Centrifuge. Transfer cell-free serum to plastic vial. Refrigerate.
Transport specimen to the laboratory. Transport with coolant pack if coming from clinic location.
Grossly hemolyzed/ lipemic, heat-treated serum, microbially contaminated and serum containing heavily-visible particulate.
|Negative:||No detectable IgG antibodies to EBNA-1. Patient is presumed to have no current or previous infecton with EBV and is susceptible to a primary infection.|
|Equivocal:||Immune status cannot be determined.|
|Positive:||Reactive for IgG antibodies to EBNA-1 indicating a past EBV infection.|
All equivocal test results will be repeated within two working days.
Patients with severe immunocompomised conditions may show negative results for EBNA antibodies even if antibodies to VCA are present. Likewise, an anti-EBNA response may fail to develop in patients who have an immunodeficiency disease or who are immunosuppressed.
This assay detects antibody to the EBNA-1 antigen and no other EBNA antigens.
The numeric value (OD Ratio) obtained for a reactive specimen is not indicative of the amount of antibody present and cannot be correlated to an antibody titer.
