Evaluation of the Roche COBAS AmpliPrep/COBAS TaqMan HCV Test.
The performance of the Roche COBAS AmpliPrep/COBAS TaqMan HCV Test (CAP/CTM) was evaluated. The limit of detection was 9.5 IU/mL using the 3rd International Standard. Serial dilutions of each genotype demonstrated good reproducibility and linearity. Correlation with samples previously tested with the Roche Analyte Specific Reagent (ASR) was very good, with the CAP/CTM assay measuring 0.24 log I...
متن کاملClinical evaluation of the automated COBAS AMPLICOR HCV MONITOR test version 2.0 for quantifying serum hepatitis C virus RNA and comparison to the quantiplex HCV version 2.0 test.
A second-generation hepatitis C virus (HCV) quantitative assay (COBAS AMPLICOR HCV MONITOR Test, version 2.0; COBAS HCM-2) has been developed, with the intention of achieving equivalent quantification of all HCV genotypes and improving assay performance. To evaluate the clinical performance of COBAS HCM-2 and its utility in predicting the response to alpha interferon treatment, sera from 215 ch...
متن کاملAssessment of viral loads in patients with chronic hepatitis C with AMPLICOR HCV MONITOR version 1.0, COBAS HCV MONITOR version 2.0, and QUANTIPLEX HCV RNA version 2.0 assays.
The correlation between response to antiviral therapy and pretreatment viral load in patients with chronic hepatitis C has prompted the development of quantitative assays to measure viral load. The aim of our study was to assess the clinical relevance of the newly developed semiautomated PCR system COBAS HCV MONITOR version 2.0 in comparison with (i) the AMPLICOR HCV MONITOR version 1.0 assay, ...
متن کاملPerformance evaluation of the new Roche cobas AmpliPrep/cobas TaqMan HCV test, version 2.0, for detection and quantification of hepatitis C virus RNA.
To evaluate the analytical performance and explore the clinical applicability of the new Roche cobas AmpliPrep/cobas TaqMan HCV test, v2.0 (CAP/CTM v2.0), a platform comparison was performed on panels and diagnostic samples with the Roche cobas AmpliPrep/cobas TaqMan HCV test (CAP/CTM v1.0), the Siemens Versant HCV RNA 3.0 branched DNA (bDNA) test, the Abbott m2000 RealTime HCV assay (Realtime ...
متن کاملHCV RNA measurement in samples with diverse genotypes using versions 1 and 2 of the Roche COBAS® AmpliPrep/COBAS® TaqMan® HCV test.
BACKGROUND Accurate HCV RNA measurement is required for monitoring treatment. Underquantification has been reported with some genotypes, particularly genotype 4, using version 1 of the Roche COBAS(®) AmpliPrep/COBAS(®) TaqMan(®) HCV Test. OBJECTIVES Compare the viral loads of clinical specimens representing diverse genotypes from across the United States using versions 1 (V1) and 2 (V2) of th...
