EBV Panel

Specialist

also epstein-barr virus serology

What it isA panel of antibodies against Epstein-Barr virus, the ubiquitous herpesvirus that causes mononucleosis and persists lifelong after primary infection. VCA-IgM marks acute infection, VCA-IgG marks past or current infection, EBNA-IgG marks remote past infection.

DoesDistinguishes acute from past EBV infection and helps investigate suspected reactivation in unexplained fatigue or lymphadenopathy.

GoodA pattern of EBNA-IgG positive with negative VCA-IgM indicates resolved past infection — the expected state in most adults.

BadActive VCA-IgM positivity confirms recent or current acute infection. Persistently elevated early antigen antibodies may reflect chronic active EBV, which is rare but linked to certain lymphoid cancers and post-viral syndromes.

Standard

EBNA-IgG positive in most adults indicates past infection.

Optimal

EBNA-IgG positive, VCA-IgM negative (narrow target)

Modifiers

Over 90% of adults are EBV-positive by midlife; reactivation rises with immunosuppression and severe stress.

How to optimize

Lifestyle: Sleep, stress reduction, and limiting overtraining lower the chance of viral reactivation.
Diet: Whole-food anti-inflammatory pattern.
Supplements: Vitamin D3, zinc, vitamin C, monolaurin and lysine are popular adjuncts though evidence is modest.
Peptides: Thymosin Alpha-1, Thymalin for immune modulation in suspected reactivation states.
Drugs: No standard antiviral indicated for routine EBV; valacyclovir or ganciclovir occasionally used in severe reactivation.
