Do You Need To Fast For A Hemoglobin A1c Blood Test?

Hba1c, Not Fasting Morning Blood Sugar

Hba1c, Not Fasting Morning Blood Sugar

Doctors used to use your fasting morning blood sugar level as a guide to managing diabetes. Now they depend far more on a test called Hemoglobin A1C, or HBA1C. Eating raises blood sugar levels. If your blood sugar rises too high, sugar sticks to the surface of cells where it cannot be removed. The sugar is converted to a poison called sorbitol that damages the cell to cause heart attacks, kidney damage, blindness and other nerve damage. Your fasting morning blood sugar level doesn't tell you if you are getting cell damage, but the Hemoglobin A1C test actually measures how much sugar sticks to cells. Once you start treatment, your doctor should check you once a month to measure your HBA1C. If it is high, you should change your diet and or your doctor should change your medication. When the HBA1C is normal, you are doing everything right. See my reports on Who is Pre-Diabetic? Treatment of Insulin Resistance Dietary Treatment of Diabetes HWM Breuer.

Diabetes: Your A1c Test

Diabetes: Your A1c Test

www.CardioSmart.org The hemoglobin A1c test is a simple blood test that checks howmuch sugar, or glucose, is stuck to your red blood cells. This test also is called the glycohemoglobin test or the A1c test. Most doctors think the A1c test is the best way to monitor your diabetes over the long term. What does your A1c result mean? Your test results tell you how well you have controlled your diabetes over the last 3 months. With this information, your doctor can adjust your medicine and diabetes treatment, if necessary. This test also gives you an idea of how likely you are to develop problems such as kidney failure, vision trouble, or numbness in your leg or foot. Keeping your A1c level in your target range can lower your chance for problems. The test result is usually given as a percentage. The American Diabetes Association (ADA) recommends that most non-pregnant adults with diabetes have an A1c level less than 7%. If your A1c level is higher than your target A1c level, the ADA recommends that your doctor look at making changes in your diabetes treatment. To lower your A1c level, your blood sugar needs to be lower. In some people with diabetes, having blood sugar that is too low may cause problems. Your doctor can help you decide the best and safest A1c level. How often should you have your A1c tested? If you have diabetes, your doctor may order a test every 3 to 6months, depending on your type of diabetes and how well you control it. Generally, A1c is checked 2 to 4 times a year. Talk with your doctor about how often you should expect to have this test. If your levels have been good for several tests, you may not need the test as often. Do you need to fast before your A1c test? You do not need to fast before this test. You can have this test at any time during the day, Continue reading >>

and results will not be available to you until several days after your test. So now, onto the variety of tests that may be conducted. Technically, you're not required to fast for an A1c test, but because it's often taken alongside other tests, you'll likely be fasting when you have it. Hemoglobin is a protein component of your red blood cells. Sugar (glucose) will attach itself to the A1c test measures how much glycation has occurred on your red blood cells, and therefore, provides a picture of around in your blood. Because red blood cells die every 3 months, the A1c test reflects the average blood sugar value over the last 3 months. When you receive your result for the hemoglobin A1c test (often shortened to A1c or HbA1c), it will be written as a percent (%). Use this chart below to better understand what the percent means. Though note:Depending where you live in the world, A1c may differ slightly. For instance, normal A1c in US is considered under 5.7%. In the UK and Australia it is under 6%. Therefore, the generally recognized normal A1c range is between 4-6%. resultscame back above 5.7% (US), or 6% (UK, Canada & Aus) you may be diagnosed with prediabetes. Whereas, if your results came back above 6.5%, you may be diagnosed with type 2 diabetes. so it's as close to normal as possible (4-6%). Though sometimes your healthcare team may set your goals slightly higher, for instance, 7%. Remember, A1c is an average value of your blood sugar readings over the past 3 months. Doctors will typically order this test anywhere from 1 to 4 times throughout the year. While technically you do not need to fast for the above mentioned A1c test, almost always your doctor will order a In order to get true results, you will need to consume your last meal at least 8 hours prior to when yo Continue reading >>

A1c Test

A1c Test

Print Overview The A1C test is a common blood test used to diagnose type 1 and type 2 diabetes and then to gauge how well you're managing your diabetes. The A1C test goes by many other names, including glycated hemoglobin, glycosylated hemoglobin, hemoglobin A1C and HbA1c. The A1C test result reflects your average blood sugar level for the past two to three months. Specifically, the A1C test measures what percentage of your hemoglobin — a protein in red blood cells that carries oxygen — is coated with sugar (glycated). The higher your A1C level, the poorer your blood sugar control and the higher your risk of diabetes complications. Why it's done An international committee of experts from the American Diabetes Association, the European Association for the Study of Diabetes and the International Diabetes Federation, recommend that the A1C test be the primary test used to diagnose prediabetes, type 1 diabetes and type 2 diabetes. After a diabetes diagnosis, the A1C test is used to monitor your diabetes treatment plan. Since the A1C test measures your average blood sugar level for the past two to three months instead of your blood sugar level at a specific point in time, it is a better reflection of how well your diabetes treatment plan is working overall. Your doctor will likely use the A1C test when you're first diagnosed with diabetes. This also helps establish a baseline A1C level. The test may then need to be repeated while you're learning to control your blood sugar. Later, how often you need the A1C test depends on the type of diabetes you have, your treatment plan and how well you're managing your blood sugar. For example, the A1C test may be recommended: Once every year if you have prediabetes, which indicates a high risk of developing diabetes Twice a year if Continue reading >>

Blood Test: Hemoglobin A1c

Blood Test: Hemoglobin A1c

en españolAnálisis de sangre: hemoglobina A1c A blood test is when a sample of blood is taken from the body to be tested in a lab. Doctors order blood tests to check things such as the levels of glucose, hemoglobin, or white blood cells. This can help them detect problems like a disease or medical condition. Sometimes, blood tests can help them see how well an organ (such as the liver or kidneys) is working. A hemoglobin A1c test measures how well controlled glucose levels have been for the last 3 months. Glucose is a type of sugar used by the body for energy. Glucose levels and hemoglobin A1c levels can be high if diabetes is not well controlled. When a child has diabetes, hemoglobin A1c levels are followed to see how well medicines are working. If a child with diabetes has a high hemoglobin A1c level, it may mean that medicines need to be adjusted. Sometimes a hemoglobin A1c test is done as part of a routine checkup to screen for problems. How Should We Prepare for a Hemoglobin A1c Test? Your child should be able to eat and drink normally unless also getting other tests that require fasting beforehand. Tell your doctor about any medicines your child takes because some drugs might affect the test results. Wearing a T-shirt or short-sleeved shirt for the test can make things easier for your child, and you also can bring along a toy or book as a distraction.  Most blood tests take a small amount of blood from a vein. To do that, a health professional will: put an elastic band (tourniquet) above the area to get the veins to swell with blood insert a needle into a vein (usually in the arm inside of the elbow or on the back of the hand) pull the blood sample into a vial or syringe take off the elastic band and remove the needle from the vein In babies, blood draws are s Continue reading >>

Hemoglobin A1c Test (hba1c, A1c, Hb1c)

Hemoglobin A1c Test (hba1c, A1c, Hb1c)

Hemoglobin A1c definition and facts Hemoglobin A1c is a protein on the surface of red blood cells that sugar molecules stick to, usually for the life of the red blood cell (about three months). The higher the level of glucose in the blood, the higher the level of hemoglobin A1c is detectable on red blood cells. Hemoglobin A1c levels correlate with average levels of glucose in the blood over an approximately three-month time period. Normal ranges for hemoglobin A1c in people without diabetes is about 4% to 5.9%. People with diabetes with poor glucose control have hemoglobin A1c levels above 7%. Hemoglobin A1c levels are routinely used to determine blood sugar control over time in people with diabetes. Decreasing hemoglobin A1c levels by 1% may decrease the risk of microvascular complications (for example, diabetic eye, nerve, or kidney disease) by 10%. Hemoglobin A1c levels should be checked, according to the American Diabetic Association, every six months in individuals with stable blood sugar control, and every three months if the person is trying to establish stable blood sugar control. Hemoglobin A1c has many other names such as glycohemoglobin, glycated hemoglobin, glycosylated hemoglobin, and HbA1c. To explain what hemoglobin A1c is, think in simple terms. Sugar sticks to things, and when it has been stuck to something for a long time it's harder to the get sugar (glucose) off. In the body, sugar sticks too, particularly to proteins. The red blood cells that circulate in the body live for about three months before they die. When sugar (glucose) sticks to these red blood cells by binding to hemoglobin A1c, it gives us an idea of how much glucose has been around in the blood for the preceding three months. Hemoglobin A1c is a minor component of hemoglobin to which gl Continue reading >>

A1c Blood Test Ok For Diabetes Diagnosis

A1c Blood Test Ok For Diabetes Diagnosis

Dec. 29, 2009 -- The American Diabetes Association (ADA) is recommending that a simple blood test currently used to assess whether diabetes is under control also be used to diagnose the disease. The blood test -- known as the A1C test -- has several important advantages over traditional blood glucose testing. Patients do not need to fast before the test is given, and it is far less likely to identify clinically irrelevant fluctuations in blood sugar because it measures average blood glucose levels over several months. The new guidelines do not call for replacing traditional screening with the A1C test. It is believed that around 6 million Americans have diabetes but don't know it, and another 57 million have prediabetes. The A1C test may help identify a large number of people in both of these groups, former ADA president for medicine and science John Buse, MD, PhD, tells WebMD. Buse, who is chief of endocrinology at the University of North Carolina, Chapel Hill, helped draft the new ADA diabetes care guidelines, which were made public today. "We now know that early diagnosis and treatment can have a huge impact on outcomes by preventing the complications commonly seen when diabetes is not well controlled," he says. "Our hope is that people with early or prediabetes who might otherwise not be tested would have the A1C test." The A1C test has been used since the late 1970s as a measure of how well diabetes is managed, but the ADA had not previously recommended it for diagnosing the disease. In part, this is because earlier versions of the test were not as accurate as current versions. The test measures the percentage of glycated hemoglobin, or A1C, in the blood and provides an assessment of blood sugar levels over the previous two to three months. Hemoglobin is a protein Continue reading >>

Everything You Need To Know About Fasting Before A Blood Test

Everything You Need To Know About Fasting Before A Blood Test

How do you prepare for a blood test? Some blood tests will require you to fast beforehand. In these cases, your doctor will instruct you not to eat or drink anything, except water, in the hours leading up to the test. Fasting before certain blood tests is important to help make sure that your test results are accurate. The vitamins, minerals, fats, carbohydrates, and proteins that make up all food and beverages can impact blood-level readings, clouding the results of your test. Not all blood tests will require you to fast beforehand. Blood tests that you will likely need to fast for include: renal function panel lipoprotein panel If your doctor has prescribed a new blood test for you, or doesn’t mention whether or not you should fast or for how long, ask them if fasting is required. Some tests, such as a fecal occult blood test, don’t require fasting but do limit certain foods. Red meats, broccoli, and even some medications may cause a false positive test. Always follow your doctor’s advice when preparing for a test. The amount of time you need to fast for will vary depending on the test. For most tests, you will be told not to consume anything but water for eight hours leading up to the test. For a few tests, a 12-hour fast may be needed. Schedule your test as early in the day as possible. The hours you spend sleeping are considered part of the fasting period, as long as you don’t break your fast with coffee or food once you’re awake. Even if you drink it black, coffee can interfere with blood test results. That’s because it contains caffeine and soluble plant matter, which might skew your test results. Coffee is also a diuretic, which means that it will increase how much you pee. This can have a dehydrating effect. The less hydrated you are, the harder it Continue reading >>

5 Simple Ways To Lower Your A1c This Week

5 Simple Ways To Lower Your A1c This Week

The A1C blood test is a simple test that analyzes your glucose (blood sugar) levels by measuring the amount of glycated hemoglobin in your blood. Hemoglobin is a protein in your red blood cells; when glucose enters the blood, it attaches to the hemoglobin. The result is glycated hemoglobin. The more glucose in your blood, the higher your glycated hemoglobin. The A1C is a valuable indicator of how well your diabetes management plan is working. While your individual A1C goal will depend on factors including your age and your personal medical profile, most people with diabetes aim to keep their A1C below 7 percent. By keeping your A1C number within your target range, you can reduce the risk of diabetes complications. While it is important to develop a long-term diabetes management plan with your physician, there are several steps you can take right away to help reduce your A1C. Small changes add up, so consider trying some of these strategies to lower your A1C this week. 1. Try Short Sessions of High Intensity Exercise According to research presented at the American Heart Association's Scientific Sessions 2015, type 2 diabetes patients who did 10 minutes of exercise three times a day, five days a week at 85 percent of their target heart rate had a twofold improvement in A1C levels compared to patients who exercised for 30 minutes a day at 65 percent of their target heart rate. Be sure to check with your doctor before trying high intensity exercise, and wear a heart rate monitor so you don’t overdo it. 2. Shrink Your Dinner Plate Instead of a large dinner plate for your meals, use a smaller salad plate. This simple swap can trick your eyes and brain into thinking you’re eating more than you really are, and you’ll feel satisfied with less food. It’s especially helpfu Continue reading >>

What Is The A1c Test? How Does A1c Relate To Blood Glucose?

What Is The A1c Test? How Does A1c Relate To Blood Glucose?

Anyone with diabetes will be familiar with finger-prick testing for monitoring blood glucose to see how well they are managing their disease. This kind of regular testing is essential for most people with diabetes, but what role does an occasional hemoglobin A1C blood test play in controlling blood sugars, and how does it work? Contents of this article: What is the A1C test? The abbreviation A1C is used in the US (sometimes with a lower-case 'c' - A1c) and is short for glycated hemoglobin (sometimes called 'glycosylated' hemoglobin or glycohemoglobin). The other abbreviations in use are: HbA1c (widely used internationally) HbA1c Hb1c HgbA1C. The A1C test is a blood test used to measure the average level of glucose in the blood over the last two to three months. This test is used to check how well blood sugar levels are being controlled in a person with diabetes and can also be used in the diagnosis of diabetes.1 Hemoglobin is the protein in red blood cells which is responsible for transporting oxygen around the body. When blood glucose levels are elevated, some of the glucose binds to hemoglobin and, as red blood cells typically have a lifespan of 120 days, A1C (glycated hemoglobin) is a useful test because it offers an indication of longer term blood glucose levels.2 The particular type of hemoglobin that glucose attaches to is hemoglobin A, and the combined result is call glycated hemoglobin. As blood glucose levels rise, more glycated hemoglobin forms, and it persists for the lifespan of red blood cells, about four months.2 Therefore, the A1C level directly correlates to the average blood glucose level over the previous 8-12 weeks; A1C is a reliable test that has been refined and standardized using clinical trial data.3 There are two key things to know about the appl Continue reading >>

All About The Hemoglobin A1c Test

All About The Hemoglobin A1c Test

People with diabetes used to depend only on urine tests or daily finger sticks to measure their blood sugars. These tests are accurate, but only in the moment. As an overall measurement of blood sugar control, they’re very limited. This is because blood sugar can vary wildly depending on the time of day, activity levels, and even hormone changes. Some people may have high blood sugars at 3 a.m. and be totally unaware of it. Once A1C tests became available in the 1980s, they became an important tool in controlling diabetes. A1C tests measure average blood glucose over the past two to three months. So even if you have a high fasting blood sugar, your overall blood sugars may be normal, or vice versa. A normal fasting blood sugar may not eliminate the possibility of type 2 diabetes. This is why A1C tests are now being used for diagnosis and screening of prediabetes. Because it doesn’t require fasting, the test can be given as part of an overall blood screening. The A1C test is also known as the hemoglobin A1C test or HbA1C test. Other alternate names include the glycosylated hemoglobin test, glycohemoglobin test, and glycated hemoglobin test. A1C measures the amount of hemoglobin in the blood that has glucose attached to it. Hemoglobin is a protein found inside red blood cells that carries oxygen to the body. Hemoglobin cells are constantly dying and regenerating, but they have a lifespan of approximately three months. Glucose attaches, or glycates, to hemoglobin, so the record of how much glucose is attached to your hemoglobin also lasts for about three months. If there’s too much glucose attached to the hemoglobin cells, you’ll have a high A1C. If the amount of glucose is normal, your A1C will be normal. The test is effective because of the lifespan of the hemogl Continue reading >>

Ultimate Guide To The A1c Test: Everything You Need To Know

Ultimate Guide To The A1c Test: Everything You Need To Know

The A1C is a blood test that gives us an estimated average of what your blood sugar has been over the past 2-3 months. The A1c goes by several different names, such aswa Hemoglobin A1C, HbA1C, Hb1C, A1C, glycated hemoglobin, glycohemoglobin and estimated glucose average. What is Hemoglobin? Hemoglobin is a protein in your blood cells that carries oxygen. When sugar is in the blood, and it hangs around for a while, it starts to attach to the red blood cells. The A1C test is a measurement of how many red blood cells have sugar attached. So, if your A1C result is 7%, that means that 7% of your red blood cells have sugar attached to them. What are the Symptoms of a High A1C Test Level? Sometimes there are NO symptoms! That is probably one of the scariest things about diabetes, your sugar can be high for a while and you may not even know it. When your blood sugar goes high and stays high for longer periods of time you may notice the following: tired, low energy, particularly after meals feel very thirsty you may be peeing more than normal, waking a lot in the middle of the night to go dry, itchy skin unexplained weight loss crave sugar, hungrier than normal blurred vision, may feel like you need new glasses tingling in feet or hands cuts or sores take a long time to heal or don’t heal well at all frequent infections (urinary tract, yeast infections, etc.) When your blood sugar is high, this means the energy that you are giving your body isn’t getting into the cells. Think about a car that has a gas leak. You put gas in, but if the gas can’t get to the engine, the car will not go. When you eat, some of the food is broken down into sugar and goes into your bloodstream. If your body can’t get the sugar to the cells, then your body can’t “go.” Some of the sugar tha Continue reading >>

Glycated Hemoglobin Test

Glycated Hemoglobin Test

The glycated hemoglobin test is also referred to as the “hemoglobin A1c test”. It is a measure of the amount of “sugar coating” is on the red blood cells as a result of diabetes mellitus. Because red blood cells live for about 3 months, the test is a good measure of the average blood sugar values over that previous three months. This is a test that is sometimes used to diagnose diabetes mellitus but is more commonly used to see how the blood sugar levels have been in patients already diagnosed with diabetes. The glycated hemoglobin test is based on the amount of sugar (glucose) attached to the hemoglobin inside of red blood cells. Hemoglobin is the protein within the red blood cells that transfer oxygen to the tissues from the lungs. As the red blood cells are being formed, hemoglobin is a part of the making of the cells. If the hemoglobin is exposed to high blood glucose levels during the making of a red blood cell, the end result is an elevated glycated hemoglobin test. A normal glycated hemoglobin level is anything less than 5.7. The glycated hemoglobin test can be used to diagnose prediabetes and type 2 diabetes. According to experts on diabetes, the hemoglobin A1c test (glycated hemoglobin test) can be used to diagnose type 1 or type 2 diabetes in a similar way that fasting blood sugar levels and glucose tolerance tests are used in order to see if an individual has diabetes. The test involves a simple blood draw that can be done when the person is fasting or non-fasting. The glycated hemoglobin test may, in fact, be the best test to diagnose diabetes because it can be drawn at any time during the day regardless of the fasting status of the individual. Rather than identifying the blood sugar at any given point in time, the glycated hemoglobin test can tell w Continue reading >>

A1c Test

A1c Test

Definition A1C is a lab test that shows the average level of blood sugar (glucose) over the previous 3 months. It shows how well you are controlling your diabetes. Alternative Names HbA1C test; Glycated hemoglobin test; Glycohemoglobin test; Hemoglobin A1C; Diabetes - A1C; Diabetic - A1C How the Test is Performed A blood sample is needed. Two methods are available: Blood drawn from a vein. This is done at a lab. Finger stick. This can be done in your health care provider's office. Or you may be prescribed a kit that you can use at home. How to Prepare for the Test No special preparation is needed. The food you have recently eaten does not affect the A1C test, so you do not need to fast to prepare for this blood test. How the Test will Feel With a finger stick, you may feel slight pain. With blood drawn from a vein, you may feel a slight pinch or some stinging when the needle is inserted. Afterward, there may be some throbbing or a slight bruise. This soon goes away. Why the Test is Performed Your provider may order this test if you have diabetes. It shows how well you are controlling your diabetes. The test may also be used to screen for diabetes. Ask your provider how often you should have your A1C level tested. Usually, testing every 3 or 6 months is recommended. Normal Results The following are the results when A1C is being used to diagnose diabetes: Normal (no diabetes): Less than 5.7% Pre-diabetes: 5.7% to 6.4% Diabetes: 6.5% or higher If you have diabetes, you and your provider will discuss the correct range for you. For many people, the goal is to keep the level below 7%. The test result may be incorrect in people with anemia, kidney disease, or certain blood disorders (thalassemia). Talk to your provider if you have any of these conditions. Certain medicines can Continue reading >>
