Chronic Hepatitis B virus (HBV) infection is a major liver disease worldwide and its clinical manifestations are linked to immune response. The purpose of this study was to evaluate the relationship between selenium, copper, and zinc in comparison with transaminase level in chronic HBV patients. Serum samples of the HBV infected patients were obtained from Tooba medical center, Sari, Iran. Sixty patients were enrolled in this study (36 men and 24 women), mean age: 39.6 ± 12.2 years. The concentration of zinc, selenium, copper and transaminases were determined using an autoanalyzer system. Concentrations of selenium (0.273 ±0.056 μg/dl) and zinc (2.1±0.037) was elevated in patients with low transaminase levels as were significantly different in comparison with patients with high transaminase level (P
