Epstein-Barr Virus Nuclear Antigen (EBNA) Antibody (IgG) details
What Epstein-Barr Virus Nuclear Antigen (EBNA) Antibody (IgG) shows
This antibody targets the Epstein-Barr virus (EBV) nuclear antigen, and it's notable for appearing later than other EBV antibodies — typically not until 6 weeks to several months after infection — and then persisting for life. Because of this delayed appearance, a positive nuclear antigen antibody essentially rules out a very recent infection, making it a useful piece of the puzzle (alongside VCA IgG/IgM and early antigen antibodies) for determining whether an EBV infection is truly recent, ongoing, or well in the past.
Tests that include Epstein-Barr Virus Nuclear Antigen (EBNA) Antibody (IgG)
Epstein-Barr Nuclear Antigen (EBNA) IgG Antibodies typically appear several months after initial infection with Epstein-Barr virus (EBV). Their presence indicates past infection and helps differentiate between acute and prior EBV exposure.
- 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 Nuclear Antigen (EBNA) IgG Antibodies typically appear several months after initial infection with Epstein-Barr virus (EBV). Their presence indicates past infection and helps differentiate between acute and prior EBV exposure.
- 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.
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.
This test is used to detect infections caused by the Epstein-Barr virus (EBV), which is known for causing infectious mononucleosis, often referred to as mono. While mono is generally a mild illness in children and young adults, EBV can also lead to more serious conditions, including certain types of tumors.
- 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.
