Evaluation of the automated COBAS AMPLICOR hepatitis C virus PCR system.

Performance of the COBAS AMPLICOR HCV MONITOR test, version 2.0, an automated reverse transcription-PCR quantitative system for hepatitis C virus load determination.

A clinical evaluation of an automated quantitative PCR assay, the COBAS AMPLICOR HCV MONITOR test, version 2.0 (v2.0), was carried out to assess the performance of this test in comparison with that of the previous, manual version, the AMPLICOR HCV MONITOR test, and with that of nested PCR. Serial dilutions of serum samples infected with genotype 1b, 2a, or 3, as well as synthetic RNA transcript...

Multicenter evaluation of the COBAS AMPLICOR HCV assay, an integrated PCR system for rapid detection of hepatitis C virus RNA in the diagnostic laboratory.

The benefits shown by the recent introduction of PCR for the in vitro diagnosis of hepatitis C virus (HCV) infection has prompted the development of standardized, ready-to-use assays that can be implemented in routine clinical laboratories. We have evaluated the clinical performance of COBAS AMPLICOR HCV (COBAS), the first instrument system that allows the automation of HCV RNA amplification an...

RNA in the Diagnostic Laboratory System for Rapid Detection of Hepatitis C Virus AMPLICOR HCV Assay, an Integrated PCR Multicenter Evaluation of the COBAS

Evaluation of an automated sample preparation protocol for quantitative detection of hepatitis C virus RNA.

The COBAS AMPLIPREP instrument for automated sample preparation has recently been introduced. In this study, the COBAS AMPLIPREP/COBAS AMPLICOR HCV MONITOR test, which includes this new molecular device, was evaluated and compared to the COBAS AMPLICOR HCV MONITOR test, which includes a manual extraction protocol. Interassay and intra-assay variation, precision, and linearity were determined, a...

Evaluation of the COBAS TaqMan HCV test with automated sample processing using the MagNA pure LC instrument.

The COBAS TaqMan HCV Test (TaqMan HCV; Roche Molecular Systems Inc., Branchburg, N.J.) for hepatitis C virus (HCV) performed on the COBAS TaqMan 48 Analyzer (Roche Molecular Systems) currently relies on a manual sample processing method. Implementation of an automated sample processing method would facilitate the clinical use of this test. In this study, we evaluated the performance characteris...
