Specimen Collection Manual and Test Catalog
EBV NUCLEAR ANTIGEN IGG ANTIBODY
Geisinger Epic Procedure Code: LAB2232 Geisinger Epic ID: 7431Serum
0.5 mL serum; minimum 0.2 mL
Allow to clot. Centrifuge and submit 0.5 mL serum.
Refrigerated (preferred). Room temperature (stable 8 hours) or frozen specimen also acceptable.
Room temperature: 8 hours. 2-8°C: 96 hours. Frozen: 6 months
Specimen stability exceeded; specimen grossly hemolyzed.
| 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. |

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.
