HbA 1c is a measure of the beta-Ndeoxy fructosyl component of hemoglobin. Relationships among insulin resistance, obesity, diagnosis of the metabolic syndrome and cardio-metabolic risk. This serves as an indicator that blood sugar is increasing and that action should be taken. Since these new RBCs will have only existed for a short vakores of time, their presence will lead HbA 1c to underestimate the actual average levels.
Hence, people with recent blood loss, hemolytic anemiaor genetic differences in the hemoglobin molecule hemoglobinopathy such as sickle-cell disease and other conditions, as well as those that have donated blood recently, are not suitable for this test.
