Range Interpretation  

< 0.8 AI

 Negative A result of ≤ 0.8 AI for any of the three EBV markers indicates no detectable IgG antibody to that particular marker and should be reported as non-reactive for IgG antibody to that marker. If all three markers are negative and exposure to Epstein-Barr virus is suspected, a second sample should be collected and tested no less than one to two weeks later.
0.9 - 1.1 AI Equivocal Specimens with results in the equivocal range (0.9 to 1.0 AI) for any of the three markers should be tested by an alternate serologic procedure. Alternatively, a second freshly collected sample should be obtained and tested.

> 1.1 AI

 Positive A result of ≥ 1.1 AI for any of the three EBV markers indicates that the specimen is positive for IgG antibody to that marker. A positive test result presumes a current or past infection with EBV, and should be reported as reactive for IgG antibody to the marker(s). Other EBV serology assays
such as the EBV VCA IgM should be performed to confirm serological status, active acute, past or indeterminate infection for EBV-associated infectious mononucleosis.
