HBsAg, anti-HBs serologic markers were tested by ELISA Immunoassay (ELISA), ELISA Roche Cobas E411 ELISA and AST ALT enzymes by Beckman Syncron LX20 autoanalyzer.HBsAg seropositivity rate was 14% and Anti-HBs seropositivity rate was 74%. HBsAg positivity was 14.28% in men and 13.51% in women. AST and ALT enzyme averages (47.2 IU / L and 49.7 IU / L) were found in 10 patients with HBsAg (+) group and significantly higher in the 10 healthy control group (25.4 IU / L, 27.6 IU / L) . HBV mark ratios in Tatvan are close to the region and country rates. In addition, AST and ALT liver enzymes were significantly higher in HBV cases. https://www.biotech-asia.org/vol16no2/investigation-of-blood-biochemical-values-of-hepatitis-b-seroprevelancia/ ALT; AST; Enzymes; HBV; Seroprevelance
