A1C: What It Means for Managing Diabetes

The A1C may come around as a complex medical term, but it’s rather a simple blood test that gives insight into your blood sugar levels over time. It helps in confirming if you are prediabetic, tracking how well your diabetes plan is working or maybe just learning about your health. 

Getting your A1C tests done is just the beginning of managing your diabetes and overall health.

What is the A1C Test?

An A1C test is a blood test also known as HbA1C (Hb stands for hemoglobin). This test is performed to check the quarterly average blood sugar levels. Unlike many other blood tests that detect your current health, an A1C test provides a long-term report card for your blood sugar control. A1C test results are given in percentage, and the higher the percentage, the more likely you have or may have diabetes in the future.

Is A1C Test Important? Why?

An A1C test isn’t a necessity for all but it does hold a lot of importance. Doctors rely on this blood examination to diagnose prediabetes and Type 2 diabetes. The test is also useful in determining whether diabetes treatments are effective or if the care plan needs any changes.

How Does the A1C Test Works?

When sugar or glucose enters your bloodstream, it sticks to the hemoglobin through the process of Glycation. This process happens more often when blood sugar levels are high.

An A1C test measures the percentage of glycated hemoglobin and how blood sugar has been managed over time.

Understanding your A1C Results

A1C results are measured in percentage, and here’s a quick breakdown of different levels:

• Below 5.7%: Normal
• 5.7% to 6.4%: Prediabetes
• 6.5% or higher: Diabetes

For those with diabetes, a target A1C level of 6.5%-7% or lower is recommended by the doctor. Whereas for those who aren’t diabetic, an A1C level below 5.7 is ideal. However, doctors may suggest a different goal given your individualistic health.

Why Long Terms Testing Matters?

People concerned about their diabetic health often rely on daily finger-stick tests or the usual ‘Fasting/ Random’ blood sugar test. However, none of them are like A1C, which gives a broader view of how glucose has been managed over several weeks. A broader view matters for identifying trends and determining whether your current plan is working.

Can A1C Results Mislead? When?

Although the A1C test is a helpful tool, it’s not perfect, and it can mislead. There are a lot of factors that can influence the results, leading to inaccuracies and misleading. Here’s an overview of what may cause the misleading numbers:

Factors Responsible to Lower A1C Results-

Some health conditions can show lower levels with A1C results including a few like:

• Blood disorders like hemolytic anemia, sickle cell anemia, spherocytosis etc, can mislead A1C readings.
• Medical treatments like iron supplementation, erythropoietin-stimulating agent (ESAs), or blood transfusion impact the levels.
• Kidney or liver issues can impact the A1C accuracy as well.
• Factors like living at high altitudes, alcohol consumption, and pregnancy can show lower test results.

Factors Responsible to Increase A1C Results-

On the other hand, some conditions may show higher A1C results:

• Iron deficiency anemia, or the ones caused by infections or tumors, can show a false increase in A1C results.
• Vitamin deficiency, particularly low levels of Vitamin B12, can interfere with results.
• Medical conditions like hyper triglyceridemia levels or thalassemia generally show false high results.
• Medications like immunosuppressants or protease inhibitors also interact with the readings.

Putting A1C in Context

Since A1C can be misleading, relying on them alone isn’t always a smart idea. Instead, it is important to pair your A1C results with other tools for a more complete picture of blood sugar management.

Here are some additional medical examinations that may offer a complete understanding:

• Daily blood glucose monitoring at home can help identify patterns that A1C tests may not reveal.
• Continuous glucose monitoring (CGM) offers real-time data, thus helping to fill in gaps that A1C results might miss.
• A Fructosamine test may offer a shorter-term view compared to A1C, proving ideal for those with conditions that affect A1C accuracy.
• Self-monitoring of blood glucose (SMBG) through portable glucose meters is another way to stay informed.
• An oral glucose tolerance test (OGTT) is useful when A1C or fasting blood sugar results are inconclusive.
• Pairing A1C with other tools ensures a more accurate understanding minus misleading results for a well-rounded plan.

When to Question Your A1C Test Results?

You should ideally question your A1C results when either of:

• The level doesn’t match up with your daily glucose readings.
• Or, if you aren’t feeling well.

In any of the above conditions, it is worth having a conversation with your doctor.

Your Health Is More Than a Number

Ultimately, the A1C test is just another piece of the puzzle and not the entire picture. Although it is a powerful medical assessment for tracking long-term blood sugar levels, it alone isn’t the entire story. Working with your healthcare provider closely on a well-planned approach is a more meaningful step toward managing diabetes and overall health.
