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).
