If you currently have diabetes, your A1c goal may be 8% or lower.
The A1C is a blood test that gives us an estimated average of what your blood sugar has been over the past months. 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. 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. Think about a car that has a gas leak. When you eat, some of the food is broken down into sugar and goes into your bloodstream.
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.
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. 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. Just had a routine physical last week and got complete blood work done.
My test results for my hemaglobin a1c levels were elevated at 5. There's some history of diabetes in my family, but only by people who are obese. I'm roughly on the BMI so I could definitely lose 5 - 10 pounds - but I had no idea that would put me in the prediabetic range. I also exercise times a week by running a few miles. Not sure what I'm doing here that is triggering higher hemaglobin levels -- how worried or proactive do I need to be here?
Just exercise even more and try to get my BMI down even more? I don't really count carbs, but don't think I eat that many don't eat much pasta or white bread. Do I just need to be a stickler and start counting them?
Also, not every adult diagnoses as Type 2 indeed are. Some are misdiagnosed due to age and turn out to be adult onset Type 1. In your shoes, I be looking at charting your diet as it is easy to be eating more of something than you realise. A web site like MyFitnessPal is free and will chart your carbs, plus has an international database that make it easy to find the carb content in foods that aren't labelled.
An A1C blood test measures average blood sugar levels over the past 2 to 3 months. A1C tests are also used to monitor diabetes treatment plans. What is an A1C test? An A1C test measures how well the body is maintaining blood glucose levels. To do this, an A1C test averages the percentage of sugar-bound hemoglobin in a blood sample.
When glucose enters the blood, it binds to a red blood cell protein called hemoglobin. The higher blood glucose levels are, the more hemoglobin is bound.
Red blood cells live for around 4 months, so A1C results reflect long-term blood glucose levels. A1C tests are done using blood obtained by a finger prick or blood draw. Physicians will usually repeat A1C tests before diagnosing diabetes. Initial A1C tests help physicians work out an individual's baseline A1C level for later comparison. How often A1C tests are required after diagnosis varies depending on the type of diabetes and management factors.
Lowering A1C levels Many studies have shown that lowering A1C levels can help reduce the risk or intensity of diabetes complications. With type 1 diabetes, more controlled blood glucose levels are associated with reduced rates of disease progression.
With type 2 diabetes, more controlled A1C levels have also been shown to reduce symptoms affecting the small arteries and nerves in the body. This influences eyesight and pain while decreasing complications. Long-term studies have also shown that early and intensive blood glucose control can reduce cardiovascular complications in people with type 1 or 2 diabetes.
Even small changes in A1C levels can have big effects. 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. Hemoglobin A1c levels are routinely used to determine blood sugar control over time in people with diabetes.
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. 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.
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.
Hemoglobin A1c levels between 5. Levels of 6. 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. Your A1C is a blood test that provides information about your average blood sugar levels over the past three months. Your provider and diabetes care team use this number to gauge how things are going and if and how to tweak your diabetes treatment plan.
