HbA1c Test or Glycated Haemoglobin Test Overview

HbA1c or glycated haemoglobin is a blood test that reflects blood glucose levels in the last three months. It is useful for the diagnosis and management of diabetes and prediabetes. This test does not require fasting and is not affected by meals consumed immediately before the test (less prone to variation). In diabetic patients, high HbA1c levels mean a need for a change in treatment/ diet plan.

The higher the glucose levels, the more the glucose is attached to haemoglobin and the higher the HbA1c results. A higher HbA1c result indicates that the glucose levels have been higher than normal for the past 2 to 3 months.

Reasons for Undergoing the HbA1c Test

The HbA1c test, or HbA1c blood test, is a crucial tool for assessing long-term blood sugar levels, reflecting averages over the past two to three months. Unlike daily glucose tests, it measures the percentage of hemoglobin coated with sugar (glycated), providing valuable insights into blood sugar control.

Doctors recommend the HbA1c test for several reasons:

  1. Diabetes Screening: It’s commonly used to screen for type 2 diabetes, especially in individuals aged 45 and older or those with the risk factor like family history, even without any noticeable symptoms.
  2. Diabetes Diagnosis: The hemoglobin A1c test, or the HbA1c test helps confirm a diagnosis of type 2 diabetes in individuals with risk factors like obesity, high blood pressure, or elevated cholesterol levels.
  3. Diabetes Management: For those already diagnosed, the HbA1c test is essential for tracking blood sugar control and guiding treatment adjustments.

Overall, the HbA1c test plays a vital role in diabetes care and long-term health management.

Symptoms That Indicate the Need for an HbA1c Test

While not everyone with diabetes experiences noticeable symptoms, there are several warning signs that may suggest the need for an HbA1c test:

  • Increased thirst and frequent urination: High blood sugar levels can cause you to feel excessively thirsty and urinate more often than usual.
  • Persistent fatigue: If your body can't effectively use the glucose in your bloodstream for energy, you may feel tired and sluggish.
  • Blurred vision: Elevated blood sugar can cause fluid to shift into the lenses of your eyes, leading to temporary blurred or hazy vision.
  • Slow-healing wounds: High glucose levels can impair your body's ability to heal cuts, scrapes, and other injuries.
  • Frequent infections: Diabetes can weaken your immune system, making you more susceptible to infections like urinary tract infections and skin infections. Elevated blood sugar acts as a medium for growth and multiplication of organisms.

If you experience any of these symptoms, it's important to consult your doctor. They may recommend an HbA1c test to evaluate your blood sugar control and determine if lifestyle changes or medications are needed.

Common Factors That Raise the Risk of Diabetes

While anyone can develop diabetes, certain factors can increase your likelihood of being diagnosed with the condition:

  • Family history: If you have a parent or sibling with diabetes, your risk is higher.
  • Being overweight or obese: Excess body fat, especially around the waist, can lead to insulin resistance.
  • Physical inactivity: A sedentary lifestyle can make it harder for your body to regulate blood sugar levels.
  • Age: Your risk of type 2 diabetes increases as you get older, especially after age 45.

If you have one or more of these risk factors, it's crucial to get regular HbA1c tests to monitor your blood sugar levels and catch any potential issues early on. Your doctor can help you determine how often you should be tested based on your individual circumstances.

How the HbA1c Test Helps Monitor and Control Elevated Blood Sugar

The HbA1c test is an invaluable tool for managing diabetes because it provides a comprehensive picture of your blood sugar control over an extended period.   

Here's how it works:

  • Measures glycated haemoglobin: When glucose enters your bloodstream, it attaches to haemoglobin (the oxygen-carrying protein in red blood cells), forming glycated haemoglobin. The HbA1c test measures the percentage of this glycated haemoglobin.
  • Reflects average blood sugar: Since red blood cells live for about three months (120 days), the HbA1c test gives you and your doctor a good idea of your average glucose levels over that time frame.
  • Guides treatment decisions: Your HbA1c helps your doctor to determine if your current diabetes management plan is effective or if adjustments are needed to improve your blood sugar.

By getting regular HbA1c tests, you can stay on top of your diabetes and make informed decisions to prevent complications and maintain good health. Most people with diabetes should aim to get this diabetes monitoring test at least twice a year.

HbA1c Test Result Interpretation

Here is how you can understand what your HbA1c test results actually mean:

  • Normal (Below 5.7%): This indicates that your blood sugar is in a healthy range and you're not currently at risk for diabetes.
  • Prediabetes (5.7% to 6.4%): Prediabetes means your blood sugar is higher than normal but not high enough to be classified as diabetes. This is an opportunity to make lifestyle changes to prevent the progression to type 2 diabetes.
  • Diabetes (6.5% or above): An HbA1c level of 6.5% or higher on two separate tests indicates diabetes. Your doctor will work with you to develop a management plan to control your blood sugar and prevent complications.

It's important to remember that HbA1c test results can be affected by factors like anaemia, recent blood loss or transfusions, and certain medications. Always discuss your results with your doctor to get personalised advice and guidance.

How to Manage Blood Sugar Levels with the Help of the HbA1c Test?

Here are some strategies for using your test results to keep your blood sugar in check:

  • Set personal HbA1c goals: Work with your doctor to establish a target HbA1c range based on your age, overall health, and other factors. For most people with diabetes, the goal is an HbA1c below 7%.
  • Make healthy lifestyle changes: Adopting a balanced diet, getting regular exercise, and maintaining a healthy weight can all help lower your HbA1c levels.
  • Take medications as prescribed: If lifestyle changes alone aren't enough to manage your blood sugar, your doctor may prescribe medications like metformin or insulin.
  • Monitor your progress: Regular HbA1c tests can show you how your efforts are paying off and motivate you to stay on track.

Frequently Asked Questions

  • Glycated haemoglobin test is done to To measure average blood sugar levels over 2-3 months, helping to detect diabetes or monitor its progress.
  • Diagnose prediabetes or diabetes in patients. Prediabetes indicates the risk of developing diabetes. 
  • In cases of known diabetics, HbA1c is used to monitor the condition. 
  • To identify if a patient is at risk of developing diabetes-related complications such as heart disease, stroke, and kidney disease.
  • To enable better management of diabetes through evaluation of treatment progress and optimisation.

The HbA1C- Glycated Haemoglobin test measures the amount of glucose attached to haemoglobin molecules in red blood cells over the last two to three months.

During the glycated haemoglobin test blood sample is taken from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. This usually takes less than five minutes.

HbA1c results are given in percentages.  

  • Normal: HbA1c below 5.7%
  • Prediabetes: HbA1c between 5.7% and 6.4%
  • Diabetes: HbA1c of 6.5% or higher

High HbA1C levels are seen in prediabetes and diabetes.

In a patient with pre-existing diabetes, HbA1c shows the effectiveness of treatment and diet control. HbA1c levels below 7% are considered excellent and above 8% are considered as unsatisfactory control.

There are no specific preparations required for the test. However, it is essential to follow your doctor’s instructions for preparing for the test. 

The following are some of the other tests that may be ordered with the HbA1c test:

  • Fasting Plasma Glucose Test: This measures the amount of glucose in the blood after an overnight fast.
  • Oral Glucose Tolerance Test: This test is similar to the glucose tolerance test. Instead of taking a baseline blood sample, the patient drinks a glucose solution, followed by a blood test two hours later.
  • Glycated Albumin Test: This test measures the albumin in the patient's blood that has become glycated.
  • A1C test
  • Glycated Hemoglobin test
  • Glycosylated Hemoglobin Test
  • Glycohaemoglobin test
  • Haemoglobin A1C test
  • HbA1C test

The component of red blood cells called haemoglobin transports oxygen to the cells of the body. Haemoglobin has been glycosylated when glucose, a form of sugar, in the blood naturally binds to haemoglobin molecules (also referred to as haemoglobin A1c, or HbA1c).

A person's haemoglobin becomes more glycosylated as their blood sugar level rises. For the duration of the red blood cell or roughly two to three months, the glucose is bound to the haemoglobin.

The following individuals should take an HbA1C- Glycated Haemoglobin test:

  1. People with Type 1 diabetes: People with type 1 should get tested for HbA1c test at least three or four times a year or as per the doctor's recommendation.
  2. People with Type 2 diabetes: People with type 2 diabetes should have an HbA1c test at least twice a year or as per the doctor's recommendation.
  3. People at risk for diabetes: People with prediabetes or who are at risk for developing type 2 diabetes should take an HbA1c test. This can help in assessing the risk and making lifestyle changes to prevent diabetes if necessary.
  4. People with unexplained symptoms: People with the following symptoms of diabetes should be tested for the HbA1c test:
  • Excessive thirst or hunger.
  • Frequent urination (pee) at night.
  • Weight loss without trying.
  • Blurry vision.
  • Tingling or numb hands or feet.
  • Extreme fatigue and dry skin.
  • Slow healing sores.
  • Sickness more frequently than normal.

This test may not be suitable in case of abnormal haemoglobin (hemoglobinopathy) and in haemolytic anaemia. In case your HbA1c is not reported due to haemoglobin disorders then a fructosamine test is advised.
