Preliminary identification of thalassaemia carriers is carried out by a screening program by full blood count (FBC) analysis as the baseline test to scrutinise the red blood cell indices, followed by morphologic examination of peripheral blood smears and subsequent confirmation by high-performance liquid chromatography (HPLC), haemoglobin (Hb) electrophoresis, and molecular genetics testing [4]. This evidence concerns the gene GSTM1 and thalassemia.
