The Cobas Taqman assay for hepatitis B virus (HBV) DNA showed linear detection over 7 logs for genotypes A to D. The coefficient of variation was 1.2% at
1,000 IU/ml and 22.0% at 10 IU/ml. In 97 clinical samples, the log HBV DNA/ml differed by 0.11 between Cobas Amplicor and Cobas Taqman (r2 = 0.97).
