Epstein-Barr Virus (EBV) Antibodies to Viral Capsid Antigen (VCA), IgG Labcorp test 096230

This test measures IgG antibodies to the Epstein-Barr virus (EBV), which are proteins your immune system creates after being exposed to the virus. Because these antibodies typically remain in your body for life, the test helps show whether you have had a past infection, such as mononucleosis (mono).
