Epstein-Barr Virus Early Antigen (EA) Antibody (IgG) details
What Epstein-Barr Virus Early Antigen (EA) Antibody (IgG) shows
This antibody rises during active or very recent Epstein-Barr virus (EBV) infection and then typically fades over the following months, unlike VCA IgG or EBV nuclear antigen antibodies, which persist for life. Because of this pattern, early antigen antibodies are useful for helping pinpoint how recently an EBV infection occurred, which can be helpful when the timing of a mono-like illness is unclear or when unusual, prolonged, or reactivated EBV-related symptoms are being evaluated.
Tests that include Epstein-Barr Virus Early Antigen (EA) Antibody (IgG)
Epstein-Barr Early Antigen (EA) IgG Antibodies indicate active or reactivated Epstein-Barr virus (EBV) infection. Elevated levels can suggest ongoing viral replication or reactivation in the body.
- Epstein-Barr Virus Early Antigen (EA) Antibody (IgG) An antibody that rises during active or recent Epstein-Barr virus infection and typically fades over time, helping pinpoint how recent an infection is.
Epstein-Barr Early Antigen (EA) IgG Antibodies indicate active or reactivated Epstein-Barr virus (EBV) infection. Elevated levels can suggest ongoing viral replication or reactivation in the body.
- Epstein-Barr Virus Early Antigen (EA) Antibody (IgG) An antibody that rises during active or recent Epstein-Barr virus infection and typically fades over time, helping pinpoint how recent an infection is.
The Epstein-Barr Evaluation assesses several antibodies to the Epstein-Barr virus (EBV). It is performed to confirm active, past, or indeterminate infection for EBV-associated infectious mononucleosis.
- Epstein-Barr Virus Early Antigen (EA) Antibody (IgG) An antibody that rises during active or recent Epstein-Barr virus infection and typically fades over time, helping pinpoint how recent an infection is.
- Epstein-Barr Virus Nuclear Antigen (EBNA) Antibody (IgG) An antibody that appears months after Epstein-Barr virus infection and persists for life — its presence indicates a past, not recent, infection.
- Epstein-Barr Virus Viral Capsid Antigen (VCA) Antibody (IgG) An antibody indicating past infection with Epstein-Barr virus (the cause of mono); usually stays positive for life.
- Epstein-Barr Virus Viral Capsid Antigen (VCA) Antibody (IgM) An antibody that appears early in Epstein-Barr virus infection, helping identify a recent or current case of mono.
