Objectives: The plan of this current research was in the direction for towards theassessment of the existing ELISA (Enzyme Linked Immunosorbant Assay) method throughantibodies testing for identification of hepatitis C virus disease by comparing their outcome withthe Real Time polymerase chain reaction analysis. Setting: Peoples Medical College HospitalNawabshah. Period: December 2015 to December 2016. Methods: In this current research 100blood samples were analyzed due to the presence of anti-HCV antibodies by 3rd-generationenzyme-linked immunosorbent assay testing. All the specimens were 100% positive. Polymerasechain reaction test was performed according to the laboratory directions in anti- hepatitis C virusantibodies positive patients to validate the diagnosis of hepatitis C virus infectivity. Results: Thisresearch shows that, the entire results were positive by Enzyme Linked Immunosorbant Assaytesting. As compared with polymerase chain reaction the of Enzyme Linked ImmunosorbantAssay in this research the screening test for anti hepatitis C virus - antibodies is about 2%false positive. Out of the 100 samples 98 cases are positive by Real Time polymerase chainreaction analysis while only 02 cases report are negative (2%). Conclusion: The proportion ofhepatitis C virus infectivity was 100% by 3rd-generation enzyme-linked immunosorbent assaytesting, 98% by Real Time polymerase chain reaction analysis. As in our research the hepatitisC virus –Ribonucleic acid is present in 98% cases who are the Anti- hepatitis C virus antibodiespositive patients, it can be suggested that Anti-HCV antibodies detection by third generationELISA technique in routine procedure is sufficient to determine HCV infection.
