EBV protein antibody levels to gp350 (A), gH/gL (B), BHRF1 (C), BLRF2 (D), BFRF3 (E), and BMRF1 (F) in patients with HV, T-cell CAEBV without HVLPD, and healthy EBV-seropositive (EBV⁺) and EBV-seronegative (EBV⁻) blood-bank donors. Antibody levels were determined by immunoprecipitation and measured in light units.
