Hemoglobin a1c test: get information about the results, Hemoglobin a1c test is used as a standard tool to determine blood sugar control for patients with diabetes.
A1c test: medlineplus medical encyclopedia, A1c is a lab test that shows the average level of blood sugar (glucose) over the previous 3 months. The hemoglobin A1c test, also called the HbA1c, glycated hemoglobin, or glycohemoglobin test, is an important blood test used to determine how well your diabetes is being controlled. For people without diabetes, the normal range for the hemoglobin A1c test is between 4% and 5.6%.
The higher the hemoglobin A1c, the higher the risks of developing complications related to diabetes. It is important to note, however, that patients with diseases affecting hemoglobin levels, such as anemia, may get abnormal test results.
If you are a pre-diabetic, your blood sugar can be brought down to normal levels with simple lifestyle modifications.
If you are a diabetic, your goal is to maintain your blood sugar within the target range specified for you by your doctor. Healthalyze can determine optimal times for you to test your blood sugar and remind you when to go for a screening.
Some people may benefit from taking metformin (glucophage) tablet in addition to the lifestyle modifications changes to prevent diabetes development.

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. Because red blood cells in the human body survive for 8-12 weeks before renewal, measuring glycated haemoglobin (or HbA1c) can be used to reflect average blood glucose levels over that duration, providing a useful longer-term gauge of blood glucose control. If your blood sugar levels have been high in recent weeks, your HbA1c will also be greater. Note that this is a general target and people with diabetes should be given an individual target to aim towards by their health team. An individual HbA1c should take into account your ability to achieve the target based on your day to day life and whether you are at risk of having regular or severe hypos. HbA1c provides a longer-term trend, similar to an average, of how high your blood sugar levels have been over a period of time. An HbA1c reading can be taken from blood from a finger but is often taken from a blood sample that is taken from your arm. Blood glucose level is the concentration of glucose in your blood at a single point in time, i.e.
This is measured using a fasting plasma glucose test, which can be carried out using blood taken from a finger or can be taken from a blood sample from the arm. However, fasting glucose tests provide an indication of your current glucose levels only, whereas the HbA1c test serves as an overall marker of what your average levels are over a period of 2-3 months.
HbA1c is a measure of how well controlled your blood sugar has been over a period of about 3 months. Some people may be set less challenging targets by their doctor, particularly where hypoglycemia is a concern. Everyone with diabetes mellitus in the UK should be offered an HbA1c test at least once a year. Although HbA1c level alone does not predict diabetes complications, good control is known to lower the risk of complications.
It is important to note that because blood glucose levels fluctuate constantly, literally on a minute by minute basis, regular blood glucose testing is required to understand how your levels are changing through the day and learning how different meals affect your glucose levels.

The HbA1c test (also called glycosylated haemoglobin level) is a laboratory blood test which measures your average blood glucose over the previous weeks and gives an indication of your longer-term blood glucose control. Most diabetes specialists and GPs have a lot of confidence in this test and will use it to help show people with type 1 or type 2 diabetes how they are going with their blood glucose management. 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.

Testing should be carried out in a health care setting (such as your doctor’s office or a lab). The OGTT is a two-hour test that checks your blood glucose levels before and 2 hours after you drink a special sweet drink. Before people develop type 2 diabetes, they almost always have "prediabetes" — blood glucose levels that are higher than normal but not yet high enough to be diagnosed as diabetes. Doctors sometimes refer to prediabetes as impaired glucose tolerance (IGT) or impaired fasting glucose (IFG), depending on what test was used when it was detected. Some people with prediabetes may have some of the symptoms of diabetes or even problems from diabetes already.

The A1C test is a blood test that reflects the average blood-glucose level over the last two to three months.
In 1950s, hemoglobin A1c was identified as one of the largest fractions of the minor components of normal adult hemoglobin. Hemoglobin is a protein in the red blood cell, which transports oxygen from your lungs to the whole body. HbA1c is a simple blood test measures the percentage of hemoglobin variant “A’ subtype ‘1c” that has been attached to the glucose in the blood. However, blood-glucose levels in the preceding 30 days can make more effect in the A1C than the 90 to 120 days earlier. If you are having A1C percentage, it looks less meaning, until you convert it into equivalent blood-glucose level help provide more meaning.
HbA1c tests can easily do with a regular finger stick or a blood sample drawn from a vein in your arm like testing for blood glucose. Laboratories should be aware of their method limitations with respect to interference from the most prevalent Hb variants. Decrease or increase in erythrocyte (decrease in RBC) can make you A1C to lower or increase respectively. Hb Variants - Hemoglobin S trait, which affects about 8% of African Americans, hemoglobin C trait, which affects approximately 3% of African Americans, and hemoglobin E trait, which affects 10% to more than 50% of Southeast Asians in California, are all reported to affect some HbA1c assay methods.
Vitamin C & E ingestion interfered with some assay methods and falsely decreasing results. A splenectomy is a surgical procedure that partially or completely removes the spleen, will falsely raise A1C.
Bone marrow conditions - include leukemia, multiple myeloma (cancer of the plasma cells in bone marrow), and lymphoma (blood cancer). Nutritional deficiencies such as iron, copper, foliate vitamins B6 and B12 can falsely affect the result. Once A1C interferences are recognized; choosing an alternative form of testing, such as glycated serum protein testing (fructosamine or glycated albumin) can help assess glycaemia better. Many people have a question, what does it mean if I have a high A1C and normal blood sugars?
Hemoglobin A1c levels provide an average of your blood sugar control over a six to 12 week period and is used in conjunction with home blood sugar monitoring to make adjustments in your diabetes medicines. When someone has uncontrolled diabetes, the excess glucose in their blood binds to the hemoglobin, that is, it becomes "glycated". Thus, people with diabetes should have this test every 3 months to determine whether their blood sugar is under control. Other factors that can affect the measures of hemoglobin A1c include supplements such as vitamins C and E, high cholesterol levels, and kidney or liver disease. Since HbA1c measures the average effect of blood sugar levels in the past several weeks, immediate changes in blood sugar do not affect the results.
If you are not a diabetic or pre-diabetic, get yourself screened at appropriate intervals with an FBS or HbA1c test to keep track of your sugar levels.

It can also help you track your blood sugar and recommend lifestyle modifications to manage your condition. At this stage, the blood glucose level is higher than normal, but has not yet reached a level that is sufficient to be diagnosed as a diabetic (i.e. OGTT involves drinking a glucose rich beverage (75 grams of carbohydrates) and measurement of blood glucose immediately after 2 hours. Losing even (5-10 percent of your total body weight), through healthy eating (low calories with low fat intake), and regular exercise (at least 150 minutes per week) can prevent diabetes by up to 58 percent in two studies. Your blood glucose level should be assessed yearly by your doctor and not through the use of the self blood glucose meter. He writes articles about Diabetes, How To control it, How to live a healthier life style plus on other health and fitness topics. This guide explains what HbA1c is, how it differs from blood glucose levels and how it's used for diagnosing diabetes. It develops when haemoglobin, a protein within red blood cells that carries oxygen throughout your body, joins with glucose in the blood, becoming 'glycated'. It essentially gives a good idea how high or low, on average, your blood glucose levels have been.
This may be more likely if you have recently had your medication changed or your health team are otherwise wishing to monitor your diabetes control more than once a year. The test is used as a regular monitoring tool if you have been diagnosed with diabetes. It may also be used as one of several screening measures in the general population to look for elevated blood glucose levels, which are suggestive of diabetes. Association of glycaemia with macrovascular and microvascular complications of type 2 diabetes (UKDPS 35): prospective observational study.
If your doctor determines that your blood glucose level is very high, or if you have classic symptoms of high blood glucose in addition to one positive test, your doctor may not require a second test to diagnose diabetes.
The advantages of being diagnosed this way are that you don't have to fast or drink anything. Fasting means after not having anything to eat or drink (except water) for at least 8 hours before the test. This condition puts you at a higher risk for developing type 2 diabetes and cardiovascular disease. For some people with prediabetes, early treatment can actually return blood glucose levels to the normal range.
Followed by different discoveries and in 1976, Koenig and colleagues demonstrated that HbA1c concentration was an indicator of fasting blood-glucose concentrations.
Elevated hemoglobin F, which is associated with thalassemia syndromes, also affects some assay methods. Unfortunately, factors affecting the accuracy of HbA1c measurement may not be recognized clinically. Many others, on the other hand, have a question, what does it means if I have normal A1C and high fasting glucose?
The average amount of sugar in your blood in the last several weeks is reflected in hemoglobin A1c level: the higher your blood sugar in recent weeks, the higher the amount of hemoglobin A1c.
Even those with control over their diabetes it is recommended to have this test performed at least twice a year.
Therefore, unlike most other blood sugar tests used in diabetes, fasting is not required for HbA1c tests. Of course should you develop any symptoms of diabetes, you need to consult your doctor early. Red blood cells have a lifespan of about six weeks and so the test gives a good indication of what your overall blood glucose levels have been throughout that time. Your gift today will help us get closer to curing diabetes and better treatments for those living with diabetes. The blood-glucose level decides the volume of glycosylation reaction and the level of glycated hemoglobins. Home tests are now available too; they are subject to inaccuracy, if not conducted exactly as stated in the instructions.
As with any laboratory test, any result that does not fit the clinical picture should require investigation further with the clinician. Not everyone with prediabetes will develop type 2 diabetes, but many of them will in the future.
