Use. Guidelines for clinician who has prior knowledge of patient history and abnormal labs: • Hemolytic anemia, especially if accompanied by thrombocytopenia. • Anemia unresponsive to therapy; unexplained anemia. • Leukocyte/bone marrow disorder − pancytopenia, unexplained leukocytosis or leukopenia; leukemia. • Congenital disorders.The relationship is expressed in the following formula: eAG (mg/dL) = 28.7 x Hb A 1c (%) - 46.7. This relationship applies only to Hb A 1c methods certified as traceable to DCCT reference, and is based on overall averages and may vary slightly in individual patients. LabCorp uses a DCCT traceable method.The hemoglobinopathies are a complex group of inherited blood disorders in which one or more genetic abnormalities results in a change in the amount, structure, or function of one or more of the globin chains.
