title: Evaluation of three different assays for the assessment of Epstein Barr Virus immunological status.
abstract: Various attempts have been made to improve Epstein Barr Virus serodiagnosis by developing convenient methods. The present study evaluated the performance of multiplexed bead assays and immunoblot based assays on automated platforms by comparing them with immunofluorescence based assays for the determination of EBV immune status. A total of 45 serum samples were included in the study. Serum samples were tested by multiplexed bead EBV assays (AtheNA Multi-Lyte, Zeus Scientific,USA) and immunoblot based assays (Euroline, Euroimmun AG, Germany) on automated platforms. Assay systems were evaluated by comparing them with immunofluorescence based assays (Zeus Scientific, USA). For EBV anti-VCA IgM, anti-VCA IgG, anti-EA and anti-EBNA, the kappa values reflecting agreements of AtheNA and IFA were 0.20, 0.54, 0.92 and 0.95 for anti-EA, anti-VCA IgG, anti-VCA IgM and anti-EBNA respectively and the agreements of Euroline and IFA were 0.53, 0.67, 0.81 and 1.000 for anti-VCA IgG, anti-EA, anti-VCA IgM and anti-EBNA respectively. The results of the study performed on a limited number of serum samples demonstrated that the multiplexed bead assays and immunoblot assays agree with the standard IFA assay for anti-EBNA IgG and anti-VCA IgM detection while the agreement is less for anti-EA and anti-VCA IgG.
