Clinical Utility

Used in the diagnosis of beta thalassemia sickling disorders, common structural hemoglobinapthies such as Hb S, C, E, D-Punjab, Lepore etc. It is also used in evaluating infants following abnormal newborn screening. Some forms of alpha-thalassemias are readily identified by HPLC e.g. when Hb Barts, Hb H, and/or Hb Constant Spring are observed. However, alpha-thalassemias resulting from only 1 or 2 alpha-globin gene deletion/nonfunction are not recognized in adults. Fortunately the majority (approximately 85-90%) of alpha thalassemia carriers have commonly encountered deletions which are identified in Alpha Thalassemia DNA Mutation Analysis. Rarer forms of alpha thalassemia (point mutations and small insertion/deletions) can be detected by Alpha-Globin Complete.
