Evaluation of the automated COBAS AMPLICOR hepatitis C virus PCR system

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

To evaluate the reliability and feasibility of the automated Roche COBAS AMPLICOR PCR system for routine detection of hepatitis C virus (HCV) RNA, a total of 405 serum samples previously tested by an in-house nested PCR and manual Roche AMPLICOR microwell plate HCV test were examined. Complete concordance was found between the results with the HCV COBAS AMPLICOR system and the previously determ...

Hepatitis C Virus Tests of AMPLICOR and COBAS AMPLICOR Prospective Multicenter Clinical Evaluation

Prospective multicenter clinical evaluation of AMPLICOR and COBAS AMPLICOR hepatitis C virus tests.

We conducted a multicenter clinical evaluation of the second versions of the manual AMPLICOR and the semiautomated COBAS AMPLICOR tests for hepatitis C virus (HCV) RNA (Roche Molecular Systems, Inc., Pleasanton, Calif.). The performance characteristics of these HCV RNA tests for diagnosis of active viral infection were determined by comparison to anti-HCV serological test results, alanine amino...

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...
