Epstein Barr Virus VCA IgG
What is EBV VCA IgG?
The Epstein Barr Virus Viral Capsid Antigen (EBV-VCA) Antibody IgG Test is a clinical test performed to diagnose an infectious mononucleosis disease, and to differentiate between an EBV infection and others when similar symptoms appear.
Why is EBV VCA IgG done?
The EBV-VCA test is performed when symptoms of mononucleosis appear without a positive mononucleosis test, including:
• Sore throat
• Swollen lymph glands
The test is also performed in pregnant women showing symptoms similar to flu.
Interpreting EBV VCA IgG results
A positive result in the VCA IgG test indicates a currently ongoing or a recent EBV infection.
