Abstract:
Ninety-six samples from hepatitis B virus (HBV)-infected individuals were used to compare ViveST samples to frozen samples in COBAS TaqMan, RealArt, and VERSANT. Correlation (r) between ViveST samples and frozen samples was 0.99 in all three platforms. Correlations among tests using frozen samples were 0.96 for COBAS and RealArt, 0.94 for COBAS and VERSANT, and 0.97 for VERSANT and RealArt. The results indicate that ViveST may be useful in clinical practice. Different HBV-VL platforms correlated well with one another.
