The Epstein-Barr Virus (EBV) Antibodies to Viral Capsid Antigen (VCA), IgG blood test is used to help diagnose EBV infection. This is the most common cause of infectious mononucleosis (mono), if a person is symptomatic but has a negative mono test. The EBV test may be ordered for an asymptomatic patient to see if that patient has been exposed to EBV or is at risk to a primary EBV infection.
