N2 - We sought to determine the sensitivity and specificity of immunohistochemistry using the TORDJI-22 MoAb (BioGenex, San Ramon, Calif), which is specific for the C-100 protein of the hepatitis C virus, compared with reverse transcriptase-polymerase chain reaction (RT-PCR) of tissue for vital RNA. RT-PCR had been performed on 52 fixed tissue specimens. Immunohistochemistry was performed using prediluted antibody with the alkaline phosphatase/fast red (BioGenex) technique. Predigestion with Protease XXIV (BioGenex) and other procedures followed the manufacturer's protocols. Positive immunohistochemistry was narrowly defined as tightly clumped, perinuclear red granules in hepatocytes. Of the specimens, 28 were positive by RT-PCR. With RT-PCR as the standard of comparison, immunohistochemistry yielded a sensitivity of 70% and specificity of 84%. Positive cells, when present, were usually very rare. With stringent criteria, immunohistochemistry with the TORDJI-22 monoclonal antibody is a very specific, fairly sensitive diagnostic test for hepatitis C virus in fixed liver tissues.
