This study compared EBV quantification for the kPCR PLX EBV DNA (kPCR; Siemens, France) and the EBV R-gene (R-gene; Argene, Biomerieux, France) assays and their correlation with the World Health Organization (WHO) standard. Methodology. WHO International Standard for EBV (WHO standard) dilution panels in different matrices were submitted to nucleic acid extraction with Versant kPCR Molecular Systems SP followed by the kPCR assay, or to nucleic acid extraction with the MagNA Pure LC System or NucliSENS easyMag followed by the R-gene assay. Seventy-four clinical specimens were tested in both assays. Bland–Altman analysis and linear regression analysis were performed. Results. The correlation between the WHO standard diluted in different matrices and the R-gene and kPCR assays was good (R2 >0.96 and R2 >0.92, respectively). A matrix effect was observed. The correlation of quantitative results between both assays yielded a coefficient of determination R2 higher than 0.74. The quantification differences were within one log10 of the averaged results for 34 of the 38 specimens (89 %). Calibration to the WHO standard did not increase the comparability of quantitative results. Conclusions. The quantitative results of both assays showed reasonable correlation with each other and a good correlation with the WHO standard.Lire moins >
