Interpretive Data
| Antibody | Timing of when the antibody is typically detected in the blood |
| Viral Capsid Antigen (VCA)-IgM antibody | Appears first after exposure to the virus and then tends to disappear after about 4 to 6 weeks |
| VCA-IgG antibody | Emerges during acute infection with the highest level at 2 to 4 weeks, then drops slightly, stabilizes, and is present for life |
| Early Antigen (EA-D) antibody | Appears during the acute infection phase and then tends to disappear; about 20% of those infected will continue to have detectable quantities for several years after the EBV infection has resolved. |
| Epstein-Barr Nuclear Antigen (EBNA) antibody | Does not usually appear until the acute infection has resolved; it develops about 2 to 4 months after the initial infection and is then is present for life. |
