Specimen Processing: Centrifuge.  Transfer cell-free serum to plastic vial.  Refrigerate.

Specimen Transport: Transport specimen to the laboratory. Transport with coolant pack if coming from satellite or outreach location.

Unacceptable Criteria: Grossly hemolyzed/lipemic, heat-treated serum, microbially contaminated and serum containing heavily-visible particulate.

Stability: Ambient: 8 hours
Refrigerated: 7 days
Frozen: 3 months at 20C or greater


Interpretation


Negative: No detectable IgG antibodies to EBV-VCA.  Patient is presumed to be non-immune and is susceptible to a primary infection.
Equivocal: Immune status cannot be determined.  If clinically warranted, a second sample should be taken 7 - 21 days after the first.
Positive: Reactive for IgG antibodies to EBV-VCA, indicating a current or past infection.  A positive IgG antibody level in the absence of current clinical symptoms indicates immunity to EBV-VCA.

 

All equivocal test results will be repeated within two working days.
