EBV EA-D IgG Interpretation:

≤0.8 AI                   NEGATIVE              

Absence of detectable EA IgG antibodies. A negative result generally excludes exposure to Epstein-Barr virus, but may also be associated with past 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.

0.9-1.0 AI               EQUIVOCAL          

A second sample should be collected and retested no less than one to two weeks later.

≥1.1 AI                   POSITIVE               

Presence of detectable EA IgG antibodies.  A positive result indicates exposure to Epstein-Barr virus and is usually associated with active or recent primary (acute) EBV infection or reactivation, but may also be observed in patients with no detectable evidence of recent infection.
