Frequently Asked Questions
What does EBV EA IgM indicate?
EBV EA IgM is an antibody produced during the early phase of Epstein Barr Virus infection. It appears shortly after symptoms begin and helps confirm acute or recent EBV infection, commonly associated with infectious mononucleosis.
Is fasting required for this test?
No, fasting is not required for EBV EA IgM testing. Blood can be collected at any time of day without dietary restrictions.
How long does it take to get results?
Results are typically available within 24–48 hours. Verified PDF reports can be accessed via www.drpatholab.in or WhatsApp/Email.
What is the difference between EBV EA IgM and VCA IgM?
VCA IgM appears earliest and confirms acute infection, while EBV EA IgM appears slightly later during active viral replication. Both are used together for accurate diagnosis of recent EBV infection.
Can EBV EA IgM stay positive for a long time?
EBV EA IgM usually declines within weeks to a few months after acute infection. Persistent positivity may indicate reactivation of the virus and requires clinical correlation.
Who should get this test done?
Individuals presenting with fever, sore throat, swollen lymph nodes, fatigue, and splenomegaly suggestive of infectious mononucleosis should undergo EBV EA IgM testing along with VCA IgM and EBV nuclear antigen (EBNA) panels.
