Kinetics of HBV DNA levels measured in patients' plasma specimens with the Aptima HBV Quant (red lines and filled circles) and CAP/CTM HBV 2.0 assays (black lines and filled circles) (A) or the Abbott RealTime HBV assay (black lines and filled circles) (B). The red or black dashed lines correspond to the LODs of the Aptima HBV Quant (1.0 log IU/ml) and CAP/CTM HBV 2.0 (1.3 log IU/ml) assays or the Abbott RealTime HBV assay (1.0 log IU/ml), respectively. HBV DNA levels are shown on the y axis. Red or black asterisks represent detectable but not quantifiable HBV DNA in the Aptima HBV Quant and CAP/CTM HBV 2.0 assays or the Abbott RealTime HBV assay, respectively. gA, genotype A; gB, genotype B; gD, genotype D; gE, genotype E; LAM, lamivudine; ETV, entecavir; ADV, adefovir; TDF, tenofovir.
