How do heinz bodies form
WebIn newborns, there is an excess production of γ globin chains. These γ globin chains tend to also form tetramers and result in Hemoglobin Barts (Hb Barts). Hb Barts has a high oxygen affinity and is inefficient for oxygen delivery to the tissues of the developing fetus. In the silent carrier state, there is only a small amount of Hb Barts produced. WebStaining studies suggested that Heinz bodies are protein in nature and derived from hemoglobin. These observations were taken to indicate that Heinz bodies probably result from the direct effect of certain drugs on intra-erythrocytic hemoglobin.
