Thalassemia StripAssays® The easy way to optimize thalassemia screening using established innovations in diagnostics Thalassemia Assays Key to efficient screening Thalassemias are a major public health problem, particularly in Mediterranean countries, the Middle East, Asia, India and parts of Africa. For the large majority of affected individuals there is only supportive management but no ultimate cure. Health authorities therefore focus on prevention programs based on carrier and premarital screening. Since only a few α- and β-globin alleles are prevalent in each at-risk population, large-scale screening programs are feasible but require simple and automated test procedures. In healthy adults 97-98% of total hemoglobin (Hb) is HbA, consisting of two α-globin and two β-globin olypeptides (α 2β2). p Abnormalities in the structure and synthesis of both globin chains lead to an imbalance causing the two main types of halassemia: t α-thalassemia and β-thalassemia. The loss of one of the two α-globin alleles (-α) on chromosome 16 causes α+-thalassemia, whereas α 0-thalassemia is due to i nactivation of both α-globin alleles (--). Two groups of β-globin mutations are distinguished, depending on whether they lead to a reduction (β +) or an absence (β 0) of β-globin synthesis. In many regions, α- and β-thalassemia coexist with a variety of d ifferent structural Hb variants. These complex interactions give rise to an extremely wide spectrum of clinical phenotypes. urthermore, F an inherited increase of γ-globin expression in patients can artially p compensate for the lack of normal β-globin chain ynthesis in s β-thalassemia as well as sickle cell disease and thereby can a meliorate the clinical phenotype of both disorders.
