Interpreting Hemoglobin (Hb) Electrophoresis by HPLC results


Interpretations

         All the results should be carefully interpreted in correlation with the patient's signs and symptoms and other laboratory findings. 

  • Presence of high level of sickle cell hemoglobin (HbS ) on HPLC denotes either sickle cell trait or sickle cell anemia 
  • Increased levels of fetal hemoglobin (HbF) on HPLC is associated with beta thalassemia major. Sometimes, it can also be seen in sickle cell anemia 
  • High HbA2 levels are mostly associated with beta thalassemia minor or trait. Recent studies say that HbA2 level between 4 to 9% is diagnostic of beta thalassemia trait 
  • Other less common hemoglobins which can be detected are hemoglobin D, J, G, M etc.
