Hepatitis C virus (HCV) RNA quantification is extensively used for therapeutic management of HCV chronic infection (1). The COBAS HCV Monitor v2.0 assay (HCM) was until recently one of the most used quantification methods worldwide. Two of its drawbacks are the labor-intensive manual extraction of HCV RNA and the frequent requirement of serum dilution for accurate quantification (>5.7 log10 IU/ml) (4). The COBAS Ampliprep TNAI/COBAS TaqMan 48 Roche assay (CAPP-CTM) combines automated HCV RNA extraction with real-time PCR on the COBAS TaqMan 48 instrument (CTM48). It is one of the first platforms for clinical laboratories tending towards fully automated nucleic acid isolation and quantification, and it ensures a broad dynamic quantification range (43 to 69,000,000 IU/ml).
