Epstein-Barr Virus Viral Capsid Antigen (VCA) Antibody (IgM) details
What Epstein-Barr Virus Viral Capsid Antigen (VCA) Antibody (IgM) shows
This antibody targets the viral capsid antigen (VCA) of Epstein-Barr virus, and unlike the IgG form, VCA IgM appears early in infection and then fades over the following weeks to months, making it a key marker for identifying a recent or currently active case of infectious mononucleosis ('mono'). It's typically checked alongside VCA IgG when mono is suspected, since a positive IgM together with a positive IgG suggests recent infection, while a positive IgG with negative IgM suggests past, resolved infection.
Tests that include Epstein-Barr Virus Viral Capsid Antigen (VCA) Antibody (IgM)
Epstein-Barr Viral Capsid Antigen (VCA) IgM Antibodies indicate recent or acute infection with Epstein-Barr virus (EBV). Detection of IgM antibodies helps diagnose active or primary EBV infections, such as infectious mononucleosis.
- 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.
Epstein-Barr Viral Capsid Antigen (VCA) IgM Antibodies indicate recent or acute infection with Epstein-Barr virus (EBV). Detection of IgM antibodies helps diagnose active or primary EBV infections, such as infectious mononucleosis.
- 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.
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.
