Epstein-barr virus VCA IgM and EBNA IgG antibodies titered by immunofluorescence in microplates. A semi-automated method based on microtiter system.

We describe methods of immunofluorescence in microplates for titration of EBV VCA-IgM and EBNA-IgG antibodies and compare the sensitivity of the methods with glass slides and with microplates, showing the reproducibility of the methods. Results of VCA-IgM and -IgG, EA and EBNA titers obtained in four groups of patients are given, comprising cases of infectious mononucleosis, renal graft recipients, lymphoproliferative diseases and controls.
