Epstein-Barr Virus Viral Capsid Antigen IgM

About

The Epstein-Barr Virus (EBV) is a member of the herpes virus family that causes glandular fever. Once infected, EBV remains in the body for the rest of the individuals life, but the virus often presents no symptoms unless the immune system is compromised which allows the virus to reactivate. Spread through the saliva, it is estimated that around 95% of people in the UK will have been infected by EBV by the time they are 40.

What might a low result mean?

A negative EBV VCA (IgM) antibody result partnered with a positive EBV Early Ag ab (IgG) result shows it is likely that you had a previous EBV infection.

What might a high result mean?

A positive EBV VCA (IgM) antibody result indicates that it is likely that you have a current or had a recent, EBV infection. If you also have a positive EBV Early Ag ab (IgG) result, then it is highly likely that you have had a previous EBV infection.
