Hemoglobin (Hb) disorders are among the most important hereditary diseases both in our country and in the world. Hemoglobins which result from amino acid change in the structure of globin chains are called abnormal hemoglobins or simply “Hb variants”. Following the protein level analysis methods for the determination of the presence of abnormal hemoglobins, the diagnosis is carried out by gene-level analysis. Our purpose for this review is to bring together and present all hemoglobin variant analysis methods.
