HbAc levels -
This is because your blood sugar can vary wildly depending on the time of day, your activity levels, and even hormonal changes. Some people may have high blood sugar at 3 a. and be totally unaware of it. A1C tests became available in the s and quickly became an important tool in monitoring diabetes control.
A1C tests measure average blood glucose over the past 2 to 3 months. So even if you have a high fasting blood sugar, your overall blood sugar may be normal, or vice versa.
A normal fasting blood sugar may not eliminate the possibility of type 2 diabetes. This is why A1C tests are now being used for the diagnosis and screening of prediabetes and diabetes. The A1C test is also known as the hemoglobin A1c test or HbA1c test. Other names for the test include the glycosylated hemoglobin test, glycohemoglobin test, glycated hemoglobin test, or A1C.
A1C measures the amount of hemoglobin in the blood that has glucose attached to it. Hemoglobin is a protein found inside red blood cells that carries oxygen to the body. Hemoglobin cells are constantly dying and regenerating. Their lifespan is approximately 3 months.
Glucose attaches glycates to hemoglobin, so the record of how much glucose is attached to your hemoglobin also lasts for about 3 months. If the amount of glucose is normal, your A1C will be normal. Someone without diabetes will have about 5 percent of their hemoglobin glycated.
A normal A1C level is 5. A level of 5. People with diabetes have an A1C level of 6. The American Diabetes Association provides a calculator that shows how A1C levels correlate to glucose levels. To monitor overall glucose control, people with diabetes should have an A1C test at least twice a year.
The test is effective because of the lifespan of the hemoglobin cells. The glucose that was attached to the hemoglobin during the past 3 months will still be recorded by the test, since the cells live for approximately 3 months.
The A1C test provides an average of your blood sugar readings for the past 3 months. In the past, many different types of A1C tests gave different results depending on the lab that analyzed them.
But the National Glycohemoglobin Standardization Program has helped improve the accuracy of these tests. Manufacturers of A1C tests now have to prove that their tests are consistent with those used in a major diabetes study.
Accurate home test kits are also now available for purchase. But accuracy is relative when it comes to A1C or even blood glucose tests. The A1C test result can be up to half a percent higher or lower than the actual percentage.
That means if your A1C is 6, it might indicate a range from 5. Some people may have a blood glucose test that indicates diabetes but their A1C is normal, or vice versa. Before confirming a diagnosis of diabetes, your doctor should repeat the test that was abnormal on a different day. Some people may get false results if they have kidney failure , liver disease , or severe anemia.
Ethnicity can also influence the test. People of African, Mediterranean, or Southeast Asian descent may have a less common type of hemoglobin that can interfere with some A1C tests. A1C can also be affected if red cell survival is decreased.
Adults over the age of 45 should take an A1C test to get a baseline reading. High A1C levels are indicative of uncontrolled diabetes, which has been linked to an increased risk of the following conditions:. Starting an exercise program can help. Prediabetes can progress to diabetes. You may also need to make other lifestyle changes and monitor your daily blood glucose more closely.
Talk with your doctor about the best treatment plan for you. The A1C test measures the amount of hemoglobin in the blood that has glucose attached to it. The test provides an average of your blood sugar readings for the past 3 months.
People with diabetes should take an A1C test at least twice a year and more frequently in some cases. Read this article in Spanish.

A hemoglobin A1C HbA1C test is a blood test that shows what your average blood sugar glucose level was over the past two to three months.
Glucose is a type of sugar in your blood that comes from the foods you eat. Your cells use glucose for energy. A hormone called insulin helps glucose get into your cells. If you have diabetes your body doesn't make enough insulin, or your cells don't use it well. As a result, glucose can't get into your cells, so your blood sugar levels increase.
Glucose in your blood sticks to hemoglobin, a protein in your red blood cells. As your blood glucose levels increase, more of your hemoglobin will be coated with glucose. An A1C test measures the percentage of your red blood cells that have glucose-coated hemoglobin.
High A1C levels are a sign of high blood glucose from diabetes. Diabetes can cause serious health problems , including heart disease , kidney disease , and nerve damage. But with treatment and lifestyle changes, you can control your blood glucose levels. An A1C test may be used to screen fo r or diagnose:.
If you have diabetes or prediabetes, an A1C test can help monitor your condition and check how well you've been able to control your blood sugar levels.
A health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial.
You may feel a little sting when the needle goes in or out. This usually takes less than five minutes. There is very little risk to having a blood test.
You may have slight pain or bruising at the spot where the needle was put in, but most symptoms go away quickly. A1C results tell you what percentage of your hemoglobin is coated with glucose.
The percent ranges are just a guide to what is normal. What's normal for you depends on your health, age, and other factors. Ask your provider what A1C percentage is healthy for you. Providers often use more than one test to diagnose diabetes.
So, if your test result was higher than normal, you may have another A1C test or a different type of diabetes test , usually either a fasting blood glucose test or an oral glucose tolerance test OGTT.
If your A1C test was done to monitor your diabetes, talk with your provider about what your test results mean. Learn more about laboratory tests, reference ranges, and understanding results.
The A1C test is not used to diagnose gestational diabetes or type 1 diabetes. Also, if you have a condition that affects your red blood cells, such as anemia or another type of blood disorder , an A1C test may not be accurate for diagnosing diabetes. Kidney failure and liver disease can also affect A1C results.
In these cases, your provider may recommend different tests to diagnose diabetes and prediabetes.

Hemoglobin A1C HbA1c Test.
What is a hemoglobin A1C HbA1C test? An A1C test can show your average glucose level for the past three months because: Glucose sticks to hemoglobin for as long as the red blood cells are alive. Red blood cells live about three months. Other names: HbA1C, A1C, glycohemoglobin, glycated hemoglobin, glycosylated hemoglobin.
What is it used for? An A1C test may be used to screen fo r or diagnose: Type 2 diabetes. With type 2 diabetes your blood glucose gets too high because your body doesn't make enough insulin to move blood sugar from your bloodstream into your cells, or because your cells stop responding to insulin.
Prediabetes means that your blood glucose levels are higher than normal, but not high enough to diagnosed as diabetes. Lifestyle changes, such as healthy eating and exercise , may help delay or prevent prediabetes from becoming type 2 diabetes. Why do I need an HbA1C test?
The Centers for Disease Control CDC recommends A1C testing for diabetes and prediabetes if: You are over age If your results are normal, you should repeat the test every 3 years.
