WebFetal hemoglobin may be elevated in beta thalassemia, hereditary persistence of fetal hemoglobin (HPFH), and several hemoglobinopathies including sickle cell anemia. In heterozygous beta thalassemia, Hb F may be slightly increased to 2.1-5.0%, and in homozygous beta thalassemia is elevated to between 10 and 90%.
