This study was conducted on 100 children with β -thalassemia major aged between 1-15 years being regularly transfused at Department of Pediatrics, M.G.M. Medical College, after taking the consent from the parents and explaining them the purpose and method of study. Result: Mean serum values of ferritin, SGOT, SGPT was found to be 6416.9 ± 1581.8 µg/l, 205.4 ± 46.3 u/l and 254.6 ± 71.7 u/l in patients who received more than 100 transfusions while it was 3784.2 ±1304 µg/l, 104.9 ± 52.9 u/l, and 131.5 ± 63.6 u/l respectively for those who receive more than 100 transfusions. Conclusion: Youngsters with >100 transfusions had serum values of liver enzymes and iron overload higher when contrasted with those with <100 transfusions. The distinction in values between the two gatherings was seen as exceptionally huge (p esteem <0.001) Mean serum estimations of ferritin, SGOT, SGPT was seen as 6416.9 ± 1581.8 µg/l, 205.4 ± 46.3 u/l and 254.6 ± 71.7 u/l in patients who got in excess of 100 transfusions while it was 3784.2 ±1304 µg/l, 104.9 ± 52.9 u/l, and 131.5 ± 63.6 u/l individually for the individuals who get less than 100 transfusions.
