Hemoglobinopathies and thalassemia are hereditary disorders of hemoglobin (Hb) affecting mankind at prevalent regional level. Automated cation exchange high performance liquid chromatography is being increasingly used as the initial diagnostic method for identifying normal and abnormal hemoglobin variants. Methodology: Total 2035 sample received and studied. All samples run on cation exchange high performance liquid chromatography machine by BIO-RAD. Results: Total 386(18.96%) cases had

Sickle cell trait (heterozygous Hb S) cases were 96(4.71%). Double heterozygous for sickle cell-beta thalassemia cases were 14(0.68%). There were 06 cases (0.29%) of Hb D heterozygous. There were one each case of Hb E heterozygous and Hb E-beta thalassemia (0.04% each). Hb F was raised in 7 adult cases (0.34%). Conclusion: To conclude, cation exchange high performance liquid chromatography is less time consuming, cost effective, labor saving, reproducible, accurate, sensitive and specific method to detect hemoglobinopathies and thalassemia. Most of the abnormal cases are diagnosed with this method, with few inconclusive cases require further genetic and molecular workup.
