IgG antibodies to EA are frequently present in acute IM and generally
absent in convalescence. The presence of antibodies in otherwise
healthy individuals usually indicates reactivation, especially when
paired with rising Antibody titer to Nuclear Antigen. EA Antibody
levels tend to rise and peak after 3-4 weeks, then decline and
usually dissipate after 6 months. Antibody to Nuclear Antigen
usually persists for life.
 
Antibody Index (AI) values reflect qualitative changes in antibody
concentration that cannot be directly associated with clinical
condition or disease state.
