title: Enzyme-linked immunosorbent/chemiluminescence assays, recombinant immunoblot assays and nucleic acid tests in the diagnosis of HCV infection.
abstract: The diagnosis of hepatitis C virus (HCV) infection is defined according to the results obtained from screening assays, and confirmation made by supplemental tests, in order to exclude the possibility of false-positive and false-negative results and, therefore, a misdiagnosis. Identifying the patient's true clinical status is of crucial importance to direct an accurate course of therapy, but, often, the definition of this status is only possible after conjunctions and analysis of the results obtained from each methodology applied, considering the limitations of each assay. In this manuscript, it is discussed briefly the possible results obtained from the three methods most commonly applied in routine laboratory and their contribution in the diagnosis of HCV infection.
