A second-generation recombinant immunoblot assay (RIBA 2.0) is used in the United States to confirm infection with hepatitis C virus (HCV) in samples that are anti-HCV (enzyme immunoassay) positive. In some cases, indeterminate results of RIBA 2.0, which are defined as reactivity to a single antigen species or reactivity limited to two proteins derived from the same coding region of the HCV genome, are encountered.
