Log10-transformed quantitative viral load agreement for all samples determined by both the Galileo Pathogen Solution (GPS) and real-time quantitative PCR (qPCR) assays. The linear regression line was calculated as follows: y = 0.58x + 1.60 and R2 = 0.46. The Bland–Altman plot showed a mean difference of 0.91 log10 copies/mL or IU/mL. A: Linear regression plot for all samples. B: Bland–Altman plot for all samples. B19, parvovirus B19; BKV, BK virus; CMV, cytomegalovirus; EBV, Epstein–Barr virus; HHV, human herpesvirus; HSV, human herpesvirus; JCV, JC virus; VZV, varicella zoster virus; Diff, difference.
