IgG Antibodies usually develop 2-4 weeks after initial infection and remain in the body for the life of the person. A positive results for this test typically indicates a previous exposure to EBV.

Tests for Epstein-Barr virus (EBV) antibodies are used to help diagnose infectious mononucleosis (mono) if a person is symptomatic but has a negative mono test.

EBV is a member of the herpesvirus family and is one of the most common human viruses. The virus occurs worldwide, and most people become infected with EBV sometime during their lives. In the United States, as many as 95% of adults between 35 and 40 years of age have been infected. Transmission of EBV requires contact with the saliva of an infected person. The incubation period, or the time from infection to appearance of symptoms, ranges from 4 to 6 weeks.
