What is a high VCA IgG level?
What is a high VCA IgG level?
What does it mean if your EBV Ab VCA, IgG result is too high? Presence of detectable VCA IgI antibodies. A positive result indicates current or past exposure. The EBV-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.
What does EBV VCA IgG detected mean?
If you have antibodies to both VCA and EBNA, it means you’ve had an infection in the past. It could have been months or years ago. Most adults have these antibodies, because over 90% of adults have been infected with EBV at some point.
How do you read EBV results?
Interpretation of EBV Antibody Tests
- Susceptibility to infection. People are considered susceptible to EBV infection if they do not have antibodies to the VCA.
- Primary (new or recent) infection. People are considered to have a primary EBV infection if they have anti-VCA IgM but do not have antibody to EBNA.
- Past infection.
What is EBV-VCA IgG?

What is the difference between EBV and VCA blood tests?
EBV stands for Epstein-Barr virus. Epstein-Barr virus is a virus that typically causes a mild to moderate illness. Blood tests for Epstein-Barr virus detect antibodies to EBV in the blood and help establish a diagnosis of EBV infection. VCA stands for Viral capsid antigen.
When does anti VCA IgG peak in Epstein-Barr virus?
– Anti-VCA IgG appears in the acute phase of EBV infection, peaks at two to four weeks after onset, declines slightly then persists for the rest of a person’s life. More details on the infection? Epstein-Barr virus causes an infection that is very common.
What is anti anti VCA IgG?
Anti-VCA IgG appears in the acute phase of EBV infection, peaks at two to four weeks after onset, declines slightly then persists for the rest of a person’s life. what is EBV capsid IgG? The test has 3 components: viral capsid antigen (VCA) IgG, VCA IgM, and Epstein-Barr nuclear antigen (EBNA).
