Biomarker Spotlight: Hemoglobin A1c

Picture of Healthyr


When it comes to keeping tabs on our health, testing our biomarkers is a big deal. These are little biological signals that tell us how our body’s doing, whether everything’s normal, or if there’s something we need to address. This month we’re shining a light on one specific biomarker called Hemoglobin A1c (HbA1c). Basically, it shows us how healthy our blood sugar levels are and how well our treatments are working. By getting familiar with this little guy, we can all make smarter choices about our health.


Understanding HbA1c

Hemoglobin A1c (HbA1c) is a biomarker that measures the amount of sugar (glucose) attached to hemoglobin. Hemoglobin is an important protein that carries oxygen from your lungs to all parts of your body through your red blood cells. This binding occurs over a span of a few months, giving us a valuable measure of average blood sugar levels over time. When there’s too much sugar in your blood, it can cause damage to your blood vessels and organs over time, leading to health problems such as diabetes, heart disease, and stroke.

How is HbA1c Measured?

The test is simple and painless, requiring only a small blood sample from a vein in your arm or a quick finger prick at home. So, after you give a sample, it gets sent to a lab for testing to see how much HbA1c is in it. They usually give you the results as a percentage, which tells you how much glycated hemoglobin is there.

Interpreting HbA1c Results

Generally, a higher HbA1c percentage indicates poorer blood sugar control over the previous few months. It’s commonly used to assess long-term glucose management in individuals with diabetes. A lower HbA1c percentage is generally a good thing, showing that blood sugar levels have been under control. Working together with your doctor is really important when it comes to setting goals that match your specific needs. This is especially true since different factors can affect how the results of the HbA1c test are interpreted.


The Link Between HbA1c and Diabetes

When we eat food, our body breaks down carbohydrates into a type of sugar called glucose. This glucose then enters our bloodstream. Normally, our pancreas releases insulin to help move the glucose from our bloodstream into our cells, which keeps our blood sugar levels stable. However, for those with diabetes, this process doesn’t work as it should. Without enough insulin or insulin that doesn’t work properly, glucose stays in the bloodstream instead of being transported into the cells, which leads to high blood sugar levels.

Monitoring HbA1c to Manage Diabetes

Over time, high blood sugar can cause complications. That’s why it’s important for individuals with diabetes to monitor their blood sugar levels. Checking your HbA1c regularly can help you and your healthcare team figure out if your treatment plan is working as it should and make any tweaks needed to keep your diabetes under control. Keeping HbA1c within the target range significantly reduces the risk of complications such as nerve damage, kidney problems, and heart issues. Over time, tracking your HbA1c levels lets you spot any patterns, trends, or areas that need some extra attention. This is a serious tool that helps personalize your treatment goals, adjust your meds, and make changes to your lifestyle.
If you’re someone with diabetes, it’s important to keep a close eye on your HbA1c levels and take a proactive approach to managing your condition. This can be a really effective way to stay healthy and feel your best.

HbA1c Targets and Goals

Keep in mind that these targets can vary depending on individual circumstances, so it’s essential to work closely with your healthcare team to set personalized goals.
A healthy A1C level should be below 5.7%, which is considered normal. However, if your A1C level ranges between 5.7% and 6.4%, it indicates pre-diabetes, thereby increasing your risk of developing type 2 diabetes. A score of 6.5% or higher signifies diabetes and requires immediate medical attention. It is important to note that the higher your A1C level is within the pre-diabetes range, the greater the risk of developing type 2 diabetes. Therefore, it is critical to monitor and maintain a healthy A1C level.

How Often Do You Need to Test?

If you have diabetes, you’ll likely need to get the A1c test done every three months. But if everything is looking good and your condition is under control, you might be able to stretch out the time between tests. Still, it’s a good idea to get checked at least twice a year, according to standard recommendations. 


Wrap Up

Monitoring your biomarkers is just one part of the puzzle when it comes to maintaining your health. Eating a healthy diet, exercising regularly, and managing your stress levels are all essential components of a healthy lifestyle. In fact, when it comes to managing pre-diabetes and diabetes, lifestyle changes such as diet and exercise can be just as effective as medication in controlling blood sugar levels. Taking charge of your health and making these lifestyle changes can reduce your risk of developing serious health problems and improve your overall quality of life.
