Description

The Epstein-Barr Virus (EBV) is a common human virus and the primary cause of infectious mononucleosis ("mono"). This blood test panel evaluates whether someone has a current, recent, or past EBV infection by measuring specific antibodies.

Panel Includes the Following Tests:

  • VCA IgM (Viral Capsid Antigen – IgM):
  • Appears early in infection
  • Disappears in 2–3 months
  • Indicates recent or acute infection
  • VCA IgG (Viral Capsid Antigen – IgG):
  • Appears during acute phase
  • Persists for life
  • Indicates past or current infection
  • EBNA IgG (Epstein-Barr Nuclear Antigen – IgG):
  • Appears 3–4 months after infection
  • Remains detectable for life
  • Indicates past infection

Why Get Tested?

  • Unexplained fatigue or sore throat
  • Swollen lymph nodes or spleen
  • Suspected mono in teens or young adults
  • Clarify past EBV exposure or immune status
