Antibodies Epstein-Barr IgA (EBV-IgA), IgG (EBV-IgG), IgM (EBV-IgM)

Blood tests for Epstein-Barr virus (EBV) antibodies are used to help diagnose EBV infection, the most common cause of infectious mononucleosis (mono), if a person is symptomatic but has a negative mono test.

In pregnant women with symptoms of a viral illness, one or more EBV antibody tests may be ordered along with tests for cytomegalovirus (CMV), toxoplasmosis, and other infections to help distinguish between EBV and conditions that may cause similar symptoms.

These tests may be ordered for an asymptomatic person to see if that person has been previously exposed to EBV or is susceptible to a primary EBV infection. This is not routinely done, but it may be ordered when someone, such as an adolescent or an immunocompromised person, has been in close contact with a person who has mono.
