugar can damage your heart, eyes, and kidneys. Also, the test helps your doctor see if your diabetes treatment is working. According to the CDC, keeping your HbA1c in a healthy range lowers your risk of problems from diabetes.

How is the Test Performed?

Getting a glycated hemoglobin test is simple. A healthcare worker takes a small blood sample, usually from your arm. You do not need to fast before this test. The sample goes to a lab, and you usually get results in a few days. Because the test is quick and easy, many people find it less stressful than other blood tests.

Understanding Your Results

Once you get your HbA1c test results, it is important to know what they mean. Here is a simple guide:

  • Below 5.7%: Normal blood sugar
  • 5.7% to 6.4%: Higher risk for diabetes (pre-diabetes)
  • 6.5% or higher: Diabetes

    • However, your doctor may set a different target for you. For many people with diabetes, the goal is to keep HbA1c below 7%. Still, your target may change based on your age, health, or other factors. Always talk to your doctor about your results.

    Who Should Get Tested?

    Many people benefit from the glycated hemoglobin test. For example, you should get tested if:

  • You have diabetes or pre-diabetes
  • Your doctor wants to check your blood sugar control
  • You have risk factors, like being overweight or having a family history of diabetes

    • Most adults with diabetes need this test at least twice a year. Some may need it more often, especially if their treatment changes.

    Tips for Accurate Results

    To get the best results from your HbA1c test, follow these tips:

  • Tell your doctor about any health changes or new medicines
  • Let the lab know if you have anemia or blood disorders, as these can affect results
  • Keep regular testing appointments for better diabetes monitoring

    • Because some conditions can change your results, always share your full health history with your doctor.
