What is the purpose of this test?
An Epstein-Barr Virus Nuclear Antigen (EBNA) Antibody Blood Test, IgG, is a blood test that helps doctors check for antibodies produced by our body's immune system in response to the Epstein-Barr virus. The Epstein-Barr virus is a common virus that can cause infectious mononucleosis, also known as mono. This blood test can help confirm whether a person has been infected with the Epstein-Barr virus in the past, as well as provide information about the stage of the infection.
The test helps diagnose if someone has had a recent or past Epstein-Barr virus infection. If the test shows the presence of IgG antibodies, it means that the person has been infected with the virus in the past and is now immune to it. This information can be important for patients with symptoms that may be linked to the Epstein-Barr virus or for those who may have been exposed to the virus.
Who would benefit from this test?
The EBNA Antibody Blood Test, IgG would be beneficial to:
- Individuals experiencing symptoms such as fatigue, swollen lymph nodes, or sore throat, which could be indicative of Epstein-Barr virus (EBV) infection
- People with a suspected past EBV infection who want to confirm their immunity status
- Patients with weakened immune systems who may be at higher risk for complications from EBV infection
When should I take an EBNA Antibody Blood Test, IgG?
The EBNA Antibody Blood Test, IgG, is typically taken to diagnose or rule out infectious mononucleosis. Symptoms that may prompt a doctor to order this test include:
- Fatigue
- Sore throat
- Fever
- Swollen lymph nodes
