Experiencing fatigue, sore throat, or swollen lymph nodes? An Epstein-Barr Virus (EBV) Viral Capsid Antigen Test (IgG) can help determine if you’ve been previously exposed to EBV, the virus most commonly linked to infectious mononucleosis (mono).
This EBV blood test detects IgG antibodies specific to the viral capsid antigen, indicating a past EBV infection. While EBV often causes mono, it can also be associated with other long-term health conditions.
Discussing your EBV IgG test results with a healthcare provider ensures a proper evaluation and a clear understanding of your immune response especially if your symptoms persist or worsen.
