HbH disease is classified as moderate to severe in alpha thalassemia. Due to the variety of genetic mutations, as explained previously, there is marked variation in phenotypic expression. Patients can be asymptomatic, have episodic anemia requiring transfusions, and even fatal hydrops fetalis in utero. Fairhurst, R. M.; Fujioka, H.; Hayton, K.; Collins, K. F.; Wellems, T. E. (2003). "Aberrant development of Plasmodium falciparum in hemoglobin CC red cells: implications for the malaria protective effect of the homozygous state". Blood. 101 (8): 3309–15. doi: 10.1182/blood-2002-10-3105. PMID 12480691. for anemia by a right shift in their oxygen dissociation curves, unlike those with many other forms of β-thalassemia intermedia De la Salle B. Pre- and postanalytical errors in haematology. Int J Lab Hematol. 2019;41(1):170-176. doi:10.1111/ijlh.13007 Spherocytosis: sphere-shaped RBCs found in hereditary spherocytosis or in autoimmune haemolytic anaemia.If a person’s levels fall below these thresholds, they have anemia. However, low hemoglobin alone does not always diagnose the cause of anemia. Haemoglobin F (foetal haemoglobin): makes up to 1%-2% of Hb found in adults; it has two alpha and two gamma protein chains. This is the primary haemoglobin produced by the foetus during pregnancy; its production usually falls shortly after birth and reaches adult levels by 1-2 years. As indicated by recent studies in Sri Lanka, the application of a clearly defined scoring system for severity combined with DNA analysis: These tests serve to help confirm mutations in the alpha and beta globin-producing genes. DNA testing is not a routine procedure but can be used tohelp diagnose thalassemia and to determine carrier status if needed. Nakamori E, Shigematsu K, Higashi M, Yamaura K. Postoperative noninvasive hemoglobin monitoring is useful to prevent unnoticed postoperative anemia and inappropriate blood transfusion in patients undergoing total hip or knee arthroplasty: A randomized controlled trial.

Chronic kidney disease: Decreased kidney function can mean that your body doesn’t make enough erythropoietin, a hormone necessary for red blood cell production. mild forms of thalassemia intermedia, not dissimilar to HbH disease (see Vichinsky 2012). Their interactions with HbE β thalassemia are more complex and clinically variable, and are discussed in more detail in and other signs of cirrhosis are very rare. Diabetes mellitus, secondary to iron deposition in the pancreas, frequently developsThis thalassemia syndrome is characterized by the presence of HbA, HbE, and Hb Bart’s, and results from the interaction of
