Hemoglobin Variants And The A1C Test

Some hemoglobin variants can affect some hba1c methods, but not all of them. for instance, certain variants can cause falsely high or low a1c test results depending on the method used. the a1c blood test, also called the hemoglobin a1c test, hba1c, or glycated hemoglobin test, reflects a person’s average blood glucose levels for the past 3. This assay provides accurate results for hemoglobin a1c in the presence of hemoglobin variants when hemoglobin a is also present. in patients with known hemoglobin variants without hemoglobin a, suggest monitoring long term glycemic control with fructosamine (arup test code: 0099012).. But some races and ethnicities have different types of hemoglobin, called hemoglobin variants. a hemoglobin variant doesn’t increase the risk for diabetes, but it can affect a1c results. labs have different ways to do a1c tests on blood with a hemoglobin variant..

The a1c test report also may include the result expressed in si units (mmol/mol) and an estimated average glucose (eag), which is a calculated result based on the hemoglobin a1c levels. the estimated average glucose (eag) reflects indirectly the glucose level over a period of 2-3 months before the a1c measurement.. Hemoglobin variants; the most common form of the oxygen-transporting hemoglobin protein is called hemoglobin a. the presence of other variants of the protein may result in inaccurate a1c test results. hemoglobin variants are more common among people of african, mediterranean or southeast asian descent.. Luckily, many labs now run a1c tests that are not affected by hemoglobin variants. there is a full list here . if you have a hemoglobin variant, you and your provider can work together to find a lab that will give you accurate a1c results..

The a1c test can be used to diagnose type 2 diabetes and prediabetes. 1 the a1c test is also the primary test used for diabetes management. an a1c test is a blood test that reflects your average blood glucose levels over the past 3 months. the a1c test is sometimes called the hemoglobin a1c, hba1c, glycated hemoglobin, or glycohemoglobin test.. Glycated hemoglobin (glycohemoglobin, hba1c, hemoglobin a1c, a1c, or less commonly hba 1c, hgba1c, hb1c, etc.) is a form of hemoglobin (hb) that is chemically linked to a sugar. most monosaccharides, including glucose, galactose and fructose, spontaneously (i.e. non-enzymatically) bond with hemoglobin, when present in the bloodstream of humans.however, glucose is less likely to do so than. If so, you can still have a1c tests done to monitor diabetes going forward, but they will need to be sent to a lab that uses a test that doesn’t show interference from hemoglobin variants. talk to your doctor about any questions or concerns you have about your a1c test result and what your next steps are..
