Evaluation of the COBAS TaqMan 48 real-time PCR system for quantitation of hepatitis B virus DNA.

چکیده
The purpose of this study is to evaluate the usefulness of the new real-time PCR COBAS TaqMan 48 analyzer, comparing it to the existing COBAS AMPLICOR HBV MONITOR based on conventional PCR technology. The study used 104 samples from different patients. No differences were found in the sensitivity of the tests. There was an excellent correlation between the sample with a viral load within the dynamic range of the two tests (r = 0.938). The COBAS TaqMan test has a wider linear range, and this fact enables quantifying of the viral load without diluting the sample.

BACKGROUND Diagnostic assays for the accurate quantitation of hepatitis B virus (HBV) DNA levels from patients undergoing antiviral therapy are useful for monitoring and tailoring therapy. Such assays should give accurate results with all HBV genotypes, including a seventh genotype of hepatitis B virus, genotype G, that has recently been identified in specimens from HBV-positive patients in the...
متن کاملDynamic comparison between Daan real-time PCR and Cobas TaqMan for quantification of HBV DNA levels in patients with CHB
BACKGROUND Hepatitis B virus (HBV) DNA levels are crucial for managing chronic hepatitis B (CHB). It was unclear whether Daan real-time polymerase chain reaction test (Daan test) or COBAS TaqMan HBV DNA Test (Cobas TaqMan) was superior in measuring different HBV DNA levels in clinical specimens. METHODS We enrolled 67 treatment-naïve, HBV surface antigen-positive CHB patients (high baseline v...

Hepatitis B virus (HBV) DNA quantification is used to establish the prognosis of chronic HBV-related liver disease, to identify those patients who need to be treated, and to monitor the virologic response and resistance to antiviral therapies. Real-time PCR-based assays are gradually replacing other technologies for routine quantification of HBV DNA in clinical practice. The goal of this study ...
