Diagnostic Diabetes Blood Test (HbA1c)
Measure an average blood sugar levels over two to three months.
What is this test?
The HbA1c blood test (glycated haemoglobin) is a diagnostic blood test used to measure a person's average blood sugar levels over two to three months. Regular HbA1c testing is crucial for individuals with diabetes to help maintain optimal blood sugar control and minimise the risk of long-term complications. It could also be a diagnostic marker to check whether you may have diabetes.
It is important to note that diabetes can have no symptoms. Risk factors include lifestyle and family history, amongst other factors.

What is included in this test
HbA1c (Hemoglobin A1c) and Glucose are fundamental indicators for monitoring blood sugar regulation. These markers provide insights into an individual's long-term and short-term glucose levels aiding in the diagnosis and management of diabetes.
The benefits of this blood test
- Check whether you may have diabetes
- Monitor diabetes control
- Treatment, health insights and support
- Guidance to manage the symptoms
- Lifestyle advice
If you are showing symptoms of diabetes, such as increased thirst, frequent urination, unexplained weight loss, or extreme fatigue, an HbA1c blood test can help confirm a diagnosis. Elevated levels of HbA1c indicate high average blood sugar levels over the past two to three months, which may indicate diabetes.
An HbA1c test can evaluate individuals at risk of developing diabetes or those with prediabetes, a condition characterised by higher than normal blood sugar levels. It helps identify individuals who may benefit from lifestyle modifications and preventive measures to delay or prevent the onset of diabetes.
Monitoring Blood Sugar Control
For individuals already diagnosed with diabetes, regular HbA1c tests are essential to monitor blood sugar control over time. These tests provide an average of blood sugar levels over the past two to three months, giving insight into the effectiveness of diabetes management strategies, including medication, diet, and lifestyle changes.
HbA1c test is valuable in guiding treatment decisions. If blood sugar levels are consistently high or fluctuating, an elevated HbA1c level may prompt healthcare providers to adjust diabetes medications and insulin dosage or recommend changes to diet and exercise routines to improve blood sugar control.
High HbA1c levels indicate poor long-term blood sugar control, which increases the risk of developing complications associated with diabetes. Regular monitoring of HbA1c levels helps assess the risk of complications such as heart disease, kidney damage, nerve damage, and eye problems. It guides healthcare providers in implementing appropriate preventive measures and treatment strategies.
