Frequently Asked Questions
What does EBV Antibody Panel 2 test for?
It detects antibodies against four EBV antigens — VCA-IgM, VCA-IgG, EBNA-IgG, and EA-IgG — to determine the stage of Epstein-Barr virus infection.
Is fasting required for this test?
No, fasting is not required for EBV antibody testing. Sample can be collected at any time of day.
How long does it take to get results?
Reports are available within 24 hours as a verified PDF via www.drpatholab.in or WhatsApp/Email.
What do positive VCA-IgM and negative EBNA mean?
This pattern indicates acute primary EBV infection, commonly causing infectious mononucleosis, as EBNA antibodies appear weeks to months after initial infection.
Can this panel distinguish between past and current infection?
Yes. VCA-IgM positive with EBNA negative suggests acute infection, while VCA-IgG positive with EBNA positive indicates past resolved infection.
Does stress affect EBV antibody results?
No, stress does not alter EBV antibody levels. However, stress can trigger EBV reactivation in susceptible individuals, which may be reflected in EA-IgG positivity.
