Interpretive Data
POSSIBLE RESULTS
VCA IgM | VCA IgG | EA IgG | EBNA IgG | Interprettion |
---|---|---|---|---|
- | - | - | - | No previous exposure |
+ | + | ± | - | Acute |
± | + | ± | ± | Recent* |
- | + | - | + | Past infection |
± | + | + | + | Reactivation |
- if only VCA IgG is positive, results indicate infection with EBV at some time;
however, the time of the infection cannot be predicted (ie, recent or past) since
antibodies to EBNA usually develop after primary infection (recent) or, alternatively,
approximately 5% to 10% of patients with EBV never develop antibodies to EBNA (past).
