Abstract

Background: Hemoglobin is composed of globin polypeptide chains, which serve as immunogens to induce the production of antibodies.


Objectives: This review article aims to describe the use of antibodies against human hemoglobins for the identification of thalassemia and hemoglobinopathies.


Materials and methods: Literature review to discusses the nature of normal human hemoglobin, hemoglobin switching, thalassemia and hemoglobinopathies, laboratory diagnosis, general properties of antibodies, production of antibodies against human hemoglobins, and clinical applications of these antibodies in identifying thalassemia and hemoglobinopathies.Antibody-based detection of hemoglobin is highly useful in diagnosing thalassemia and hemoglobinopathies.


Results: Polyclonal antibodies against HbF have been applied in sandwich ELISA to accurately detect HbF levels. Monoclonal antibodies against HbH and Hb Bart’s have been produced and utilized in sandwich ELISA for detecting α-thalassemia. In addition, monoclonal antibodies against hemoglobin containing α-globin chains were developed and applied in sandwich ELISA to identify infants with Hb Bart’s hydrops fetalis, a condition in which no α-globin chains are produced. For detecting β-thalassemia carriers, monoclonal antibodies against HbA2 were produced, and sandwich ELISA was employed to measure HbA2 levels, which are elevated in these individuals.


Conclusion: Antibody-based diagnosis of thalassemia and hemoglobinopathies enhances the quality of screening platforms and makes diagnosis of these disorders more reliable.
