Epstein-Barr Virus Infection Diagnosis and Interpretation

Introduction to EBV IgG Results

• An EBV IgG level greater than 8.0 indicates past infection with Epstein-Barr virus, demonstrating that the individual has developed immunity to the virus following previous exposure 1
• A positive EBV IgG result (>8.0) without accompanying IgM antibodies generally indicates past infection rather than acute or recent infection 1

Diagnostic Context and Serologic Markers

• VCA IgM indicates recent or acute infection when positive 1
• The pattern of serological markers helps distinguish between primary acute infection: Positive VCA IgM, positive or negative VCA IgG, negative EBNA 1

Clinical Significance and Management

• Isolated elevated EBV IgG (>8.0) without clinical symptoms generally requires no treatment or further evaluation 1
• In cases of suspected chronic active EBV infection, additional testing beyond serology (including viral load measurement) is necessary 2, 3
