Asknadia: What’s The Science Behind The A1c Test

Dear Nadia, What’s the science behind the A1C test ? My husband is a type 2 diabetic and recently received his A1C results which was 9 percent. What is considered a good A1C range? RAS Dear RAS, The A1C sometimes referred to as the Hemoglobin A1C, glycosylated hemoglobin, glycated Hemoglobin and HbA1C measures your husband’s average glucose from 60 to 90 days. When your husband tests his blood sugars with a blood glucose meter, this only tells him what his glucose level is at that moment in time. It does not accurately reflect the highs and lows he experiences nor does it reflect the direction his glucose could be trending. Blood cells form and die within a 90 day period. The A1C test records the memory in the red blood cells, giving us an average reading that correlates with a percentage. People that don’t have diabetes have an average A1C of 4 to 6%. A 9 percent A1C means your husband’s blood sugars are averaging around 212 milligrams per deciliter and millimoles per liter Sometimes you can get a false A1C high if you have anemia, an iron deficiency or a blood transfusion. The percentage can also vary depending on where you get your A1C tested. It’s best to use the same lab. The American Diabetes Association recommends taking your A1C test twice a year. Their target A1C is 7 percent. The American Association of Clinical Endocrinologists (AACE) feel that this number is not aggressive enough because it means the average blood sugar is running around 154 milligrams per deciliter and millimoles per liter. They recommend an A1C of 6.5 percent or less which gives you an average blood sugar above 126 milligrams per deciliter and millimoles per liter. Your husband’s A1C reading will play a significant role in preventing diabetes complications. Maintaining a lower Continue reading >>

Hemoglobin A1c With Eag Test

Hemoglobin A1c With Eag Test

$29.00 Sample Report Description: Hemoglobin A1C with eAG Test A Hemoglobin A1C test is used to measure glucose in the blood in the last 2-3 months. It can also be used to screen for or aid in the diagnosis of diabetes. Hemoglobin is a protein found in red blood cells that helps to carry oxygen from the lungs to other parts of the body. Sugars such as glucose link up with hemoglobin molecules causing them to become glycated. A Hemoglobin A1C test provides a measurement of a person's average blood glucose levels over the past 2-3 months by determining the percentage of their hemoglobin which is glycated. This test includes a calculation for estimated average glucose (eAG). EAG is a measurement which indicates a person's average daily blood sugar level. EAG is reported in the same units a person with Diabetes would see from the glucose meter they use to measure their own blood sugar. This measurement can give a person a more accurate assessment of how well they are managing their glucose levels because it is not based on single measurements taken at a specific time. The use of the Hemoglobin A1C with eAG test is endorsed by the American Diabetes Association. This test is typically ordered when someone is monitoring their ability to control their blood sugar. Your doctor may recommend having the Hemoglobin A1C test two to four times per year to monitor treatment. It is also useful as a periodic screening to assess a person's risk for developing Diabetes. Turnaround time for the Hemoglobin A1C test is typically 1 business day. Note: Result turn around times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance. Requirements: The Hemoglobin A1C test has no fasting req Continue reading >>

Glycated Hemoglobin

Glycated Hemoglobin

Glycated hemoglobin (hemoglobin A1c, HbA1c, A1C, or Hb1c; sometimes also referred to as being Hb1c or HGBA1C) is a form of hemoglobin that is measured primarily to identify the three-month average plasma glucose concentration. The test is limited to a three-month average because the lifespan of a red blood cell is four months (120 days). However, since RBCs do not all undergo lysis at the same time, HbA1C is taken as a limited measure of 3 months. It is formed in a non-enzymatic glycation pathway by hemoglobin's exposure to plasma glucose. HbA1c is a measure of the beta-N-1-deoxy fructosyl component of hemoglobin.[1] The origin of the naming derives from Hemoglobin type A being separated on cation exchange chromatography. The first fraction to separate, probably considered to be pure Hemoglobin A, was designated HbA0, the following fractions were designated HbA1a, HbA1b, and HbA1c, respective of their order of elution. There have subsequently been many more sub fractions as separation techniques have improved.[2] Normal levels of glucose produce a normal amount of glycated hemoglobin. As the average amount of plasma glucose increases, the fraction of glycated hemoglobin increases in a predictable way. This serves as a marker for average blood glucose levels over the previous three months before the measurement as this is the lifespan of red blood cells. In diabetes mellitus, higher amounts of glycated hemoglobin, indicating poorer control of blood glucose levels, have been associated with cardiovascular disease, nephropathy, neuropathy, and retinopathy. A trial on a group of patients with Type 1 diabetes found that monitoring by caregivers of HbA1c led to changes in diabetes treatment and improvement of metabolic control compared to monitoring only of blood or urine glu Continue reading >>

What Is A Hemoglobin A1c Test?

What Is A Hemoglobin A1c Test?

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. Why Are Hemoglobin A1c Tests Done? 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. How Is a Hemoglobin A1c Test Done? Most blood tests take a small amount of blood from a vein. To do that, a health professional will: clean the skin 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 Continue reading >>

What Does A1c Stand For?

What Does A1c Stand For?

You may have heard of a diabetes test called a hemoglobin A1c, sometimes called HgbA1c, HbA1c, or just A1C. What is an A1C test, and what should you know about it? HgbA1c is hemoglobin (pronounced HE-mo-glow-bin) that has sugar attached to it. Hemoglobin is the protein that carries oxygen from the lungs to all the cells of the body. Hemoglobin is an important component of red blood cells (RBCs). Nearly all cells in the human body need oxygen to power them. All animals with backbones, except one family of fish, have hemoglobin. Hemoglobin and molecules like it are also found in many invertebrates, plants, and fungi. Types of hemoglobin The “A” in Hemoglobin A (HgbA) stands for “adult.” After a person reaches six months of age, nearly all the hemoglobin is type A. About 98% of HgbA is type 1, or HgBA1. There is also HgBA2 (in addition to other types of hemoglobin), but not much. Type A1 has subtypes A1a, A1b, A1c, and others. Type A1c is the most common, making up about two-thirds of hemoglobin with glucose attached. HgbA1c is a good marker for glucose control, because the more glucose is circulating in the blood, the more hemoglobin will be glycated (covered with sugar). What an A1C test means Once hemoglobin is glycated, it stays that way until the red blood cell dies. Red blood cells live an average of three to four months. That is why your A1C level indicates your average glucose over the last few months. A1C results are expressed as the percentage of all hemoglobin that is glycated. An A1C of 7.0% means an average blood glucose level of 154 mg/dl, according to the American Diabetes Association (ADA). You can use this calculator to convert your A1C to an estimated average blood glucose number. However, A1C tests can sometimes mislead because: • Newer blood c Continue reading >>

Hemoglobin A1c Test (hba1c)

Hemoglobin A1c Test (hba1c)

Hemoglobin A1c, often abbreviated HbA1c, is a form of hemoglobin (a blood pigment that carries oxygen) that is bound to glucose. The blood test for HbA1c level is routinely performed in people with type 1 and type 2 diabetes mellitus. Blood HbA1c levels are reflective of how well diabetes is controlled. The normal range for level for hemoglobin A1c is less than 6%. HbA1c also is known as glycosylated, or glycated hemoglobin. HbA1c levels are reflective of blood glucose levels over the past six to eight weeks and do not reflect daily ups and downs of blood glucose. High HbA1c levels indicate poorer control of diabetes than levels in the normal range. HbA1c is typically measured to determine how well a type 1 or type 2 diabetes treatment plan (including medications, exercise, or dietary changes) is working. How Is Hemoglobin A1c Measured? The test for hemoglobin A1c depends on the chemical (electrical) charge on the molecule of HbA1c, which differs from the charges on the other components of hemoglobin. The molecule of HbA1c also differs in size from the other components. HbA1c may be separated by charge and size from the other hemoglobin A components in blood by a procedure called high pressure (or performance) liquid chromatography (HPLC). HPLC separates mixtures (for example, blood) into its various components by adding the mixtures to special liquids and passing them under pressure through columns filled with a material that separates the mixture into its different component molecules. HbA1c testing is done on a blood sample. Because HbA1c is not affected by short-term fluctuations in blood glucose concentrations, for example, due to meals, blood can be drawn for HbA1c testing without regard to when food was eaten. Fasting for the blood test is not necessary. What Are Continue reading >>

Hemoglobin A1c (hba1c) Test For Diabetes

Hemoglobin A1c (hba1c) Test For Diabetes

The hemoglobin A1c test tells you your average level of blood sugar over the past 2 to 3 months. It's also called HbA1c, glycated hemoglobin test, and glycohemoglobin. People who have diabetes need this test regularly to see if their levels are staying within range. It can tell if you need to adjust your diabetes medicines. The A1c test is also used to diagnose diabetes. Hemoglobin is a protein found in red blood cells. It gives blood its red color, and it’s job is to carry oxygen throughout your body. The sugar in your blood is called glucose. When glucose builds up in your blood, it binds to the hemoglobin in your red blood cells. The A1c test measures how much glucose is bound. Red blood cells live for about 3 months, so the test shows the average level of glucose in your blood for the past 3 months. If your glucose levels have been high over recent weeks, your hemoglobin A1c test will be higher. For people without diabetes, the normal range for the hemoglobin A1c level is between 4% and 5.6%. Hemoglobin A1c levels between 5.7% and 6.4% mean you have a higher change of getting of diabetes. Levels of 6.5% or higher mean you have diabetes. The target A1c level for people with diabetes is usually less than 7%. The higher the hemoglobin A1c, the higher your risk of having complications related to diabetes. A combination of diet, exercise, and medication can bring your levels down. People with diabetes should have an A1c test every 3 months to make sure their blood sugar is in their target range. If your diabetes is under good control, you may be able to wait longer between the blood tests. But experts recommend checking at least two times a year. People with diseases affecting hemoglobin, such as anemia, may get misleading results with this test. Other things that can Continue reading >>

What Is A1c? - Topic Overview

A1c is a test that shows the average level of blood sugar over the past 2 to 3 months. People who have diabetes need to have this test done regularly to see whether their blood sugar levels have been staying within a target range. This test is also used to diagnose diabetes. A1c test results show your average blood sugar level over time. The result is reported as a percentage. Your goal is to keep your hemoglobin A1c level as close to your target level as possible. You and your doctor will work together to set your safe target level. The result of your A1c test can also be used to estimate your average blood sugar level. This is called your estimated average glucose, or eAG. Your eAG and A1c show the same thing in two different ways. They both help you know about your average blood sugar over the past 2 to 3 months.

Your A1c Results: What Do They Mean?

Your A1c Results: What Do They Mean?

If you have diabetes, you should have an A1C test at least twice each year to find out your long-term blood glucose control. The A1C test measures your average blood glucose during the previous 2-3 months, but especially during the previous month. For people without diabetes, the normal A1C range is 4-6%. For people with diabetes, the lower the A1C value, the better the diabetes control and the lower the risk of developing complications such as eye, heart, and kidney disease. Your goal should be to have A1C values less than 7%. That may be a hard target to hit, but it is important to try because the lower your A1C, the lower your health risk. The table on this page shows what your A1C results say about your blood glucose control during the past few months. Some people are surprised when they have a high A1C result because when they check their blood glucose with their meter, they have relatively low numbers. But remember that checking your blood glucose gives you only a momentary sample of your blood glucose control. The A1C test measures your blood glucose control at all times during the previous 2-3 months, even times such as after meals or when you are asleep, when you don't usually check your blood glucose. Think of the A1C test as feedback to help you better control your diabetes and improve your diabetes care habits. By giving you important information about your long-term control, the A1C test can help you stay motivated to do your best on diabetes self care. Talk with your doctor and other members of the health care team about your A1C results and how you can use them to better manage diabetes. Within the next few months, the federal government will implement the first major reorganization of the Medicare system for many years: the Medicare Prescription Drug Imp 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 >>

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 >>

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 >>

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 >>

At Home A1c Testing Systems & Kits: Review

At Home A1c Testing Systems & Kits: Review

The A1C, a Glycated hemoglobin, is a form of hemoglobin that is measured primarily to identify the three-month average blood glucose concentration. The A1C test is limited to a three-month average because the lifespan of a red blood cell is only four months. In other words, it’s the indication of your blood sugar level for a three-month period. Typically, your doctor will test your A1C levels every 90 to 180 days depending on how well your blood sugar levels have been managed. In basic terms, the A1C test checks to see how much glucose is attaching to your red blood cells. You can work to keep your A1C within your target range using a recommended diabetes management regimen along with a well-managed diet, exercise routine and other healthy lifestyle . Normal a1C Prediabetes a1C Diabetic a1c Under 5.7 5.7 to 6.4 6.5 and above A1C Test Features and Pricing While most hospital conducted A1C tests cost around $86 per test (depending on your co-pay), you can now buy the A1C self-check home kit for around $40. Each kit includes one test with two strips, but you can buy a double test kit as well. The kits are not reusable so once you use your two lancets, you must buy another kit. Use Most people use this test every 30 days instead of waiting 90 days to be seen by the doctor. This helps patients have a more accurate reading on where their levels fall throughout the month. Insurance Coverage Most insurances will cover 1 or 2 tests per year and some hospitals will have a sample take-home A1C test that you can ask for. However, not all hospitals do so you may still need to buy over the counter kits depending on how many results a year you want to have or how many your doctor requires. Pros and Cons of Home Testing The A1C at home kit needs four large drops of blood which is eas Continue reading >>
