Epstein-Barr Virus Nuclear Antigen (EBNA) Antibody (IgG)
Marks past EBV infection, the timing clue that separates old exposure from a recent one.
Consider this test if:
- Lingering fatigue, sore throat, or swollen glands and you want to know whether EBV is old or recent
- A positive EBV screen and you need to establish whether the infection is past or active
- Confirming prior EBV exposure as part of a broader workup
- Sorting recent mononucleosis from a long-resolved infection alongside VCA antibodies
- HSA/FSA eligible
- Results delivered to your dashboard · Reviewed by a real clinician
- Drawn at a CLIA/CAP-accredited lab near you ·
Pre-test considerations
No fasting required, and timing during the day does not matter. Because EBNA IgG appears only months after infection, testing too early in an illness can read negative even with active EBV; interpret it against VCA IgM and IgG and your symptom timeline.

What this test is for
Epstein-Barr virus is the cause of infectious mononucleosis and is carried for life by most adults. EBNA IgG antibodies appear during convalescence, typically 3 to 4 months after the initial infection, and then stay detectable for life, so a positive result indicates a past, resolved EBV infection rather than a new one. This timing is what makes EBNA useful: a positive VCA IgM with no EBNA IgG points to a recent or active infection, while a positive EBNA IgG suggests the infection happened months or years ago. It is most informative read alongside VCA IgG and VCA IgM, which is why EBV is often ordered as a full antibody panel when the question is the stage of infection.
This single EBNA IgG test answers one specific question, whether you have been infected with EBV in the past. If you are trying to date a current illness or sort recent from old infection, the broader EBV antibody panel (EBNA plus VCA IgG and IgM) gives the full picture in one draw.

Frequently asked questions
View all FAQsHow does pricing work?
Every test shows the member price next to the standard non-member price, so you can see what membership saves you. The member price is our cost, covering the lab and what it takes to run the service. It is never a profit on the test itself. Mito makes its money on the $9 membership, not on marking up your tests. Membership is $9 per month, and any applicable lab order or draw fee is itemized before you pay.
Where do I get tested?
Choose an available partner lab at checkout. If your cart contains multiple blood tests, Mito helps consolidate the eligible tests at one lab when possible. At-home kits and scans follow the collection or appointment process shown on their product page.
Is this eligible for HSA/FSA?
Yes. Eligible tests can be paid for with an HSA or FSA card at checkout.
When will I get my results?
Your results appear in your Mito dashboard after the laboratory completes processing. A clinician then reviews them before your analysis and personalized action plan are finalized. Timing varies by test, and specialty assays and at-home kits may take longer.
Do I need a physician's order?
No. Mito provides the laboratory order when one is required, so you do not need to arrange a separate physician visit before purchasing.
