Laboratory Diagnosis of Hemoglobinopathies and Thalassemia
Hemoglobinopathies and thalassemias are among the most common genetic diseases, with 7 percent of the world’s population carrying a hemoglobin mutation. Due to relatively recent migration, North American countries are now home to a large number of patients with thalassemia. Among these disorders, sickle cell syndromes and thalassemias constitute major public health problems.
Most laboratories use a combination of high-performance liquid chromatography (HPLC), capillary electrophoresis, molecular analysis, and mass spectrometry to diagnose thalassemias. Definite identification of hemoglobinopathies can be achieved by a stepwise alogrithmic approach that includes a detailed clinical history, HPLC, and molecular analysis. This presentation will review the pathophysiology, pertinent clinical and laboratory findings, and recent advances in the field.

Medical Director, Hematopathology and RBC Laboratory, ARUP Laboratories
Assistant Professor of Pathology, University of Utah School of Medicine
Dr. Agarwal is an assistant professor of pathology at the University of Utah School of Medicine. She received her MD at Delhi University in India and was a postdoctoral research scholar at the University of Iowa. She served as a pathology resident, a hematopathology fellow, and a molecular genetics pathology fellow at the University of Utah School of Medicine. Dr. Agarwal is board certified in hematopathology, anatomic pathology, and clinical pathology. She is also a member of several professional societies, including the College of American Pathologists, American Society for Clinical Pathology, and American Society of Hematology. Dr. Agarwal’s research interests include RBC disorders including hemoglobinopathies/thalassemias, hemolytic anemias and molecular diagnostics related to these disorders.
After this presentation, participants will be able to:
- Understand the pathophysiology of hemoglobinopathies and thalassemia.
- Recognize the most important expected test results in hemoglobinopathies and thalassemias.
- Be able to direct ordering physicians to appropriate tests for these disorders.
