How does a blood sugar test work?
The HbA1c test is a type of blood test that determines the average amount of blood glucose (sugar) over the previous three months. Glucose, a sugar circulating in the bloodstream, attaches itself to hemoglobin, a protein in red blood cells. The greater the amount of glucose in the blood, the higher the number of red blood cells with glucose-bound hemoglobin (HbA1c). Since red blood cells are regularly replaced in the body and live for about three months, this test provides a good indication of your average blood sugar levels during that period. The results of the test will show if your average blood sugar level for the past three months is within normal limits. A high HbA1c value could suggest the possibility of diabetes or prediabetes.
What is HbA1c?
HbA1c, short for ‘hemoglobin A1c’ or glycated hemoglobin, is a specific form of hemoglobin. Hemoglobin is a protein in red blood cells that gives them their red color and is essential for transporting oxygen from the lungs throughout the body. In addition to carrying oxygen, hemoglobin can also bind with glucose (sugar) in the blood, forming what is known as glycated hemoglobin. This means the more glucose present in the blood, the more glycated hemoglobin there will be. Since red blood cells—and thus the hemoglobin in them—have a lifespan of up to 120 days, the HbA1c measurement offers an average of your blood glucose levels over the past 10 to 12 weeks. A higher HbA1c value indicates that the glucose level in your blood has been elevated over the time leading up to the test.

What is diabetes?
Diabetes is a chronic condition characterized by elevated levels of blood sugar (glucose). This condition arises either due to the pancreas not producing enough insulin or the body not utilizing insulin effectively. If diabetes is not properly managed, it can lead to severe health issues, including kidney damage, nerve damage (neuropathy), vision loss, and an increased risk of heart and blood vessel diseases.
There are two types of diabetes: type 1 and type 2. Type 1 diabetes is an autoimmune disease where the body’s immune system attacks the cells in the pancreas that produce insulin. People with type 1 diabetes must regularly administer insulin to maintain their blood sugar levels. On the other hand, type 2 diabetes develops when the body either doesn’t produce sufficient insulin or doesn’t use it effectively. Type 2 diabetes often develops more slowly than type 1, which can make its early detection challenging. Management of type 2 diabetes typically involves lifestyle modifications, such as changes in diet, increased physical activity, and weight loss, but it may also require medication. In some cases, individuals with type 2 diabetes might need to take insulin as well.
What is prediabetes?
Prediabetes is a condition where blood sugar levels are elevated above normal but not enough to qualify as type 2 diabetes. This stage heightens the likelihood of progressing to type 2 diabetes and encountering other health issues like heart disease. A key indicator of prediabetes is an HbA1C level ranging from 6.0% to 6.5%, marking the phase preceding type 2 diabetes.
Without changes in daily habits, people with prediabetes are at risk of progressing to type 2 diabetes. At this stage, potential harm to vital organs like the heart, blood vessels, and kidneys due to diabetes might already have started. However, there is good news: implementing lifestyle changes such as regular physical activity and weight management, reversing prediabetes is possible.
How soon will I receive my test results?
Once you have collected your sample and then mailed it to our laboratory, it generally takes a few working days before you receive the test result. As soon as your test sample arrives at the laboratory you will receive a notification by email. Once your test result is ready, you will receive a text message and an email from us with a link to your test result. We will therefore keep you well informed throughout the entire testing process!
What does the result of this test mean?
The result of this test shows what your average glucose level has been over the past 3 months. If this value deviates from the target range, this may indicate pre-diabetes or diabetes. In this case, consult your doctor so that he or she can establish the diagnosis.
Which HbA1c value indicates diabetes?
- An HbA1c of less than 6.0% means that your blood sugar levels are normal and that you do not have diabetes, or your diabetes is under control.
- An HbA1c between 5.7% and 6.5% may mean that you have prediabetes, also known as impaired glucose intolerance. This is the preliminary stage of type 2 diabetes, and is a reversible condition. If your test results indicate prediabetes, contact your doctor discuss lifestyle changes that can be made to prevent the progression to type 2 diabetes.
- An HbA1c of 6.5% or higher means that you have type 1 or type 2 diabetes. Please contact your doctor for further testing.
Common symptoms of diabetes or pre-diabetes are:
- Thirst
- Frequent urination
- Weight loss or gain
- Fatigue
- Sugar cravings
- Irritated easily
- Nausea
- Blurred vision

Why is diabetes or an elevated HbA1c level harmful to health?
Most of the food we eat is converted into sugar (glucose) and enters our bloodstream. When the amount of sugar in the blood rises, the pancreas is prompted to release insulin, enabling cells to utilize this blood sugar for energy. In diabetes, there’s either a deficiency in insulin production or a decreased cellular response to insulin over time. As a result, excess sugar stays in the blood and circulates throughout the body. Elevated blood sugar can lead to significant health issues, including heart disease, nerve damage, and vision complications. This is why it is very important to monitor blood sugar levels and recognize diabetes or pre-diabetes.
Who is this test suitable for?
This test is suitable for anyone who may recognize the symptoms in the “symptoms” section and thinks they have diabetes or pre-diabetes. The test is also suitable if you have diabetes in your family and would like to monitor your blood sugar, or if you have previously been diagnosed with diabetes and would like to know how well you have your diabetes under control.
