For standardization of quantitative PCR (qPCR) detection of EBV viral genomes from participant plasma, a commercially available standard containing 5.59 × 108 EBV genome copies per ml (ATCC, VR-3247SD) was used. Serial log dilutions of this standard, ranging from 106 to 100 copies per ml, were made to establish the sensitivity of the TaqMan qPCR and included on each assay plate. The standard curve was created in the usual way by plotting the Ct values against the standard of known concentration. x–y scatter diagrams were drawn, and the correlation coefficient (r2) was determined. Linear regression analysis was performed using GraphPad Prism.
