WebBesides, HbF could help to prevent complications occurring as a result of the sickling phenomenon of altered hemoglobin, successive vaso-occlusion, and abnormal blood viscosity. 42, 43 The main therapeutic effects of hydroxyurea on morbidity and mortality of patients with SCD are believed to be exerted through its enhancing effect on the level ... Fetal hemoglobin, or foetal haemoglobin (also hemoglobin F, HbF, or α2γ2) is the main oxygen carrier protein in the human fetus. Hemoglobin F is found in fetal red blood cells, and is involved in transporting oxygen from the mother's bloodstream to organs and tissues in the fetus. It is produced at around 6 weeks of pregnancy and the levels remain high after birth until the baby is roughly 2–…
