    <p>According to the routine assay for guidance of treatment response (Roche COBAS AmpliPrep/COBAS TaqMan HCV quantitative assay Version 1 (CAP/CTM Ver. 1) 13 patients underwent an abbreviated course of antiviral therapy (24 weeks). In comparison: number and therapy outcome of patients who would have been eligible for a shortening of antiviral treatment according to the results of the Roche COBAS AmpliPrep/COBAS TaqMan HCV quantitative assay Version 2 (CAP/CTM Ver. 2), according to the Abbott RealTime HCV assay (ART) and the adapted version of the ART Abbott RealTime HCV assay (column ART adapted: shortening of antiviral treatment also in cases where HCV RNA was detected but </p
