TEST DETAILS
Interpretation guide:
Result
Interpretation
Negative Absence of detectable EBNA IgG antibodies. A negative result generally excludes past EBV infection. If exposure to Epstein-Barr virus is suspected despite a negative finding, a second sample should be collected and tested no less than one to two weeks later.
Equivocal Suggest a second sample be collected and tested one to two weeks later.
Positive Presence of detectable EBNA IgG antibodies. A positive result is indicative of past infection.
CPT code(s):

Synonyms:
EBNA, Epstein Barr IgG antibody to nuclear antigens
Epstein Barr Nuclear Antigen, Epstein Barr Virus
EBV-EBNA, EBNAAB, EBV Serology, EBNA, EBV Antibody
EBNA IgG Antibody, Epstein Barr Nuclear Antigen IgG
Clinical significance:
Epstein-Barr virus (EBV) is responsible for infectious mononucleosis (IM) and has also been implicated in Burkitt's lymphoma and nasopharyngeal carcinoma. EBV-NA (Epstein-Barr virus nuclear antigen) IgG antibodies appear during the convalescent phase of IM and remain present throughout life. A positive EBV-NA IgG antibody in a healthy individual indicates past immunological exposure to EBV.
