Do I Have To Fast For An A1c Test

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 >>

5 Ways To Lower Your A1c

5 Ways To Lower Your A1c

For some, home blood sugar testing can be an important and useful tool for managing your blood sugar on a day-to-day basis. Still, it only provides a snapshot of what’s happening in the moment, not long-term information, says Gregory Dodell, MD, assistant clinical professor of medicine, endocrinology, diabetes, and bone disease at Mount Sinai Health System in New York City. For this reason, your doctor may occasionally administer a blood test that measures your average blood sugar level over the past two to three months. Called the A1C test, or the hemoglobin A1C test, this provides a more accurate picture of how well your type 2 diabetes management plan is working. Taking the A1C Test If your diabetes is well controlled and your blood sugar levels have remained stable, the American Diabetes Association recommends that you have the A1C test two times each year. This simple blood draw can be done in your doctor's office. Some doctors can use a point-of-care A1C test, where a finger stick can be done in the office, with results available in about 10 minutes. The A1C test results provide insight into how your treatment plan is working, and how it might be modified to better control the condition. Your doctor may want to run the test as often as every three months if your A1C is not within your target range. What the A1C Results Mean The A1C test measures the glucose (blood sugar) in your blood by assessing the amount of what’s called glycated hemoglobin. “Hemoglobin is a protein within red blood cells. As glucose enters the bloodstream, it binds to hemoglobin, or glycates. The more glucose that enters the bloodstream, the higher the amount of glycated hemoglobin,” Dr. Dodell says. An A1C level below 5.7 percent is considered normal. An A1C between 5.7 and 6.4 perce Continue reading >>

Fasting Before A Blood Test: What You Need To Know

Fasting Before A Blood Test: What You Need To Know

By Lana Burgess Fasting before a blood test is when people are asked not to eat or drink anything other than water before some blood tests. But which blood tests require fasting and how can people fast safely? Fasting is not always necessary before a blood test, but when it is, it is only for a short time. Even so, the idea of not eating or drinking, even for a small amount of time, can seem daunting. Understanding when and how to fast before a blood test can help to reduce unnecessary worry. This article explores the types of blood tests that require fasting, why fasting is needed, and how a person can do it safely. Contents of this article: When should you fast before a blood test? Whether someone needs to fast or not before a blood test depends on the type of blood test they are having. Some blood tests require fasting to be effective, while others do not. The types of blood test that require fasting are as follows: Fasting blood glucose test Diabetes is a condition that can lead to there being too much sugar in the blood. A fasting blood glucose test measures levels of sugar in the blood to see if they are healthy. It is important that a person has not had anything to eat or drink other than water for 8 to 10 hours before a fasting blood glucose test. Fasting helps ensure that the blood test records an accurate measure of fasting blood sugar levels. The results help a doctor to diagnose or rule out diabetes. Blood cholesterol tests Cholesterol is a fatty substance in the blood. High cholesterol can lead to an increased risk of certain health conditions. Blood cholesterol tests, also known as lipid profiles, assess the quantities of fats in the blood. The different fats tested for include: HDL cholesterol, also known as "good cholesterol" LDL cholesterol, also known Continue reading >>

What Is The A1c Test?

What Is The A1c Test?

The A1C ("A-one-C") is a blood test that checks your average blood sugar over the past 2 to 3 months. This average is different from your day to day 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? There are 3 reasons to check your A1C: To diagnose prediabetes To diagnose diabetes To see how well you are controlling your blood sugar 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. A high A1C percentage means that your average blood sugar has been high, and this increases your risk of serious problems, like eye, kidney, blood vessel, and nerve damage problems. 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 don’t have to fast before you take it. How is the test done? Having this test will take just a few minutes. A small amount of blood is taken with a prick of the finger or from a vein in your arm with a needle. 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 as results of tests done at your healthcare provider's office. Talk with your provider about whether it Continue reading >>

Why Hemoglobin A1c Is Not A Reliable Marker

Why Hemoglobin A1c Is Not A Reliable Marker

i was recently tested for Hemoglobin A1c because i presented to an endocrinologist with extremely low blood glucose on lab test and some scary symptoms, not the ordinary hypoglycemia symptoms. My A1c was 4.7 which registered as low (L) on the lab print out–it was only slightly low. Does a low score on this suggest a possibility of short-lived RBCs? Does it have any relationship with extremely low blood glucose? my result at the lab, fasting, was 32mg/dL. Not long after that i got a home glucometer and i get the same kind of results on that as the lab got, in the 20s and 30s first thing in the morning, every day. did not know i had hypoglycemia until i had that lab test, though i had had one episode where i woke up with ataxia, i fell while walking to the bathroom first thing in the morning, i got up and immediately fell again. I soon found that i had very impaired coordination. i did not know why and i was very worried. Eventually i wanted to have breakfast but had great difficulty holding the measuring cup under the faucet, to get some water to heat, to make instant oatmeal, i lacked the coordination to get the water into the cup. I persisted and did make the instant oatmeal (pour hot water onto flakes and it’s done), and i got my lap top and was eating the oatmeal and i suddenly was aware that the symptoms were going away. Previously i had been unable to type. While eating the small amount of oatmeal, i realized i could type. That was about a month before the lab test. Since it only happened that once, i put it out of my mind. About 5 days after the lab test, i had the second episode, worse than the first, i woke falling out of bed to the floor, couldn’t use my arm to break the fall, i didn’t have the coordination. i sat on the floor, i could not get up and wa Continue reading >>

Hemoglobin A1c Testing: An Introduction

Hemoglobin A1c Testing: An Introduction

SHARE RATE★★★★★ Hemoglobin A1C testing (A1C) is the test used to measure your average blood glucose level over an extended period of time (2 to 3 months). It is used along with other blood glucose measurements, including random blood sugar testing, fasting blood sugar testing, and oral glucose tolerance testing, that provide a snapshot of your blood glucose at one point in time, to help determine whether your blood sugar is under control. The strength of A1C testing is that it is able to give a larger picture of how blood glucose levels change over days, weeks, and even months. How does A1C testing work? Hemoglobin is an important component of blood (it contains iron and gives blood its red color), responsible for transporting oxygen throughout the body. It is contained within red blood cells that have a lifespan of about 120 days.1 For the purposes of detecting elevated glucose levels and getting a picture of they change over time, hemoglobin A1C is useful because blood glucose tends to attach to hemoglobin. Normally, about 6% of hemoglobin has glucose attached. This combination of hemoglobin and glucose is called glycated hemoglobin or glycohemoglobin. There are different forms of glycohemoglobin, including A1A, A1B, and A1C. Of these, A1C is the most common, making up about two-thirds of glycohemoglobin.1 Advantages of A1C testing over glucose testing in diabetes No need for fasting Cost-effective and standardized test Shows blood glucose levels over time Indicator of future complications Reflects the course of diabetes and need for different levels of treatment How is an A1C test done? The A1C test is a blood test that your healthcare provider will perform. Someone at your doctor’s office or the clinic where you are having the test done will take a sampl 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 >>

Can I Eat Before Blood Tests?

Can I Eat Before Blood Tests?

Blood tests are a common way for your doctor to monitor your health and nutritional status, check for the presence of health conditions and assess your risk for disease. While the level of most blood components will not change rapidly from consuming nutrients, some of the substances in your blood will be affected by eating or drinking in the hours prior to the test. Before having blood tests completed, be sure to check with your doctor so you know if you can eat or need to fast prior to the test. Video of the Day Because blood glucose and blood fats can be elevated for several hours after eating, fasting glucose, triglyceride or cholesterol are the most common tests that require fasting. Certain hormone measurements, such as testosterone and cortisol, may require an early morning blood sample but will not require fasting. Your doctor may even ask you to avoid alcohol, certain nutritional supplements or medications prior to a test, but as a rule you can take medications and supplements according to your usual schedule -- even when fasting. Blood Tests That Do Not Require Fasting Most blood tests do not require any special preparation. For example, you will not need to fast prior to a pregnancy blood test. Fasting is also not required for many routine tests of blood chemistry -- for example, tests that measure kidney, liver or thyroid function can be completed any time of the day. Even the test that measures a 2 to 3 month average blood glucose -- the A1c test -- does not require fasting. Additionally, some cholesterol measures can be accurately measured without fasting if your doctor prefers to order these instead of fasting tests. How to Fast If you are required to fast prior to your blood test, you should receive specific instructions. Most cholesterol and triglyceride Continue reading >>

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.

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 >>

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 >>

Your Good Health: Blood-sugar Tests Show It’s Time For Changes To Diet

Dear Dr. Roach: My A1c test on blood sugar is always higher (prediabetes) than my fasting glucose test (normal) on the same visit to the doctor. Which result should I believe? My latest test at a doctor’s office showed that my A1c is 6.2 per cent, and fasting glucose is 88 mg/dL. The A1c pretty much remained at 6.2 per cent level, while the fasting glucose varied between 81 and 88 in the past two years. The test is drawing a blood sample after a 12-hour overnight fast. I am not taking any diabetes medication. Previously, my A1c results were 5.9 per cent in August 2016 and 5.5 per cent in December 2016. K.H. Both the A1c test and the glucose tests are blood tests for diabetes. The blood glucose test is a snapshot of an instant in time, while the A1c is a measure of the average value over the past two or three months or so. The A1c looks at the amount of sugar molecules on the large hemoglobin protein of the blood. In general, the A1c is a better screening test for diabetes than a fasting glucose test, because fasting blood sugar is normal for a long time (potentially years) before one shows overt diabetes. In early Type 2 diabetes, the only time the blood sugar gets above normal is after eating (the blood sugar is supposed to go up a bit after eating, but in the early stages of diabetes, it goes higher than it should). The most sensitive test for Type 2 diabetes is a glucose tolerance test, where a fixed amount of sugar is given, and the blood is tested after two hours. An elevated level at two hours is prediabetes or diabetes. However, the A1c, which is affected by both fasting blood glucose levels and those after eating, is nearly as sensitive, and is much easier to do. Both the glucose tolerance test and the A1c usually will diagnose prediabetes and diabetes before Continue reading >>
