IgM antibodies to VCA are normally present in acute IM and generally
absent in convalescence. The presence of antibodies in otherwise
healthy individuals usually indicates immunological exposure either
as silent primary infection or reactivation. Antibody levels tend to
rise and peak after 3-4 weeks, then decline and usually dissipate
after 2-3 months.
Antibody Index (AI) values reflect qualitative changes in antibody
concentration that cannot be directly associated with clinical
condition or disease state.
