Reference Values
Epstein-Barr Virus VIRAL CAPSID ANTIGEN (VCA) IgM ANTIBODY:
Negative
Epstein-Barr Virus VIRAL CAPSID ANTIGEN (VCA) IgG ANTIBODY:
Negative
EPSTEIN-BARR VIRUS NUCLEAR ANTIGEN (EBNA) IgG ANTIBODY:
Negative
Interpretation
The profile has 3 components: viral capsid antigen (VCA) IgG, VCA IgM, and Epstein-Barr nuclear antigen (EBNA).
Presence of VCA IgM antibodies suggests an acute or recent primary infection with Epstein-Barr virus (EBV).
Presence of VCA IgG antibodies indicates infection sometime in the recent or remote past.
Antibodies to EBNA develop 6 to 8 weeks after primary infection and are detectable for life.
Refer to table below for interpretation of EBV antibody results.

Negative |
Results suggest recent EBV infection. The detection of only anti-VCA IgG should be interpreted with caution in immunocompromised patients, as this population may demonstrate diminishing or undetectable levels of anti-EBNA IgG antibodies. |
