Detect: Epstein-Barr Virus (EBV) Panel (Quest)

What this panel includes

• Epstein-Barr virus antibody panel: Measures viral capsid antigen (VCA) IgM and IgG along with EBNA IgG, helping distinguish a recent, past, or resolved infection

• Epstein-Barr virus early antigen D (EA-D) antibody: A marker associated with active or reactivated infection, useful for identifying ongoing viral activity beyond a past exposure

Biomarkers tested

Why patients choose this

• One draw that looks at both past exposure to and active or reactivated Epstein-Barr virus.
• Helpful for those exploring whether chronic or reactivated EBV activity may be playing a role in their symptoms.
• Appropriate for individuals experiencing unexplained or persistent fatigue, recurring flu-like symptoms, or brain fog.
• Antibody testing that helps distinguish a recent, past, or resolved infection from ongoing activity.
• Schedule your lab test seamlessly and complete it at a lab near you.

Before your test

Important information

Why it matters: most people are exposed to EBV and the virus typically becomes dormant, but in some cases it can reactivate and contribute to ongoing symptoms.

Who it's for: appropriate for those with unexplained or persistent fatigue, recurring flu-like symptoms, or brain fog, or anyone exploring whether chronic or reactivated EBV may be involved.
