EBV NA IgG Interpretation:

≤0.8 AI                   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.

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 EBNA IgG antibodies.  A positive result is indicative of past infection.
