Frequently Asked Questions
What does EBV Nuclear Antigen IgM indicate?
EBNA IgM antibodies appear early during acute Epstein-Barr Virus infection, typically within the first 2–4 weeks, and help confirm recent or active infectious mononucleosis.
Is fasting required for this test?
No, fasting is not required for EBV EBNA IgM testing. Sample can be collected at any time of day.
How is this test different from VCA IgM?
VCA IgM appears even earlier and is the primary screening marker for acute EBV, while EBNA IgM appears slightly later and provides additional confirmation of early-stage infection.
What sample is collected?
A 1 mL serum sample is collected via venipuncture from the arm vein.
When will the report be available?
Verified PDF report is available within 24 hours via www.drpatholab.in or WhatsApp/Email.
Can this test confirm past infection?
No, EBNA IgM indicates recent acute infection. Past or resolved EBV infection is better assessed using EBNA IgG and VCA IgG antibodies.
