What is Epstein-Barr Virus Nuclear Antigen IgG (EBV NA IgG)?
This test detects IgG antibodies against the Epstein-Barr Virus (EBV) Nuclear Antigen. These antibodies typically develop several weeks to months after the initial infection and usually persist for life, indicating a past or latent EBV infection.
Why is this test important?
The presence of EBV NA IgG indicates a past EBV infection and immunity to the virus. It is crucial for differentiating between acute, recent, and past infections when interpreted alongside other EBV antibody tests, helping to establish the timing and stage of the infection.
