Test Details


Use

Aid in the diagnosis of EBV infection (infectious mononucleosis) and EBV reactivation in conjunction with other serologic tests. The appearance of IgG antibodies to Early antigen-diffuse [EA(D)] is generally associated with the primary (acute) stage of EBV infection. For most individuals these antibodies are transient and are often undetectable after 6 months.
