Abstract:
:The fluorescent antibody (FA) test for Epstein-Barr virus (EBV)-specific IgM antibody was improved by the use of sodium butyrate to induce a higher level of EBV antigen expression in P3HR-1 slide preparations and by removal of rheumatoid factor (RF) and IgG antibodies from test sera by means of adsorption with suspensions of Sepharose-IgG and Streptococcus pyogenes strain AR1. This method was compared with the Paul-Bunnell test (PB) on 1106 sera submitted to a routine virus diagnostic laboratory for infectious mononucleosis serology and 96.4% of sera showed concordant results. Thus the EBV-IgM-FA method was suitable for routine diagnostic use. However, it proved helpful to test EBV-IgM positive sera by PB to assist in the detection of cross-reacting IgM antibodies sometimes present.
