Few studies have been done to examine zinc levels in thalassemia patients and its relationship with ferritin.Objective To compare serum zinc in thalassemia patients and healthy controls and to assess for a possible correlation between serum ferritin and zinc in thalassemia patients.Methods This cross-sectional study in 68 subjects was done from October 2016 to August 2017. Serum ferritin measured by chemiluminescence immunoassay and serum zinc by inductively coupled plasma mass  spectrometry (ICP-MS). Wilcoxon test was used to analyze for differences between serum zinc in thalassemia patients and controls. Spearman’s correlation test was used to analyze for a possible correlation between ferritin and serum zinc in thalassemia patients.Results There were 34 patients with thalassemia and 34 healthy control subjects. The median serum zinc was 119.34 µg/dL (IQR=71.27) in the thalassemia group and 120.08 µg/dL (IQR=26.28) in the control group (P=0.36). There was no significant correlation between serum ferritin and zinc in thalassemic children (r=-0.023; P=0.895).Conclusion There is no significant difference in serum zinc levels between thalassemic children and healthy controls. There is  no significant correlation between serum ferritin and zinc in thalassemic children. ER -
