HbAc blood test -

When blood sugar encounters red blood cells, it attaches itself to hemoglobin, where it remains. The hemoglobin A1C test measures the percentage of red blood cells in the bloodstream that have glucose attached to hemoglobin. A higher percentage of red blood cells containing glycated hemoglobin means that a person has higher levels of blood sugar in their bloodstream.

For people with diabetes, this means the disease is not well-controlled. For those who have not been diagnosed before, this may mean that they have prediabetes or diabetes. All people have some glycated hemoglobin within their red blood cells, and a lower percentage is considered normal.

After the blood is drawn, a lab will determine the test results and share that information with doctors and patients. If you have diabetes, the A1C test is the best way to check your average blood sugar levels over a three-month period to gauge whether or not you are managing your condition effectively.

Doctors may use one or more of these tests to diagnose prediabetes or diabetes. Although the A1C test is effective, people with certain health conditions may not get accurate results from it. Thus, another test should be used to confirm a diabetes or prediabetes diagnosis in those cases.

Certain medications or dietary supplements may also affect the test, giving people inaccurate results. They include:. To perform a hemoglobin A1C test, a sample of blood must be given, either by finger prick or simple blood draw.

Very few risks are associated with these blood-sampling methods. A bit of short-lived pain from the needle pricking the skin is normal and expected. Some people may develop a bruise at the site where the needle was inserted.

People with differing test results may be in an early stage of the disease, when blood glucose levels have not risen high enough to show up on every test. In this case, health care professionals may choose to follow the person closely and repeat the test in several months.

Lab test results can vary from day to day and from test to test. This can be a result of the following factors:. Your results can vary because of natural changes in your blood glucose level. For example, your blood glucose level moves up and down when you eat or exercise.

Sickness and stress also can affect your blood glucose test results. A1C tests are less likely to be affected by short-term changes than FPG or OGTT tests. The following chart shows how multiple blood glucose measurements over 4 days compare with an A1C measurement.

The straight black line shows an A1C measurement of 7. The blue line shows an example of how blood glucose test results might look from self-monitoring four times a day over a 4-day period.

Conditions that change the life span of red blood cells, such as recent blood loss, sickle cell disease , erythropoietin treatment, hemodialysis , or transfusion, can change A1C levels. A falsely high A1C result can occur in people who are very low in iron; for example, those with iron-deficiency anemia.

Other causes of false A1C results include kidney failure or liver disease. People in these groups may have a different type of hemoglobin, known as a hemoglobin variant, which can interfere with some A1C tests. Most people with a hemoglobin variant have no symptoms and may not know that they carry this type of hemoglobin.

Not all A1C tests are unreliable for people with a hemoglobin variant. People with false results from one type of A1C test may need a different type of A1C test to measure their average blood glucose level. The NGSP provides information for health care professionals about which A1C tests are appropriate to use for specific hemoglobin variants.

These factors tend to affect glucose measurements—fasting and OGTT—more than the A1C test. Health care professionals understand these variations and repeat lab tests for confirmation. Diabetes develops over time, so even with variations in test results, health care professionals can tell when overall blood glucose levels are becoming too high.

When repeated, the A1C test result can be slightly higher or lower than the first measurement. This means, for example, an A1C reported as 6. Health care professionals can visit ngsp. org to find information about the precision of the A1C test used by their lab. Your health care professional may use the A1C test to set your treatment goals, modify therapy, and monitor your diabetes management.

Experts recommend that people with diabetes have an A1C test at least twice a year. People will have different A1C targets, depending on their diabetes history and their general health.

You should discuss your A1C target with your health care professional. Studies have shown that some people with diabetes can reduce the risk of diabetes complications by keeping A1C levels below 7 percent. Managing blood glucose early in the course of diabetes may provide benefits for many years to come.

However, an A1C level that is safe for one person may not be safe for another. For example, keeping an A1C level below 7 percent may not be safe if it leads to problems with hypoglycemia , also called low blood glucose. Less strict blood glucose control, or an A1C between 7 and 8 percent—or even higher in some circumstances—may be appropriate in people who have.

Estimated average glucose eAG is calculated from your A1C. Some laboratories report eAG with A1C test results. The eAG number helps you relate your A1C to daily glucose monitoring levels.

Even though A1C results represent a long-term average, blood glucose levels within the past 30 days have a greater effect on the A1C reading than those in previous months. The National Institute of Diabetes and Digestive and Kidney Diseases NIDDK and other components of the National Institutes of Health NIH conduct and support research into many diseases and conditions.

Clinical trials are part of clinical research and at the heart of all medical advances. Clinical trials look at new ways to prevent, detect, or treat disease. Scientists are conducting research to learn more about diabetes, including studies about A1C. For example. Researchers also use clinical trials to look at other aspects of care, such as improving the quality of life for people with chronic illnesses.

The A1C test is also called the glycated hemoglobin, glycosylated hemoglobin, hemoglobin A1C or HbA1c test. An A1C test result reflects your average blood sugar level for the past two to three months. Specifically, the A1C test measures what percentage of hemoglobin proteins in your blood are coated with sugar glycated. Hemoglobin proteins in red blood cells transport oxygen.

Now the World Health Organisation WHO recommendsthat HbA1c can also be used to diagnose type 2 diabetes in people who were not previously known to have the condition. There are certain situations in which HbA1c cannot be used to diagnose diabetes.

An oral glucose tolerance test would be used as an alternative. The Department of Health recommends that everyone with diabetes has HbA1c measured at least twice a year. HbA1c may be measured more frequently in those who have just been diagnosed with diabetes, in those whose blood glucose remains too high, or when a treatment plan changes.

The test can also be used to diagnose type 2 diabetes. Please speak to your healthcare professional about local guidelines that may be in place, as there maybe variations in local procedures.

If you have an uncommon type of haemoglobin , known as a haemoglobin variant for example thalassaemia or sickle cell disease , accurate results will depend on the method used to measure HbA1c.

If you have haemolytic anaemia or heavy bleeding, your test results may be falsely low. If you are iron deficient, this may raise your HbA1c result. HbA1c is not used for diagnosis of diabetes during pregnancy.

HbA1c could be measured at home but this is rarely done, is expensive and should not be necessary if you are being monitored by your doctor. Therefore, results generated by different laboratories are traceable to this global standard, and comparable.

The HbA1c test is a simple blood test. The blood can be taken by your doctor or at a pathology lab. There is no need to fast before the test — you can eat and drink as normal. The results should be available within 24 hours. The test measures the percentage of haemoglobin that is bound to glucose, which reflects the average blood glucose concentration over last few months.

Abnormal results which would be higher than the normal range indicate a possible diagnosis of diabetes or poor control of diabetes.

If you are having an HbA1c test to help diagnose diabetes, a result of 6. A repeat test is often recommended to confirm the result, especially if you have no symptoms.

Your doctor will also want to talk with you about your lifestyle, such as your diet and how much physical activity you usually do. If you have known diabetes and your HbA1c is 6.

Most doctors would recommend that people with diabetes should aim for this range. However, some people may have a target HbA1c range that is slightly higher than this. If your levels are higher than your target range, that means that your blood sugar levels probably have not been well controlled recently.

Your doctor will want to talk to you about your current treatments and whether any adjustments need to be made. HbA1c is a simple blood test that does not require any fasting or other special preparation beforehand, and can be done at any time of the day.

This is compared with other tests that can be used in the diagnosis of diabetes. A fasting blood sugar level, as the name implies, requires you to fast not eat food or drink for a certain period of time before having the blood test.

An oral glucose tolerance test is another way to diagnose diabetes. It requires a special diet for 3 days before having the test, and then fasting overnight before the test. This test also involves having several blood tests over a couple of hours — before and after having to drink a certain volume of sweet liquid.
