Clinical Significance
Primary infection by EBV causes infectious mononucleosis, usually a self-limiting disease in children and young adults. Infection with EBV can cause lymphoproliferative disorders including tumors. IgG recognizing Early Antigen D typically appears within a month after clinical presentation and is transient, lasting only 3-4 months. Persistently elevated levels suggest reactivation or persistence of EBV infection.
