Bhargava et al.'s study reported mean Hb at 12g/dL and RBC count at 5.1 million/cu.mm while Jameel et al.'s findings showed a mean RBC count of 4.1 million/cu.mm and a mean RBC count was 4.1 million/cu.mm and Elshaikh RH et al. study in 2022 demonstrated a mean RBC count of 5.7 million/cu.mm and RDW 18.4% [18,19]. In comparing our findings with previous studies, it was evident that there were variations in hematological parameters among individuals with beta-thalassemia trait. This evidence concerns the gene GSTM1 and Beta-thalassemia.
