EBV-specific IgG in controls compared to BL patients. Plasma from BL patients (n = 32) and controls (n = 25) was diluted at 1:6400 and tested using a Luminex Bead Based array. Specific EBV antigens were (A) Zta-specific IgG, (B) EAd-specific IgG, (C) VCA-specific IgG, (D) EBNA1-specific IgG. The MFI of 75 of Luminex beads for each of the antigen tested is indicated on the y-axis. P values of Mann-Whitney U tests are indicated in the figures. Horizontal bars represent median values per each study population.
