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 >>
Hemoglobin A1c Test (hba1c Test)
The hemoglobin A1C test, also known as the HbA1c test, glycated hemoglobin test, or glycohemoglobin, is a blood test typically used to diagnose diabetes or evaluate diabetes treatment. This test measures the glucose in your blood over the last 2-3 months. Hemoglobin is found in red blood cells and helps to carry oxygen throughout the body. When blood sugar is too high, sugar builds up in the blood and combines with hemoglobin becoming glycated. The hemoglobin A1C test (hbA1c test) measures the average level of glucose in the blood. The results of this test can determine if a person has diabetes or how well a person with diabetes is controlling their blood sugar.

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 >>
How To Lower Your A1c For Diabetes Control
Do you know what the AIC test measures? Learn about this blood test and get tips to help lower A1C and manage diabetes over time. The A1C test is an essential part of living well with type 2 diabetes: This simple blood test to measure hemoglobin A1C, or HbA1C, provides information about your blood sugar control over the previous few months. The results are like a grade for how well you've been managing diabetes. By making the most of your daily efforts, you can lower your A1C results and take pride in all of your hard work. A1C 101 Unlike blood glucose monitoring, which you do at home yourself at frequent intervals, A1C levels are measured periodically by your doctor or a nurse in a medical office. During this test, a health care worker will use a needle to draw a blood sample from a vein in your arm, or by pricking the tip of your finger with a small lancet. The sample is then sent to a medical laboratory for analysis. The A1C test lets your doctor know about your average level of blood sugar control for the past three months. It looks at the way glucose has attached to hemoglobin, a component of red blood cells. Red blood cells live for about three months, which is how the A1C test can provide this overview. The results of the test are given as a percentage. Normal A1C is below 5.7 percent, and the results of the test are accurate within 0.5 percent. In general, the goal of blood sugar control is a result below a 7 percent A1C because the risk for diabetes complications is lower below that point. But that number isn't realistic for everyone with diabetes, so your doctor might recommend a different target for you. Understanding Blood Sugar Control “I explain that a blood sugar test gives a snapshot, and A1C is the whole motion picture,” says Joyce Malaskovitz, RN, Continue reading >>

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 >>
How To Prepare For A Blood Glucose Test
Are you prepared for your Blood Glucose Test? Yes, I know blood glucose test isn’t a war for which you need to prepare, rather blood glucose tests are very simple and easy process to diagnose your diabetic condition. But to get accurate conclusive results there are some points that can really affect your tests. So, whenever you go to the hospital for a blood glucose test or take test yourself, it is very important that you know and understand the method, precautions necessary for the tests such as: 1) If you are going for a random glucose test, you may eat and drink normally as you do but don’t overdo on high sugary drink. 2) If you will be taking a fasting blood glucose test, you must not eat or drink anything other than water for eight hours before the test. It is much better if you can schedule your fasting glucose test early in the morning so you can have overnight fasting and will not have to fast during the day. 3) It is very important that before the test or when scheduling for it, you tell your doctor about any other health condition and medications you are taking, including prescriptions, over the counter drugs and even any other herbal supplements. Some medications can affect blood glucose level and give false readings on the test. So, your doctor can take this into consideration and tell you to stop taking any particular medication or change the dosage before your test temporarily to minimize the effect on the test. Medications that can affect your blood glucose levels and the test include: Steroids Birth control pills Aspirin Epinephrine Acetaminophen Phenytoin Corticosteroids Atypical antipsychotics Tricyclic antidepressants Lithium Diuretics Monoamine Oxidase Inhibitors (MAOIs) Sulfonylurea medications Hormone therapy High stress is another reason for Continue reading >>
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 >>
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 >>
Tips For Maintaining A Healthy A1c Level | Revere Health
posted by The Live Better Team | January 15, 2018 An A1c test helps doctors see the amount of glucose in a persons blood (blood sugar) over a three-month period. When glucose builds up in your blood, it binds to a protein called hemoglobinthis molecule is responsible for the red color of your blood and carrying oxygen throughout your body. A1c tests measure what percentage of hemoglobin is coated by glucose. The higher your percentage, the higher your risk of diabetes and diabetes complications. Doctors use A1c tests to diagnose type 1 and type 2 diabetes and monitor patients who are already diagnosed with diabetes. If you have diabetes, you should get an A1c test regularly to evaluate how well you are managing your blood sugar. The normal A1c range for a non-diabetic person of average health is below 5.7 percent, according to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK). If your levels are between 5.7 to 6.4 percent, you may be prediabetic. A level of 6.5 percent or higher indicates diabetes. Patients with diabetes should aim for an A1c level below 7 percent. It may seem like a lofty goal, especially if your levels are high, but its important to remember that lowering your A1c levels reduces your risk of developing diabetes complications like kidney and nerve damage, cardiovascular disease, cataracts, etc. If you are at risk for diabetes or prediabetes and have not been diagnosed, an A1c test can help you determine whether you have the condition or are likely to develop diabetes. Because prediabetes usually does not present any signs or symptoms, its important to identify your risk factors and notify your doctor. How often you get tested depends on your diagnosis and your treatment plan. Here are some general recommendations: If you are Continue reading >>

Preparing For Diabetes Labs And Other Tests
When people take insulin or diabetes pills to control blood sugar, it might take some extra planning before getting lab work and other tests done. Many tests, such as a blood test to measure cholesterol, require that a person stop eating, drinking, and taking medicine for a certain amount of time before the test. Tests can also be stressful for people. Stress can cause blood sugar levels to go up. When that happens, a person needs to test blood sugar levels more often and adjust medicine as needed. If you're worried about any tests that you have scheduled, even if the test isn't related to diabetes, talk to your doctor or other member of your health care team. Ask if you need to do anything special to prepare and whether the test might affect your blood sugar levels. Preparing for Tests Tests that require you to be at the medical facility for several hours Some tests require you to be at the medical facility for several hours. Even if you don't need to make any changes in what you eat or drink, tell the people in charge of the testing that you have diabetes. Ask if there are any special steps you need to take to make sure you can keep your blood sugar levels stable. A week or so before the test, make sure you know: What time you'll be having your test. How the test fits with your schedule for eating and taking your diabetes medicines. When your diabetes medicine is likely to reach its peak. If it's during the test, find out if you will be able to eat or drink something right before or right after the test to keep your blood sugar from dropping too low. On the day of your test: Take glucose tablets or a carbohydrate snack and your diabetes medicine with you to the test. Remind the people doing the test that you have diabetes. Tell them when you last ate and, if you take Continue reading >>

What Is The A1c Test?
The A1C (“A-one-C”) is a blood test that checks your average blood sugar over the past 3 months. This average is different from your day to day blood sugar. There are 3 reasons to check your A1C: · To diagnose prediabetes · To diagnose diabetes · To see how well you are controlling your blood sugar Sugar absorbed from your food goes into the bloodstream. The sugar sticks to the hemoglobin protein in red blood cells, forming hemoglobin A1C. The A1C stays in the blood for the life of the red blood cell, which is 90 to 120 days. This means that the amount of A1C in your blood reflects how high your blood sugar has been over the past 3 months. Another name for this test is hemoglobin A1C test. It is different from a regular blood sugar or blood glucose test. WHY IS THIS TEST DONE? A1C is an excellent way to check how well you are controlling your blood sugar over a 3-month period. A1C tests are important because: · They can check the accuracy of the blood sugar results you get at home. · They help predict your risk of diabetic complications. The higher the A1C percentage, the greater your risk of serious problems from diabetes, like eye, kidney, blood vessel, or nerve damage. If your A1C is high, your diabetes plan will need to be changed. HOW DO I PREPARE FOR THIS TEST? You don’t need to do anything to prepare for this test. One of the advantages of this test is that you do not have to fast before you take it. HOW IS THE TEST DONE? A small amount of blood is taken from a vein in your arm with a needle. The blood is collected in tubes and sent to a lab. Having this test will take just a few minutes of your time. At some pharmacies you may be able to buy a device that allows you to test A1C at home. You may find that the results of the home test are not the same a Continue reading >>
How To Prepare For A Diabetes Checkup? Tests Involved In Diabetic Checkup
Diabetes increases our risk of many serious health problems. There may be no warning signs of diabetes; millions of people may therefore be unaware that they have the disease. Blood tests can help you to diagnose diabetes. Which Tests are Done to Diagnose Diabetes Checkup? The following blood tests can be done as part of a diabetes checkup for diagnosing diabetes: an A1C test, also called the hemoglobin A1c , HbA1c , or glycohemoglobin test Not all of the above tests are recommended for diagnosing all types of diabetes. Another blood test, the random plasma glucose (RPG) test, is sometimes used to diagnose diabetes when symptoms are present during a regular health checkup. The A1C test is a blood test that reflects the average of a persons blood glucose levels over the past 3 months and does not show daily fluctuations. It measures the percentage of blood sugar attached to hemoglobin, the oxygen-carrying protein in red blood cells. The higher the blood sugar levels, the more will be the hemoglobin having sugar attached. The A1C test should be performed using a certified method to obtain standardized results. The A1C test does not require fasting and can be performed at any time of the day. The A1C test result is reported as a percentage. The higher the percentage, the higher a persons blood glucose levels have been. A normal A1C level is below 5.7 percent. People with an A1C below 5.7 percent may still be at risk for diabetes, depending on the presence of other characteristics that put them at risk. An A1C of 5.7 to 6.4 percent indicates prediabetes. People with an A1C above 6.0 percent should be considered at very high risk of developing diabetes. A level of 6.5 percent or above means a person has diabetes.
