Fig. 2.

Passing-Bablok regression (A, C) and Bland-Altman analysis (B, D) comparing HHV-6 DNA levels (log₁₀ copies/mL) between the Altona and reference qPCR methods in EDTA plasma. Panels A and B set the quantifiable ranges at 2.0 log₁₀ copies/mL for Altona and 2.7 log₁₀ copies/mL for the reference. Panels C and D set the quantifiable ranges at 3.0 log₁₀ copies/mL for both methods. Passing-Bablok: Solid line, regression line; dotted line, line of identity. Bland-Altman: Solid line, mean difference; dotted line, zero difference; dashed lines; 95% confidence intervals.
