(A) Linear regression of HBV DNA levels measured by Alinity m HBV assay in 61 paired plasma and DBS specimens containing HBV genotype A (n = 10), B (n = 6), C (n = 1), D (n = 6), E (n = 33), or G (n = 1) or an unidentified genotype (4 cases). The red solid line represents the linear regression and the black dotted line represents the reference (i.e., no difference between plasma and DBS specimens). (B) Bland-Altman plot analysis of HBV DNA levels measured by the Alinity m HBV assay in 61 paired plasma and DBS specimens containing HBV genotype A (n = 10), B (n = 6), C (n = 1), D (n = 6), E (n = 33), or G (n = 1) or an unidentified genotype (4 cases). The black dotted and dashed lines represent deviation ± 1.96 SD, respectively.
