A1C test for Diabetes (HbA1c) – What is a Good A1C Test Result? SUGARMD

Now that you have an estimate of your A1C, check whether your levels are outside of the normal range by comparing your result to the ranges used by both the American Diabetes Association and the CDC:

If your estimated range falls anywhere above 5.7 percent, you may want to visit your doctor to learn more about the factors that can affect your blood sugar response. One way to detect imbalances and fluctuations in glucose to see its impact on overall wellness is by using a tool such as a continuous glucose monitor.

There are a number of lifestyle changes that may be beneficial as you work to lower your levels over time. Your doctor may also help you set an A1C goal to aim for.

How To Lower A1c Level

Your doctor will tell you to lower your A1C levels if your test shows they are too high. Here are a few pointers to get you started:

  • Consult your doctor about medicine. Make sure youre following the doctors instructions when taking them. Mention any other medications youre taking for different ailments, as they could interact.
  • Check your blood sugar levels more frequently and make sure youre using the suitable treatments . If you believe this is a problem for you, seek professional treatment.
  • Increase your physical activity. You dont have to train to be an Olympic athlete, but you should strive to include a few short walks in your daily routine. Every step is crucial!
  • Attempt to reach and maintain a healthy BMI .
  • The BMI is the most fundamental indicator, but you should also consider your waist-hip ratio. A large amount of visceral fat has been related to an increased risk of diabetes and heart disease.
  • Maintain a healthy, well-balanced diet. If youre overweight, dont go over your daily calorie restriction, and attempt to eat even less. Say goodbye to processed meals and sweets.

If you follow those recommendations, your hemoglobin A1C levels will almost certainly improve.

What Is An A1c Test

An A1c test measures your average blood sugar level over the past two to three months by determining what percentage of hemoglobin has glucose attached to it.

Hemoglobin is a protein molecule in red blood cells that transports oxygen throughout the body. Glucose sticks to this protein, and the more glucose you have in your blood over time, the more it will stick. Because red blood cells live for an average of two to three months, the A1c test is able to capture your average blood sugar over that period of time.

For people living with diabetes, this test is used to evaluate how well blood sugar is being managed. Your healthcare provider will determine what your target should be based on a variety of factors, including age, sex, diabetes type, and health history. They will also determine how often you should be tested.

A1c Tests Can Be Affected By Changes In Red Blood Cells Or Hemoglobin

Understanding A1c  T1D Toolkit

Conditions that change the life span of red blood cells, such as recent blood loss, sickle cell disease, erythropoietin treatment, hemodialysis, or transfusion, can change A1C levels.

A falsely high A1C result can occur in people who are very low in iron for example, those with iron-deficiency anemia. Other causes of false A1C results include kidney failure or liver disease.

If youre of African, Mediterranean, or Southeast Asian descent or have family members with sickle cell anemia or a thalassemia, an A1C test can be unreliable for diagnosing or monitoring diabetes and prediabetes. People in these groups may have a different type of hemoglobin, known as a hemoglobin variant, which can interfere with some A1C tests. Most people with a hemoglobin variant have no symptoms and may not know that they carry this type of hemoglobin. Health care professionals may suspect interferencea falsely high or low resultwhen your A1C and blood glucose test results dont match.

Not all A1C tests are unreliable for people with a hemoglobin variant. People with false results from one type of A1C test may need a different type of A1C test to measure their average blood glucose level. The NGSP provides information for health care professionals about which A1C tests are appropriate to use for specific hemoglobin variants.

How To Calculate A1c To Average Blood Sugar

  • There’s nothing more simple than using our A1c calculator. Just input the level of hemoglobin A1c from your laboratory test to get your result immediately. You can freely switch between units in both the hemoglobin and average blood sugar fields.

  • For those curious about the actual calculations, here is the A1c to average blood sugar formula:

    Average Blood Sugar = HbA1c * 28.7 – 46.7

  • If you want to convert hemoglobin A1c level from a percent to millimoles per moles , use the following equation:

    HbA1c = HbA1c * 10.93 – 23.5

  • To do the reverse calculation , use this formula:

    HbA1c = HbA1c * 0.09148 + 2.152

  • Risks Of Chronic High Blood Glucose Level

    You already know how to calculate A1c levels, but what should you do with the result? If your level is less than 5.7% – congratulations – this is a normal A1c level, and you have nothing to worry about. Maintain your healthy habits and keep your blood sugar level low.

    If you drifted into the prediabetes group – that’s a red flag. You’re at a high risk of diabetes, but there is still hope. Check out the How to lower A1c? section for some hints. Do not neglect this result, as chronic high blood sugar levels can lead to severe consequences, including:

    • Increased risk of cardiovascular diseases – myocardial infarction or brain stroke
    • Problems getting pregnant
    • Diabetic foot, potentially leading to amputation!

    If your A1c level is equal to or higher than 6.5%, you may be diagnosed as diabetic. If this is your result, book an appointment with your doctor immediately!

    Why Use An A1c Calculator

    Self-monitoring tools such as traditional blood glucose meters , continuous blood glucose monitors , and automatic blood glucose monitors report blood sugar in mg/dL or mmol/L, not a percentage. As a result, it can be difficult to understand the relationship between your daily blood sugar levels and your A1c results. An A1c calculator may give you a sense of how your average blood glucose matches up with the individual readings you take.

    What Are The Disadvantages Of Using A1c

    Like any other testing in medicine, that may be technical errors in interpreting A1c levels. These errors can lead to misleading results or assumptions. The lifespan of hemoglobin can influence the test results. The test result will be falsely high when the red blood cell turnover is lower. A1c levels will be falsely low when the red blood cell turnover is slow such as in untreated anemia. So, let us review possible problems with the the test.

  • False A1c test results tend to occur more in patients with iron deficiency anemia, vitamin B12 deficiency, and folate deficiency anemia.
  • Patients who have severe kidney disease taking erythropoietin will have a falsely low A1c result.
  • Depending upon the testing methodology, the values may be falsely high in patients with abnormal hemoglobins such as patients with sickle cell anemia or thalassemia.
  • Racial differences can also play a role in the ability of the test to estimate average blood sugars. For example, A1c levels are typically higher in African-American Hispanic in Asian populations compared to Caucasians. Thankfully racial differences do not lead to significant A1c problems as some other issues we discussed above.

    Using The Gmi To Estimate Your A1c: How Accurate Is It

    GMI provides an estimated A1C level based on continuous glucose monitoring data and can avoid some of the limitations of A1C tests. A recent study compared actual A1C levels with GMI to see how the two compared in the real world.

    The A1C test is commonly used to assess a persons glucose management. A higher A1C is associated with higher glucose levels and more health complications. Although long considered a gold standard in diabetes care, the A1C has a huge limitation: its just an average. A person could spend a lot of time with low blood sugar levels and a lot of time with high blood sugar levels, yet have an A1C under 7%, which is the target for most people with diabetes. You can learn more about the limitations of A1C here.

    For those who wear a continuous glucose monitoring system , the glucose management indicator essentially estimates A1C in fact, it used to be called an estimated A1C. Without the need for a blood draw, it takes the average of your glucose readings and uses a formula to estimate what your A1C is expected to be. To calculate GMI you should have at least 14 days of data.

    Your glucose management can also be measured by Time in Range , Time Below Range and Time Above Range . Generally, a Time in Range of 70% or greater is equivalent to an A1C of 7% or less. This data is quite useful to see if you are meeting your glucose targets or if you need to adjust your diabetes treatment plan. Learn about TIR and how it can help your diabetes management here.

    An International Expert Committee with members appointed by the American Diabetes Association, the European Association for the Study of Diabetes, and the International Diabetes Federation was convened in 2008 to consider the current and future means of diagnosing diabetes in nonpregnant individuals.2 The group concluded that the A1C assay provides a reliable measure of chronic glycemia and correlates well with the risk of long-term diabetes complications. The same year an international multicenter study by the ADAG Study Group reported the relationship between average glucose and A1C levels to estimate the relationship between the two metrics.3 This group derived a mathematical relationship using a combination of continuous glucose monitoring and frequent fingerstick capillary blood glucose testing.

    Drawbacks Of Using An Online A1c Calculator

    An A1c calculator can help people living with diabetes understand the connection between daily readings and longer-term results. However, such calculators are imperfect and have significant drawbacks.

    Online A1c calculators can provide only rough estimations, and sometimes not even that. Thats because A1c tests and daily glucose monitoring are looking at different parameters. While A1c tests assess average blood sugar over time, self-monitoring tools measure blood glucose in the moment and can detect sudden, short-term changes and low blood glucose events. That means your latest BGM reading may not reflect your long-term average blood sugar levels. Additionally, A1c test results can be affected by a number of health conditions, medications, blood loss, pregnancy, and conditions that affect your hemoglobin.

    Its important to remember that an A1c calculator cannot replace an A1c test or daily glucose monitoring, and it should not be used to make treatment decisions.

    The Most Accurate Method To Test Blood Sugar is NOT A1C Test â Dr. Berg

    Managing diabetes includes actively measuring and monitoring glucose levels. It involves collecting a lot of numbers. But none of these numbers truly tells the whole diabetes story.

    In the past, diabetes care focused primarily on A1C as a measure of good diabetes management. And sometimes having good numbers was equated with being good in your life with diabetes.

    But this singular focus also created some negative impacts. People who couldnt reach or keep up the ideal A1C level were often judged and stigmatized. They were labeled bad or noncompliant despite their best efforts.

    As a result, some became too closely identified with their numbers. They felt good about themselves and their diabetes management only if they had good numbers. Faced with the impossible task of perfect glucose management, some became discouraged and lost motivation to actively manage their diabetes.

    The American Diabetes Association s current Standards of Care call for individualized targets that take into account the persons stage of life, health history, social determinants of health, and personal health goals.

    This more modern approach recognizes and validates what people living with diabetes realized long ago: Our numbers dont tell the whole story when it comes to how well were managing our diabetes.
