About the test
This test measures IgG to the VCA capsid antigen of Epstein–Barr virus (EBV). IgG to the capsid antigen appears after contact with EBV and usually persists for a long time; on its own it does not distinguish recent from previous infection. The test may complement investigation of suspected infectious mononucleosis or other clinically justified situations.
Interpretation considers the combination of VCA IgM, VCA IgG and EBNA IgG, the timing of symptoms and other information. A single elevated marker does not prove viral reactivation or automatically explain prolonged fatigue.
Why it is ordered
- Complement EBV serological testing.
- Clarify the nature of the immune response in combination with other antigens.
How to prepare
