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. Please refer to this interpretation chart:
Jul 12, 2023 · These are anti-VCA IgM and anti-VCA IgG. Anti-VCA IgM appears when you're first infected with EBV and usually disappears in 4 to 6 weeks. Anti-VCA IgG first appears in the acute...
Apr 10, 2024 · Viral capsid antigen (VCA) Anti-VCA IgM appears early in EBV infection and usually disappears within four to six weeks. Anti-VCA IgG appears in the acute phase of EBV infection, peaks at 2 to 4 weeks after onset, declines slightly then persists for the rest of a person's life.
Jul 2, 2018 · The presence of VCA IgG antibodies indicates that an EBV infection has occurred at some time recently or in the past. The presence of VCA IgM antibodies and the absence of antibodies to EBNA...
VCA IgG antibodies appear early in EBV infection and titers peak between 2-4 weeks after the appearance of symptoms. IgG levels decline slightly but persist for life. The presence of VCA IgG antibodies in healthy individuals indicates immunological exposure to EBV either as silent primary infection or past exposure.
Jun 10, 2019 · VCA stands for Viral capsid antigen. – Anti-VCA IgM appears early in EBV infection and usually disappears within four to six weeks. – 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.
The test has 3 components: viral capsid antigen (VCA) IgG, VCA IgM, and Epstein-Barr nuclear antigen (EBNA). Presence of VCA IgM antibodies indicates recent primary infection with Epstein-Barr virus (EBV). The presence of VCA IgG antibodies indicates infection sometime in the past.
In cases where EBV is suspected but the heterophile antibody is not detected, an evaluation of EBV-specific antibodies (eg, IgM and IgG antibodies to EBV viral capsid antigen [VCA]) and antibodies to EBV nuclear antigen (EBNA) may be useful.
The appearance of IgG antibodies to EA(D) is generally associated with the primary (acute) stage of EBV infection. For most individuals, EA(D) IgG antibodies are transient and are ogten undetectable after 6 months while VCA IgG antibodies persist indefinitely.
