Measuring HbA1C levels, commonly known as glycated haemoglobin, is a crucial step in the process of measuring blood sugar levels (glucose). The HbA1C test provides important data on average blood sugar levels over two to three months. For medical professionals and people with diabetes, understanding HbA1C values is essential for the following reasons:
1. Long-term Glucose Control:
HbA1C reflects blood sugar levels over the past few months, giving a broader view of control compared to daily measurements. It helps healthcare professionals assess the effectiveness of diabetes management plans and make necessary adjustments.
2. Treatment Planning:
HbA1C levels guide personalized treatment plans. Depending on the results, medications, lifestyle changes, and diet recommendations can be tailored to achieve optimal glucose control.
3. Risk Assessment:
HbA1C levels help evaluate the risk of complications. Higher levels increase the likelihood of heart disease, kidney problems, nerve damage, and eye issues.
4. Patient Empowerment:
Understanding HbA1C empowers individuals to participate actively in their care. It motivates them to make lifestyle changes, adhere to medication regimens, and adopt healthy habits for improved overall health.
5. Goal Setting and Progress Tracking:
The test serves as a benchmark for setting glycemic targets and monitoring progress. Regular monitoring allows individuals to track their achievements, identify areas for improvement, and celebrate progress.
What is HbA1C?

You probably might have questions about the test and what it means. Firstly, you need to know that HbA1C is an acronym for Hemoglobin (Hemoglobin is a protein found in red blood cells that carries oxygen throughout the body) A1C (A1C refers to a specific subtype of haemoglobin that has become glycated, meaning it is bound to glucose in the bloodstream) and the HbA1C test measures the percentage of glycated haemoglobin in the blood and is used to assess long-term blood sugar control in individuals with diabetes.
We can simply say: that HbA1C, also known as glycated hemoglobin, is a valuable indicator used to assess long-term blood sugar control in individuals with diabetes. It provides healthcare professionals with crucial information about average glucose levels over approximately two to three months.
HbA1C is created when glucose in the blood binds to haemoglobin, a protein present in red blood cells that transports oxygen. This process is known as glycation. This process occurs regularly and is directly affected by the quantity of glucose in the blood. Because red blood cells have a lifetime of around 120 days, testing HbA1C provides information on blood sugar levels across that period, of 120 days.
HbA1C is expressed as a percentage, indicating the proportion of glycated haemoglobin to total haemoglobin in the blood. The normal range for those who do not have diabetes is usually less than 5.7%. The desired HbA1C level for patients with diabetes, on the other hand, may vary depending on factors such as age, overall health, and the existence of complications.

The measurement of HbA1C is standardized and reported in two units: percentage and mmol/mol. The percentage unit represents the proportion of glycated haemoglobin, while the mmol/mol unit represents the concentration of HbA1C in millimoles per mole of haemoglobin.
HbA1C Testing and Interpretation
You may ask, “How often should you undergo HbA1c testing as a diabetes patient?” The frequency of HbA1c testing may vary depending on the type of diabetes, treatment plan, and overall health status. Generally, it is advised to have your HbA1C levels checked every three to six months. This interval enables medical professionals to monitor changes in blood sugar control over time and, if necessary, modify treatment plans accordingly. However, depending on the circumstances, specific recommendations might be given.
For individuals with well-managed diabetes and stable blood sugar levels, testing every six months may be sufficient. Those who have difficulties obtaining their goal HbA1C levels or who have frequent blood sugar changes, on the other hand, may require more frequent testing, such as every three months. These regular tests allow healthcare experts to closely monitor their development and intervene at the appropriate moment to enhance diabetes control.
It is crucial to remember that the suggested frequency of HbA1C testing is only a guideline, and the actual frequency may vary depending on individual needs. Healthcare experts collaborate with diabetes patients to select the best testing schedule for optimal blood sugar control and general well-being.

This convenience may be especially useful for last-minute treatment plan modifications or urgent assessments.
You submit an order online with Synlab, we collect your sample from your house, and you review accurate results (correct and confidential results are available on your secure online Pathprovider account). You will be contacted as soon as your results are available) and you will have access to medical support if you have any questions or concerns.
Interpreting The HbA1c Test
Understanding the meaning behind HbA1C results is important to gain insights into your blood sugar control. HbA1C is reported as a percentage or in millimoles per mole (mmol/mol), indicating the amount of glucose-bound haemoglobin in the blood over a specific time frame.
Let’s break down the interpretation of HbA1C results:
- 1. Below 5.7% (39 mmol/mol): This is considered within the normal range for individuals without diabetes. It indicates good blood sugar control and a lower risk of developing diabetes.
- 2. 5.7% to 6.4% (39–46 mmol/mol): This falls into the prediabetes range, suggesting an increased risk of developing diabetes. Lifestyle modifications, such as adopting a healthy diet and increasing physical activity, can help prevent or delay the onset of diabetes.
- 6.5% (48 mmol/mol) or higher: indicates diabetes. The higher the HbA1C level, the poorer the blood sugar control. It’s crucial to work with healthcare professionals to develop a comprehensive diabetes management plan.

To interpret HbA1C results on a practical level, you can follow these steps:
- Understand the target range: Consult with your healthcare team to determine the target HbA1C range that’s suitable for you based on factors such as age, overall health, and diabetes complications.
- Compare your result to the target range: If your HbA1C falls within the target range, it suggests that your blood sugar is well controlled. If it exceeds the target range, it indicates the need for adjustments in treatment or lifestyle modifications.
- Discuss with your healthcare professional: Take your HbA1C results to your healthcare professional for a detailed discussion. They can provide personalized guidance on medication adjustments, dietary changes, physical activity recommendations, and other strategies to improve blood sugar control.
Remember, HbA1C is just one aspect of diabetes management. Regular self-monitoring of blood glucose levels using a glucometer is also essential to capture day-to-day fluctuations. By actively participating in your diabetes care and working closely with your healthcare team, you can make informed decisions to better manage your blood sugar levels and overall health.

The importance of personalized HbA1C
It is important to note that when it comes to effectively managing diabetes, the importance of personalized HbA1C objectives cannot be emphasized. While there is a general target range for HbA1C, it is critical to set personalized targets depending on age, overall health, and diabetes complications. Here’s why this personalized approach is critical:
- Age: Age has an impact on HbA1C objectives. Individuals over the age of 65 or those with significant health issues may need to set somewhat higher goals to prevent low blood sugar (hypoglycemia) and promote general well-being. Younger people may have more stringent goals to maintain long-term diabetes management and prevent complications.
- Overall health: Other illnesses, such as cardiovascular or renal disease, have an impact on blood sugar control. The target range may need to be adjusted. Taking an individual’s general health state and comorbidities into account aids in setting acceptable HbA1C objectives.
- Diabetes complications, such as nerve damage or eye and renal difficulties, necessitate different HbA1C targets. Tighter management may be required to limit the progression of complications. These aspects are taken into account by healthcare experts when setting appropriate objectives.
By tailoring HbA1C goals to each person’s circumstances, healthcare professionals strike a balance between blood sugar control and minimizing risks. This approach ensures personalized diabetes management, accounting for unique needs and circumstances.
Why is HbA1C Important?
Given all we’ve spoken about thus far, I suppose you can name three (3) or more reasons why this test is important right now. Even if you are unable to identify one, the following examples will help:
- Unlike daily self-monitoring, which offers a moment-in-time perspective of blood glucose management, HbA1C offers a long-term perspective. This aids medical practitioners in evaluating the overall management of diabetes and choosing the best course of therapy.
- Elevated HbA1C levels are closely linked to an increased risk of diabetes complications. When blood sugar remains consistently high, it can lead to damage in various organs and systems of the body. The risk of complications, such as cardiovascular disease, neuropathy (nerve damage), retinopathy (eye damage), and kidney disease, rises with poorly controlled HbA1C levels. More reason for you to take your HbA1c levels seriously.
- Heart disease and stroke are two cardiovascular disorders that are accelerated and exacerbated by high HbA1C levels. Blood arteries can be harmed by persistently high blood glucose levels, which raises the risk of heart attacks and other cardiovascular events.
- Elevated HbA1C levels have been linked to neuropathy, which develops as a result of nerve injury. This illness frequently affects the hands and feet and manifests as tingling, numbness, discomfort, and weakness. HbA1C should be well managed to avoid or postpone neuropathy’s emergence and lessen its negative effects on everyday living.
- Another issue linked to high HbA1C levels is retinopathy, which is damage to the blood vessels in the retina. If addressed, it may cause visual issues and perhaps blindness. To preserve eye health and lower the risk of retinopathy, maintaining ideal HbA1C management is essential.
The significance of this test is that it will help you avoid all of these diseases’ potential side effects because prevention is always preferable to treatment.
