Hemoglobin Variants And The A1C Test

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. the d-100 hemoglobin a1c (hba1c. The purpose of the ngsp is to standardize hemoglobin a1c test results to those of the diabetes control and complications trial (dcct) and united kingdom prospective diabetes study (ukpds) which established the direct relationships between hba1c levels and outcome risks in patients with diabetes.. Hemoglobin a1c (hba1c, or sometimes just called an a1c) is a way to assess your average blood glucose levels. mediterranean, or southeast asian descent may have hemoglobin variants that influence the accuracy of hba1c. 19 other variants are found in individuals from other parts of the world. some laboratories take hemoglobin variants into.

The most common variants worldwide are hemoglobin s and hemoglobin c. overestimation or underestimation of a1c for many hemoglobin variants will differ depending on both the type of method and the specific assay used. evaluation of an over-the-counter glycated hemoglobin (a1c) test kit. j diabetes sci technol. 2010; 4 (6):1495–1503. doi. Blakney g, higgins tn, holmes dj. comparison of hemoglobin a1c results by two different methods on patients with structural hemoglobin variants. clin biochem 1998;31:619-26. roberts wl, mccraw m, cook cb. effects of sickle cell trait and hemoglobin c on determinations of hba1c by immunoassay method. diabetes care 1998;21:983-6.. When your doctor says you have prediabetes or type 2 diabetes, it’s usually because of your a1c test result. if your a1c is over 5.7 but below 6.4, you like have prediabetes. if it’s over 6.5 on two or more tests, you likely have type 2 diabetes. you will get a glucometer with your first prescription of test strips and fingersticks..

Globin gene mutations affecting hemoglobin (hb), the major blood oxygen (o 2) carrier, are common, affecting an estimated 7% of the world’s population (weatherall and clegg 2001; kohne 2011).these mutations are broadly subdivided into those that impair globin protein subunit production (thalassemias) and those that produce structurally abnormal globin proteins (hb variants).. A hemoglobin test measures the amount of hemoglobin (hb or hgb) in your blood. this protein in your red blood cells (rbcs) carries oxygen and carbon dioxide between the lungs and the rest of the body. an altered hemoglobin level is often a sign of disease. without the right amount, your body may not have enough energy to function optimally.. Depending on the machine, a single a1c test can have up to a 0.5% margin of error, which means the “true” value might be 0.5% higher or lower than the measured a1c. for example, if a lab report shows an a1c value of 7.0%, the actual a1c value might range from 6.5% and 7.5%..
