What Do The Results Of An A1c Test Mean

The results are given in percentages.

  • If your healthcare provider is trying to diagnose diabetes:
  • An A1c of 5.6% or lower means you do not have diabetes.
  • An A1c of 5.7% to 6.4% means you are at risk for diabetes. This is also called prediabetes.
  • An A1c of 6.5% or higher means you have diabetes.
  • If you currently have diabetes, your A1c goal may be 8% or lower. Your healthcare provider will decide what your goal should be. This decision is based on your diabetes history and other medical conditions. You may need an A1c test 2 to 4 times each year, depending on your blood sugar level control.

    How Often Do You Need The Test

    Your doctor probably will have you take the A1c test as soon as youâre diagnosed with diabetes. Youâll also have the test if your doctor thinks you may get diabetes. The test will set a baseline level so you can see how well youâre controlling your blood sugar.

    How often youâll need the test after that depends on several things, like:

    • The type of diabetes you have
    • Your blood sugar control
    • Your treatment plan

    Youâll probably get tested once a year if you have prediabetes, which means you have a strong chance of developing diabetes.

    You may get tested twice each year if you have type 2 diabetes, you don’t use insulin, and your blood sugar level is usually in your target range.

    You could get it three or four times each year if you have type 1 diabetes.

    You may also need the test more often if your diabetes plan changes or if you start a new medicine.

    Itâs not a fasting test. You can take it any time of day, before or after eating.

    People with diseases affecting hemoglobin, such as anemia, may get misleading results with this test. Other things that can affect the results of the hemoglobin A1c include supplements, such as vitamins C and E, and high cholesterol levels. Kidney disease and liver disease may also affect the test.

    What Does The Test Measure

    A1C blood sugar test with glucose level measurement list outline ...

    The hemoglobin A1c test measures the percentage of hemoglobin A in your blood that has glucose attached.

    The more glucose there is in the blood, the more of it will be bound to hemoglobin. Since red blood cells live about three months, your hemoglobin A1c test result corresponds to your average blood glucose level throughout the three months before your test.

    Why Would I Need This Test

    The test for HbA1c is used to diagnose and monitor diabetes.

    For people who have diabetes, the test is used to indicate how well the diabetes has been controlled over the last few months. People with diabetes are advised to have this test every 3 to 6 months, or more frequently if it is not under control.

    This is important. The higher the HbA1c, the greater the risk of developing complications such as problems with your eyes and kidneys.

    What If My A1c Is Too High

    If your A1C is high, you can bring it down again.

    If your A1C falls in the prediabetes range , you are in the perfect position to modify your lifestyle to lower your A1C and send diabetes packing. This can be done by being mindful of your nutrition and physical activity.

    If your A1C falls in the diabetes range , you can still lower your A1C with lifestyle changes, but your provider may prescribe some medications as well.

    How Does The Hemoglobin A1c Test Work

    The hemoglobin A1C is a test that measures your average blood sugar for the past three months. This test goes by other names, including glycated hemoglobin, glycosylated hemoglobin, or HbA1c.

    If you have diabetes, your doctor may use the A1C to check how well you are controlling your blood sugar. A high hemoglobin A1C may mean that your treatment plan needs revision. The A1C is also used to diagnose diabetes or prediabetes.

    Hemoglobin is the protein that gives red blood cells their color. Its job is to carry oxygen to all the cells in your body. As red blood cells travel around the body, glucose in the bloodstream attaches itself to the hemoglobin. The A1C test measures how much glucose is attached. Since red blood cells live around three months, the A1C test shows how high your blood sugar has been for the past three months.

    What Does Hba1c Mean

    HbA1c is whats known as glycated haemoglobin. This is something thats made when the glucose in your body sticks to your red blood cells. Your body cant use the sugar properly, so more of it sticks to your blood cells and builds up in your blood. Red blood cells are active for around 2-3 months, which is why the reading is taken quarterly.

    A high HbA1c means you have too much sugar in your blood. This means youre more likely to develop diabetes complications, like serious problems with your eyes and feet.

    Knowing your HbA1c level and what you can do to lower it will help you reduce your risk of devastating complications. This means getting your HbA1c checked regularly. Its a vital check and part of your annual review. Youre entitled to get this test at least once a year. But if your HbA1c is high or needs a little more attention, itll be done every three to six months. It’s really important not to skip these tests, so if you haven’t had one in over a year contact your healthcare team.

    Once you know your HbA1c level, its important that you understand what the results mean and how to stop them from getting too high. Even a slightly raised HbA1c level makes you more at risk of serious complications, so get all the facts here and be in the know about HbA1c.

    What Does The A1c Test Diagnose

    In a clinical context in which a healthcare provider considers oneâs medical history, symptoms, and risk factors, an A1c test can be a helpful tool for diagnosing prediabetes, type 1 diabetes, and type 2 diabetes. If you already have a diabetes diagnosis, the hemoglobin A1c test can help with monitoring your average blood sugar level and tracking your progress towards improved glycemic control.

    While the HbA1c test is valuable in the diagnosis of some forms of diabetes, it canât diagnose the following types of diabetes:

    • Gestational diabetes
    • Childhood diabetes

    Additionally, itâs important to know that the A1c test is not a replacement for regular blood glucose monitoring in diabetic patients.

    For Monitoring Diabetes Control

    Experts disagree somewhat on what the A1C target should be. The ADA recommends a general A1C target of less than 7% without significant hypoglycemia , while the American Association of Clinical Endocrinologists recommends a general target level of 6.5% or below.

    The ADA’s Standards of Medical Care in Diabetes for 2022 note the following A1C targets:

    A1C Targets for Diabetes Management
    Most non-pregnant adults without significant hypoglycemia < 7%
    Adults in which blood sugar can be managed safely without significant hypoglycemia or other adverse effects of treatment Target may be set lower than < 7%
    Adults with limited life expectancy or when the harms of treatment outweigh the benefits < 8%

    While helpful, these targets are general guidelines. Both the ADA and the AACE emphasize that A1C goals should be individualized based on factors such as:

    • Length of time you’ve had diabetes
    • How well you comply with your treatment plan
    • Your risk of developing complications from hypoglycemia

    For example, if you have a reduced life expectancy you’ve had diabetes for a long time and difficulty attaining a lower A1C goal you have severe hypoglycemia or you have advanced diabetes complications such as chronic kidney disease, nerve problems, or cardiovascular disease, your A1C target goal might be higher than 7%, but typically no higher than 8%.

    Heart Disease And Stroke

    A1c Levels Chart For Type 1 Diabetes

    People with diabetes are at an increased risk of heart disease. Chronic high blood sugar levels can damage nerves and blood vessels that control the heart.

    Diabetics also tend to develop heart disease younger than those without diabetes. The longer you have diabetes, the more likely it is you also have heart disease.

    Coronary artery disease is the most common type of heart disease. It is caused by the buildup of plaque in the walls of the coronary arteriesâthe blood vessels that supply blood and oxygen to the heart.

    Plaqueâcholesterol, fat, and cellular wasteâbuilds up in a process known as atherosclerosis. This decreases blood flow to the heart, which can cause a heart attack.

    Decreased blood flow to the brain can also cause a stroke. Diabetes is linked to an increased risk of stroke and higher rates of mortality from stroke.

    Diabetes also increases your risk of other heart disease risk factors. These include:

    Diabetic eye diseases can largely be prevented by managing your blood sugar levels. Over time, high blood glucose levels damage the tiny blood vessels in the back of your eyes.

    Damaged blood vessels may leak fluid and cause swelling. New blood vessels that form may be weak. These blood vessels can bleed into the middle part of the eye, cause scarring, or dangerously increase pressure inside your eye.

    Diabetic eye changes are often without symptoms at first. Eye damage can begin during the prediabetes stage and typically progresses slowly.

    Hemoglobin A1c With Eag Blood Test

    A Hemoglobin A1C test is a common blood test used to help evaluate a person’s risk for developing diabetes. Hemoglobin is a protein found in red blood cells that helps to carry oxygen from the lungs to other parts of the body. Hemoglobin molecules become glycated when they bind with excess glucose in the blood. A Hemoglobin A1C test measures the percentage of hemoglobin that is glycated. Since red blood cells typically live about 3 months, an A1C test can determine if your blood sugar levels have been elevated within the last few months. Elevated A1C can indicate that a person is at risk of becoming diabetic. If levels are high enough, it may mean that a person has already developed diabetes.

    In addition to measuring hemoglobin A1C levels, this test includes a calculation for estimated average glucose . EAG indicates a person’s average daily blood sugar level. EAG is reported in the same units that are typically used by a blood glucose monitor. An A1C can be more useful than a standard blood glucose test at monitoring risk for diabetes. The use of the Hemoglobin A1C with eAG test is endorsed by the American Diabetes Association.

    Turnaround time for the Hemoglobin A1C test is typically 1 business day.

    A1c Levels In People With Diabetes

    For people with diabetes, an A1C under 7% is typically considered good control. Research shows an A1C above 9% significantly increases the risk of diabetic complications. For adults with diabetes, the target A1C range is typically between 7% and 8%. This depends on your age and other health factors.

    A1C levels correspond to the following average blood sugar levels:

    A1C Level
    240 mg/dL

    What Do The Hgb A1c Blood Test Results Mean

    Higher levels of A1C in the blood indicate a difficulty for the body to process sugars and control levels. It is possible for some to have a normal blood sugar result with an at-home testing machine, but have a high A1C result from the HGB A1C blood test.If the test results do come back as high, then this measurement will either be used as a baseline for treatment if a diabetes diagnosis has not been made before. If the HGB A1C blood test is being used to track treatments, then the results will be compared to the baseline to determine if progress against the disease is being made.

    Unlike the at-home testing which recommends a reading between 70-120, with a maximum of 140 about 2 hours after meals, the HGB A1C blood test results come back as a percentage measurement. For most labs that will conduct this blood test, here are the ranges that are looked at and what those results mean.

    Very high:8% or higher. If this measurement was placed on an at-home blood testing machine, the average reading every day would be 205. It is an indication that diabetes is not being controlled very well.

    High:6.1-7%. This test result indicates that diabetes control is under control and being managed appropriately. Although blood sugar levels are higher than normal, long-term health risks are reduced.

    How Accurate Is The A1c

    Your doctor can do an A1C test using a blood sample from a finger prick. Called a point-of-care test, this test can be processed quickly. Your doctor may instead choose to take a larger blood sample and send it to a lab for processing. The results of the lab test may be slightly more accurate.

    If you have recently had a blood transfusion, your A1C may not be accurate. Other health conditions can affect the red blood cells and result in inaccurate A1C results. These include:

    Screening for diabetes is also important. Those with an A1C greater than 6% are at high risk of developing diabetes in the next 5 years. Identifying them is critical. Research shows that two interventions can lower their chances of developing diabetes. Lifestyle changes can reduce their risk by 50%. Using the drug metformin can reduce it by 30%.
