What it measures
- Heterophile antibodies — antibodies that can indicate a recent infection
- EBV viral capsid antigen (VCA) IgM — antibodies that suggest a recent Epstein-Barr virus infection
- EBV VCA IgG — antibodies that indicate a past or current Epstein-Barr virus infection
- EBV nuclear antigen (EBNA) — antibodies that typically appear later in an Epstein-Barr virus infection
