What is the purpose of the HbA1c Blood Test? The HbA1c test is a blood test that can give a good indication of how well diabetes is controlled over a period of time (approximately six to eight weeks). HbA1c is also known as glycosylated haemoglobin. Haemoglobin (theHbin HbA1c) is a protein in the blood which carried oxygen to the organs and gives the blood its red colour. Glucose in the bloodstream can attach itself to some of these haemoglobin molecules, creating glycosylated haemoglobin. (Glycosylated basically means attached to glucose). The higher the glucose levels in the body, the greater the proportion of haemoglobin molecules that become attached to glucose. The proportion of haemoglobin in the blood that is attached to glucose will indicate the average blood glucose levels over the previous weeks to months. Blood glucose tests are vital for the detection and management of diabetes, but their usefulness is limited by the fact that they only show the glucose level at the time of the test or a snapshot view. The HbA1c test is a bit like a time-exposure and will give an indication of the average blood glucose levels over a period of time. Higher readings in the HbA1c test indicate higher average blood glucose levels i.e. poorer control of diabetes. If your HbA1c result is higher than the target set for you, this would mean that you may be at higher of developing complications from diabetes. The HbA1c test is a blood test that uses a small drop of blood from the tip of the finger. Your result is available straight away. The test is fully validated for accuracy and is carried out to the highest standards. Price of HbA1c blood test at McCabes Pharmacy: 45 Continue reading >>

Evaluating the long-term control of blood glucose concentrations in diabetic patients Diagnosing diabetes Identifying patients at increased risk for diabetes (prediabetes) Diabetes mellitus is a chronic disorder associated with disturbances in carbohydrate, fat, and protein metabolism characterized by hyperglycemia. It is one of the most prevalent diseases, affecting approximately 24 million individuals in the United States. Long-term treatment of the disease emphasizes control of blood glucose levels to prevent the acute complications of ketosis and hyperglycemia. In addition, long-term complications such as retinopathy, neuropathy, nephropathy, and cardiovascular disease can be minimized if blood glucose levels are effectively controlled. Hemoglobin A1c (HbA1c) is a result of the nonenzymatic attachment of a hexose molecule to the N-terminal amino acid of the hemoglobin molecule. The attachment of the hexose molecule occurs continually over the entire life span of the erythrocyte and is dependent on blood glucose concentration and the duration of exposure of the erythrocyte to blood glucose. Therefore, the HbA1c level reflects the mean glucose concentration over the previous period (approximately 8-12 weeks, depending on the individual) and provides a much better indication of long-term glycemic control than blood and urinary glucose determinations. Diabetic patients with very high blood concentrations of glucose have from 2 to 3 times more HbA1c than normal individuals. Diagnosis of diabetes includes 1 of the following: -Fasting plasma glucose > or =126 mg/dL -Symptoms of hyperglycemia and random plasma glucose >or =200 mg/dL -Two-hour glucose > or =200 mg/dL during oral glucose tolerance test unless there is unequivocal hyperglycemia, confirmatory testing should be Continue reading >>

Hba1c Test For Diabetes

Tweet The HbA1c test, also known as the haemoglobin A1c or glycated haemoglobin test, is an important blood test that gives a good indication of how well your diabetes is being controlled. Together with the fasting plasma glucose test, the HbA1c test is one of the main ways in which type 2 diabetes is diagnosed. HbA1c tests are not the primary diagnostic test for type 1 diabetes but may sometimes be used together with other tests. For HbA1c guidelines for monitoring diabetes control, see our HbA1c targets page. HbA1c testing in diagnosing diabetes The World Health Organisation (WHO) suggests the following diagnostic guidelines for diabetes: HbA1c below 42 mmol/mol (6.0%): Non-diabetic HbA1c between 42 and 47 mmol/mol (6.0–6.4%): Impaired glucose regulation (IGR) or Prediabetes HbA1c of 48 mmol/mol (6.5%) or over: Type 2 diabetes If your HbA1c test returns a reading of 6.0–6.4%, that indicates prediabetes. Your doctor should work with you to suggest appropriate lifestyle changes that could reduce your risk of developing type 2 diabetes. HbA1c is not used to diagnose gestational diabetes in the UK. Instead, an oral glucose tolerance test is used. A random blood glucose test will usually be used to diagnose type 1 diabetes. However, in some cases, an HbA1c test may be used to support a diagnosis of type 1 diabetes. People with diabetes who reduced their HbA1c by less than 1% can cut their risk of dying within 5 years by 50%, according to Swedish research presented at the annual meeting of the European Association for the Study of Diabetes, Sept. 2012 (EASD). How is HbA1c tested? To measure a person's HbA1c level, a blood sample is taken from the patient's arm, and used to produce a reading. In some cases, such as with HbA1c testing for children, a single droplet of blo Continue reading >>

An Important Blood Test You Probably Dont Know About: Hba1c

An Important Blood Test You Probably Dont Know About: Hba1c

HbA1c is probably one of the most important blood test results that is central to overall health. Most people have never heard of it, and unless you are diabetic, it is unlikely your doctor will request it. So, what is HbA1c and why is it important? HbA1c is a term commonly used in relation to diabetes. In addition to being useful in the diagnosis of diabetes and useful in monitoring the response of treatment in diabetic patients, HbA1c is also a helpful blood test for those without diabetes as it can give important information about ones health generally, particularly ones risk of heart disease, cancer and Alzheimers disease. So, lets start with an explanation of what HbA1c is. This video has everything you need to know about this blood test. The term HbA1c refers to glycated haemoglobin. Red blood cells contain haemoglobin that carries oxygen around the body. At any one time, a small proportion of the glucose in our blood permanently binds to the haemoglobin and the haemoglobin that permanently carries a glucose molecule is said to be glycated. The level or percentage of glycated haemoglobin is proportional the level or concentration of glucose in the blood. So, the higher the blood glucose level, the higher the level of glycated haemoglobin. Red blood cells are continually renewed and recycled. Because red blood cells last about 10-12 weeks, the level of glycated haemoglobin (HbA1c) in a blood sample is a measure of blood glucose levels during the 10-12 weeks before the blood test. This is often referred to as the estimated average glucose (eAG). HbA1c can identify people with prediabetes and diabetes. So, an HbA1c below 42mmol/mol (or 6.0%) is regarded as normal. People with prediabetes have a level of between 42 and 47 mmol/mol (6.0 to 6.4%) and people with diabet Continue reading >>

Hba1c

Hba1c

At a glance Also known as Haemoglobin A1c; glycated haemoglobin; glycosylated haemoglobin Why get tested? To diagnose diabetes, to monitor a person's diabetes and to aid in treatment decisions When to get tested? When first diagnosed with diabetes and every 3-6 months Sample required? A blood sample drawn from a vein in the arm or from a fingerstick Test preparation needed? None What is being tested? As glucose circulates in your blood, some of it spontaneously binds to haemoglobin (the protein that carries oxygen in your red blood cells). This combination is called haemoglobin A1c (HbA1c). The amount of HbA1c formed is directly related to the amount of glucose in your blood. If your diabetes is not well controlled, your blood glucose levels are high, causing higher HbA1c levels. HbA1c levels do not change quickly since red blood cells live for 3-4 months. Because of this, the amount of HbA1c in your blood reflects the average amount of glucose in your blood during the last few months. How is the sample collected for testing? Your blood may be drawn from a vein in your arm or, in some cases, a drop of blood from a finger-prick may be used. Is any test preparation needed to ensure the quality of the sample? No test preparation is needed. How is it used? The test for HbA1c can be used to diagnose diabetes and also indicates how well your diabetes has been controlled over the last few months. Even though you may have some very high or very low blood glucose values, HbA1c will give you a picture of the average amount of glucose in your blood over that time period. The result can help you and your doctor know if the measures you are taking to control your diabetes are working. When your doctor suspects that you might have diabetes. After diabetes has been diagnosed Diabetes Continue reading >>

What Is The Hba1c?

What Is The Hba1c?

In the blood stream are the red blood cells, which are made of a molecule, haemoglobin. Glucose sticks to the haemoglobin to make a 'glycosylated haemoglobin' molecule, called haemoglobin A1C or HbA1C. The more glucose in the blood, the more haemoglobin A1C or HbA1C will be present in the blood. Red cells live for 8 - 12 weeks before they are replaced. By measuring the HbA1C it can tell you how high your blood glucose has been on average over the last 8-12 weeks. A normal non-diabetic HbA1C is <36mmol/mol (5.5%). In diabetes about 48mmol/mol (6.5%) is good. The HbA1C test is currently one of the best ways to check diabetes is under control; it is the blood test that gets sent to the laboratory, and it is done on the spot in some hospital clinics. Remember, the HbA1C is not the same as the glucose level. Coincidentally the glucose/HbA1C numbers for good control are rather similar though in the UK and Europe: glucose levels averaging 6.5 mmols/l before meals is equivalent to 60mmol/mol (7%). HbA1C (glucose levels are higher after meals) (see below). Two examples Below are two examples of people who have their HbA1c measured. One is poorly controlled, one well controlled. When should the HbA1C be measured? Measure HbA1c every 3 months if trying to improve every 6 months if very stable If your diabetes is controlled (basically an HbA1C lower than 53mmol/mol ( 7% ), every 3-6 months. But if the last reading is above 53mmol/mol (7%) and you are in reasonable health, you will need to achieve a lower level if possible, and the next reading should be sooner. This assumes you will make changes to improve your control. There is no point in having your HbA1c measured if you are not trying to achieve good control of your diabetes, although the level does predict the likelihood of co Continue reading >>

The A1c Test & Diabetes

The A1c Test & Diabetes

What is the A1C test? The A1C test is a blood test that provides information about a person’s average levels of blood glucose, also called blood sugar, over the past 3 months. The A1C test is sometimes called the hemoglobin A1c, HbA1c, or glycohemoglobin test. The A1C test is the primary test used for diabetes management and diabetes research. How does the A1C test work? The A1C test is based on the attachment of glucose to hemoglobin, the protein in red blood cells that carries oxygen. In the body, red blood cells are constantly forming and dying, but typically they live for about 3 months. Thus, the A1C test reflects the average of a person’s blood glucose levels over the past 3 months. The A1C test result is reported as a percentage. The higher the percentage, the higher a person’s blood glucose levels have been. A normal A1C level is below 5.7 percent. Can the A1C test be used to diagnose type 2 diabetes and prediabetes? Yes. In 2009, an international expert committee recommended the A1C test as one of the tests available to help diagnose type 2 diabetes and prediabetes.1 Previously, only the traditional blood glucose tests were used to diagnose diabetes and prediabetes. Because the A1C test does not require fasting and blood can be drawn for the test at any time of day, experts are hoping its convenience will allow more people to get tested—thus, decreasing the number of people with undiagnosed diabetes. However, some medical organizations continue to recommend using blood glucose tests for diagnosis. Why should a person be tested for diabetes? Testing is especially important because early in the disease diabetes has no symptoms. Although no test is perfect, the A1C and blood glucose tests are the best tools available to diagnose diabetes—a serious and li Continue reading >>

Testing For Diabetes: What Your Hba1c Levels Mean

Testing For Diabetes: What Your Hba1c Levels Mean

Testing for diabetes: what your HbA1c levels mean The test for Type 2 diabetes is quick and easyCredit:Tom Merton The basic tests to diagnose Type 2 diabetes are effective and very fast. However, often the illness is first diagnosed by chance, when a patient is being tested for something else. That was certainly true for 48-year-old Stacy Evans, a father of three, who works in sales in Milton Keynes. Evans, whose partner Debbie Barks, 51, works for the NHS, says: In 2012, I went to register with a new GP and had a urine test as part of the process. I didnt know anything about type 2 diabetes so wasnt then aware of having any symptoms. But my blood sugar readings were off the scale, apparently. "As I learnt about the disease, I realised that not only was I at high risk, as I was massively overweight and unfit, but also I was exhibiting classic symptoms. I needed to go to the toilet three or four times a night, for example. Other symptoms include a constant thirst, weight loss and excessive tiredness. Stacy Evans, 48, was diagnosed with Type 2 diabetes in 2012Credit:Rii Schroer/The Telegraph Evans was so unaware of what type 2 diabetes meant he wasnt even shocked. I had no idea how serious it could be. He later learnt that the condition which occurs when the body is unable to produce enough insulin or unable to use what insulin it does produce to control blood sugar levels can have serious consequences, including organ damage and coma. Healthy blood sugar levels from a diabetes test should be between 4.0 to 6.0 mmol/L (millimoles per litre) when fasting or up to 7.8 mmol/L two hours after eating a meal, according to the NHS. But when doctors took Evanss blood, they calculated his blood sugar levels at 17mmol/l. Evans was immediately put on to medication that makes the bo Continue reading >>

Hba1c Testing

Hba1c Testing

The HbA1c test measures your average blood glucose over the previous 8 to 12 weeks and gives an indication of your longer-term blood glucose control. It is used as a screening test to identify diabetes and regular monitoring tool if you have been diagnosed with diabetes. How useful is the test? HbA1c reflects the average plasma glucose (sugar in your bloodstream) over the previous 8 to 12 weeks and measures how much glucose has become stuck onto your red blood cells.(1) It can be performed at any time of the day and does not require any special preparation such as fasting. In recent years, the HbA1c test has become the preferred test for screening and diagnosis of diabetes. In 2011, the HbA1c test in New Zealand was updated to measure in millimoles per mole (mmol/mol) to align with a shift internationally (2). Prior to this, it used to be measured as a percentage (%) and you may still hear people refer to these units at times. The images below show the new and old units. Learning what your target range for HbA1c is very important. Having regular HbA1c tests helps both you and your healthcare team monitor how well your diabetes is controlled and whether any changes in lifestyle or medication are needed. Diagnosing prediabetes and diabetes As a general guide, HbA1c levels of: Less than or equal to 40 mmol/mol is normal. 41 to 49 mmol/mol is prediabetes or 'impaired fasting glucose'. 50 mmol/mol and above suggests diabetes (if symptomatic. If no symptoms of diabetes, two tests on separate occasions are needed). (3) Read more about prediabetes, type 1 diabetes and type 2 diabetes. What are healthy HbA1c levels for people with diabetes? An ideal range or target HbA1c level will vary from person to person and depends on age, type of diabetes and other health conditions or sta Continue reading >>

Guide To Hba1c

Guide To Hba1c

Tweet HbA1c is a term commonly used in relation to diabetes. This guide explains what HbA1c is, how it differs from blood glucose levels and how it's used for diagnosing diabetes. What is HbA1c? The term HbA1c refers to glycated haemoglobin. It develops when haemoglobin, a protein within red blood cells that carries oxygen throughout your body, joins with glucose in the blood, becoming 'glycated'. By measuring glycated haemoglobin (HbA1c), clinicians are able to get an overall picture of what our average blood sugar levels have been over a period of weeks/months. For people with diabetes this is important as the higher the HbA1c, the greater the risk of developing diabetes-related complications. HbA1c is also referred to as haemoglobin A1c or simply A1c. HbA1c refers to glycated haemoglobin (A1c), which identifies average plasma glucose concentration. How does HBA1c return an accurate average measurement of average blood glucose? When the body processes sugar, glucose in the bloodstream naturally attaches to haemoglobin. The amount of glucose that combines with this protein is directly proportional to the total amount of sugar that is in your system at that time. Tweet Type 2 diabetes mellitus is a metabolic disorder that results in hyperglycemia (high blood glucose levels) due to the body: Being ineffective at using the insulin it has produced; also known as insulin resistance and/or Being unable to produce enough insulin Type 2 diabetes is characterised by the body being unable to metabolise glucose (a simple sugar). This leads to high levels of blood glucose which over time may damage the organs of the body. From this, it can be understood that for someone with diabetes something that is food for ordinary people can become a sort of metabolic poison. This is why peop 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

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 Hba1c?

What Is Hba1c?

HbA1c, also known as haemoglobin A1c, is haemoglobin with glucose that has attached itself in the blood cell. HbA1c evaluates the average amount of glucose in the blood over the last two to three months. Haemoglobin is the protein that transports oxygen within red blood cells. There are several different types of haemoglobin in which the predominant form (approximately 95-98%) is haemoglobin A. The glucose that circulates in the blood binds to the haemoglobin A, and thereby forms HbA1c. The higher the level of glucose is in the blood, the more HbA1c is formed. As haemoglobins lifespan is around 120 days, HbA1c survives the same amount of time. HbA1c is created on a daily basis and slowly degrades as the older red blood cells dies and the young red cells take their place. Why do we analyse HbA1c? An HbA1c test can be used to screen for and diagnose diabetes or even define the risk profile of developing diabetes. This test is also used to monitor a treatment for someone who has been diagnosed with diabetes. Therefore it helps to evaluate a person's glucose level over time. European Association for the Study of Diabetes (EASD) recommends that the management of glucose levels in type 2 diabetes should be more patient-centred. It is recommended to cooperate with your health care provider to select a goal that reflects each person's individual health status and balance risks and benefits. HbA1c can be used to monitor glucose levels in diabetics over time. The goal of those with diabetes is to keep their blood sugar levels as close to normal as possible. This helps to minimize the complications caused by chronically elevated glucose levels, such as progressive damage to body organs like kidneys, eyes, cardiovascular system, and nerves. HbA1c test results give a picture of the Continue reading >>
