Hemoglobin Variants And The A1C Test

The hemoglobin a1c test is a generally accurate way to assess a person’s average blood glucose level over the preceding three months and can help diagnose and monitor prediabetes and diabetes. however, certain health factors or conditions may cause a higher or lower hemoglobin a1c test result independent of diabetes. factors that can cause a. 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.. The a1c test, also known as an hba1c, hemoglobin a1c, glycated hemoglobin, or glycosylated hemoglobin test, is a blood test used to diagnose and monitor diabetes. it shows your average blood sugar levels for the past two to three months..

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.. Samples containing hemoglobin variants s and c may produce up to a 40% elevation of the expected hba1c value in this assay. samples containing > 10% of hemoglobin f may yield a lower than expected result with this test. hba1c results obtained by this test method for blood. A hemoglobinopathy is an inherited blood disorder in which there is an abnormal form of hemoglobin (variant) or decreased production of hemoglobin (thalassemia).a hemoglobinopathy evaluation is a group of tests that determines the presence and relative amounts of abnormal forms of hemoglobin in order to screen for and/or diagnose a hemoglobin disorder..

Glycated hemoglobin (glycohemoglobin, hemoglobin a1c, hba1c, less commonly hba 1c, hgba1c, hb1c, etc., also a1c informally with patients) 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.. 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 presence of hemoglobin variants can interfere with the measurement of hemoglobin a1c (hba1c). the advantage of using ion exchange chromatography methods is most variants that would affect hba1c results can be detected from analysis of the chromatogram so inaccurate results are less likely to be reported..
