EBV Immunity IgG Test - EBV Viral Capsid Antigen (VCA) IgG Test

The Epstein-Barr virus (EBV) viral capsid antibody (VCA) test is a serological immunoassay that measures the level of immunoglobulin G antibodies directed against the viral capsid antigen (VCA) of the virus. This antibody appears early during acute infection and persists throughout life, making it an excellent indicator of prior viral exposure and the development of immunity.
