What is the HbA1c test?

HbA1c Test, which is also known as the Glycated Hemoglobin Test, Hemoglobin A1c Test, or A1C Blood Test, evaluates the amount of glucose bound to the hemoglobin in the red blood cells. Red blood cells survive for about 120 days; thus, this test reflects the average blood glucose level over the last 2 to 3 months.

The HbA1c Test is primarily used to diagnose prediabetes and diabetes and to evaluate the effectiveness of blood sugar management in patients with diabetes. A high HbA1c level may indicate poor glycemic control. It may help to identify the risks of neuropathy, retinopathy, kidney damage, and heart problems associated with diabetes.

Unlike fasting blood sugar tests, HbA1c does not require fasting and can be taken at any time. This test is advised for people who have diabetes or are at risk of having diabetes. Redcliffe Labs makes this test convenient for you by collecting samples at your home.

Why is the HbA1c test done?

The HbA1c test is used for the following purposes: 

1. It is part of regular health checkup tests and used for general screening. This helps to detect a family history of diabetes, a history of gestational diabetes in PCOS, factors associated with obesity and blood pressure, etc. It helps mitigate significant health risks. 
2. When you persist with symptoms like constant fatigue, unexplained weight loss, frequent urination, hunger, thirst, and infections. 
3. This test is used to monitor higher-risk groups of people. People who are prediabetic need it at least twice in one or two years. Those who have had diabetes longer need an assessment every three to six months for better analysis.

Hba1c Test Details In Brief:

What are the Symptoms That Call For HBA1C Test?

Here are some symptoms & risk factors that may indicate the need for HbA1C Test. Signs you should pay attention to are:

• Frequent Urination: The frequent urge to urinate throughout the day, disrupting your routine, is the first sign that your blood sugar levels are not balanced.
• Excessive Thirst: Another common symptom indicating diabetes or prediabetes is unexplained & constant thirst, even after drinking adequate water. Excessive thirst may be a sign of elevated blood sugar levels.
• Unexplained Weight Loss: If you are losing weight without even trying changes in your diet or routine, it could be a sign of uncontrollable blood sugar levels or diabetes. And an HbA1C Test is often used to confirm the cause of your symptom.
• Persistent Fatigue: Constant lethargy or weakness can also be key indicators that your blood sugar levels are not balanced, and preventive measures should be taken to manage them in time.
• Blurred Vision: High blood sugar can usually disrupt the eyes' lens, leading to changes in eyesight or causing blurred vision. It is a sign that you need to check your blood sugar levels.
• Slow Wound Healing: Diabetes or elevated blood sugar levels can interfere with the body’s ability to heal wounds. If you notice cuts or bruises taking forever to heal, it may indicate uncontrolled blood sugar levels.
• Reoccurring Infections: Elevated blood sugar levels or diabetes usually compromises the immune system, leading to frequent or recurring infections.
• Change In Appetite: Sudden or unusual increased hunger can be a symptom indicating diabetes or uncontrolled elevated blood sugar levels.

Any of the above symptoms, accompanied by other factors, contribute to the risk of prediabetes & diabetes, and therefore, getting tested in time is crucial to confirm the cause and act for better management of the condition.

Besides the above symptoms, healthcare practitioners often recommend the HbA1c Test to individuals at high risk of developing diabetes.

What Does an HbA1c Test Measure?

The HbA1c test measures the percentage of hemoglobin with glucose attached. The glucose attaches to hemoglobin, a protein that helps transport oxygen from the lungs to other parts of the body.

Red blood cells have a life of about 120 days, indicating that the test results reflect the average glucose level in your blood over the previous two to three months, not just the current level.

It is unlike other tests, such as the finger-prick test and a fasting blood sugar test, since it provides a broader picture of your long-term glucose control.

HbA1c is used to;

• Diagnose prediabetes
• Diagnose diabetes
• Management of diabetes
• Evaluation of the efficacy of treatment
• Evaluate the risks of developing complications of diabetes.

What are the Factors That Contributes To High Risk For Diabetes?

• Obesity: Being overweight is the foremost factor that doubles one’s risk of developing diabetes. Excess body fat usually leads to insulin resistance, where the body’s cells don't respond to insulin effectively. So, healthcare practitioner often recommends this test for people who are obese.
• Family History: If you have a family history of diabetes or prediabetes, this is another factor that increases one’s risk of being affected by the disease.
• Age: As you age, your risk for developing diabetes increases too. However, it depends on an individual’s dietary or lifestyle choices.
• Underlying Medical Condition: Individuals with underlying chronic illnesses, like PCOS, high blood pressure, or a history of gestational diabetes, are also at risk for developing diabetes.
• Sedentary Lifestyle: If you are leading an unhealthy or sedentary lifestyle, it could also be a sign that your blood sugar levels are elevated and should be measured & monitored in time.

It is vital to understand that having any of the risk factors doesn’t necessarily mean an individual will develop diabetes. Therefore, doctors often suggest timely testing to confirm your health status and initiate the treatment accordingly.

What Diseases Can an HbA1c Test Detect?

The HbA1c test is primarily used to detect diseases associated with elevated blood glucose levels. It can help diagnose:

• Prediabetes: If your HbA1c level is 5.7% to 6.4%, you might have prediabetes, which means that your blood glucose level is higher than usual, but you may still develop type 2 diabetes later.
• Type 2 Diabetes: An HbA1c level of 6.5% or more may mean that you have diabetes and need to seek professional assistance for diagnosis.
• Managing Diabetes: Test results will help monitor blood glucose levels in patients with diabetes.

Although the HbA1c test can help diagnose diabetes, it cannot diagnose type 1 or gestational diabetes on its own. Doctors may recommend additional tests for an accurate diagnosis.
