Hba1c – normal range, chart, blood test values, What is hba1c, this blood test helps find blood sugar levels and diagnose diabetes. The Diabetes Forum - find support, ask questions and share your experiences with 209,001 people. HbA1c refers to glycated haemoglobin (A1c), which identifies average plasma glucose concentration. 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.

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. Hemoglobin a1c testing for diabetes, Find out why the hemoglobin a1c test (hba1c) is so important for people with diabetes.. Why hemoglobin a1c is not a reliable marker, Hemoglobin a1c is being increasingly used as a way to screen for diabetes.

In previous blog posts, I wrote about quality professional Bill Howell’s diabetes diagnosis and how he managed his disease with Lean Six Sigma.
Hemoglobin HbA1c is a lab test that shows the average amount of sugar in blood cells over a 2-3 month period. In Minitab Statistical Software, he created histograms (Graph > Histogram) to show the distribution of the 6,493 HbA1c test results collected by the Centers for Disease Control and Prevention as part of their 2006 National Health and Nutrition Examination Survey. Howell noted that the interesting thing about this first chart was that it follows a normal distribution. The chart shows that of the 6,493 participants surveyed, 256 HbA1c test results were above the 7% cutoff. Because HbA1c is just one test in a battery of tests that are normally conducted when blood is drawn, Howell was also able to get the data behind the test results that concerned 27 other components of his blood, including blood glucose, total cholesterol, calcium, potassium, etc.
After getting his HbA1c levels back to a normal range of less than 7%, Howell used Minitab to calculate the correlation coefficients between all the blood components, and he found 18 strong relationships between HbA1c and the other blood components. Howell found that almost each blood component level was improved in some way as a result of having normal HbA1c levels. According to Howell, HbA1c levels can be normalized if you work with your physician, watch what you eat, and exercise moderately. Increasingly, doctors are giving patients their test results and with the introduction of the Australian Personally Controlled Electronic Health Records (PCEHR), this is expected to become even more commonplace. The abnormal results in this report are clearly marked in red and have a letter after them to show whether they are high (H) or low (L).
The results show a low haemoglobin, low haematocrit, low RCC (red cell count) and low MCV (mean cell volume) all of which are typical of iron deficiency anaemia and which would have been caused by the heavy periods.
If you look at the reference ranges you will see that these results are only just outside the limits and both of them are normal on the other two occasions tested. Here we have an example of a different type of pathology report, showing results from a 70-year old man with type 2 diabetes.
The results show a steady improvement in control of the diabetes with the final HbA1c in the non-diabetic range. These lab reports clearly mark abnormal results by printing them in a different colour and following them with an indicator showing whether they are high or low. If in doubt, talk to your doctor as results need to be interpreted in the context of all the other information available. Total Cholesterol is a soft, fat-like, waxy substance found in the bloodstreamand in all of your body’s cells. Glucose is a type of sugar that travels through the bloodstream and is the primary source of energy for your cells. Cortisol, a glucocorticoid (steroid hormone), is produced from cholesterol in the two adrenal glands located on top of each kidney. Creatinine is a chemical waste product in the blood that passes through the kidneys to be filtered and eliminated in urine.
TSH is produced by the pituitary gland, and is part of the body’s feedback system to maintain stable amounts of thyroid hormones. 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 can also be used to diagnose diabetes and can help diabetics manage their diabetes. Correlation is a measure of linear association between two variables, where values of -1 or 1 imply an exact linear relationship.
Through subsequent tests, he also found that his liver was healthier, his cholesterol levels were more favorable, and his blood pressure and pulse rate were lower.
All pathology reports contains certain compulsory information that is essential for interpreting your results.
It is important that you only use the reference range on the report from the lab that performed the analysis and not from any other source as reference ranges may differ between laboratories for some tests. Cholesterol is an important part of a healthybody because it’s used for producing cell membranes, some hormones andserves other needed bodily functions. Medical experts believe HDL carries LDL cholesterolaway from the arteries and removes excess cholesterol from arterial plaque, slowingits buildup. Nicotine is a chemical found in tobacco products, including cigarettes and chewing tobacco.
It is normally released in response to events and circumstances such as waking up in the morning, exercising and acute stress.
If an initial test concludes HbA1c levels are below 7%, then the test is considered normal and the person is likely a non-diabetic.
This first chart illustrates that the majority of the population tested wasn’t considered to be diabetic. This chart hit especially close-to-home for Howell, whose HbA1c test result of 15.3% would have fallen among the highest of all the people surveyed by the CDC. Keeping his HbA1c levels under 7% also reduced the pressure in his eyes, returning his vision to a more normal state, which allowed him to quit wearing highly corrective lenses. Individual pathology laboratories often add their own information and they can vary in the way they present it. See Reference ranges and what they mean for more information about how these are calculated and why they differ between laboratories. If you have enough tests done it is very likely that one or more results will fall just outside the reference range by chance. The results are followed by information provided by the laboratory to assist with interpretation of the results. Sometimes if treatment is too strict, blood sugar levels may fall to very low levels at times and this is potentially dangerous. There will however, always be some indicator of abnormality, most commonly an H for high or L for low but some labs may use other marks such as # or * signs to indicate the result is outside the reference range. Measuring cotinine in people's blood is the most reliable way to determine exposure to nicotine for both smokers and nonsmokers exposed to environmental tobacco smoke (ETS). However, if the initial test results show levels above 7%, there is evidence the person is diabetic. It also helped Howell understand where the 7% guideline came from as part of the HbA1c test for determining the existence of diabetes. While not all of these positive outcomes, including fewer leg cramps, an end to incessant thirst, etc., could be analyzed with correlation like the blood components could be, Howell found it amazing that so many aspects of his health were tied so closely to HbA1c levels. The A1C complex is formed when the glucose in the blood binds irreversibly to hemoglobin (glycates).
