Log-log 10 graph showing the linear regression comparing VL data obtained from 47 matched samples of DBS vs. Plasma. Log10 measurements of the HBV DNA in DBS and Plasma samples, assessed by Cobas Monitor Amplicor. The values for the DBS are plotted against the values for the matched plasma samples. The linear correlation between the two samples is shown (R2 = 0.86). The Pearson correlation coefficient was 0.93.
