Epstein-Barr Virus Antibodies

Epstein-Barr Virus Antibodies Test | London Blood Tests

Test for Epstein-Barr Virus antibodies with our EBV blood test for £108. UKAS-accredited testing, fast results, optional GP consultation.

The Epstein-Barr Virus (EBV) Antibodies Test detects antibodies produced in response to EBV infection. It helps determine whether an infection is current, recent, past, or reactivated, and is commonly used to investigate glandular fever, chronic fatigue, and unexplained immune symptoms. Testing is performed in a UKAS-accredited laboratory, with an optional GP consultation available.

What is an Epstein-Barr Virus Antibodies Test?

The Epstein-Barr Virus is a common herpesvirus; most people are exposed at some point in their lives. After initial infection, EBV remains dormant in the body and may reactivate later, particularly during periods of immune stress.

The EBV Antibodies Test measures a panel of antibodies that reflect different stages of infection, typically including:

• VCA IgM – indicates recent or acute infection

• VCA IgG – indicates past exposure

• EBNA IgG – confirms previous infection and immune memory

By analysing these antibodies together, clinicians can determine whether symptoms are linked to acute infection, recent recovery, past exposure, or possible reactivation.

At London Blood Tests, EBV serology is analysed using validated immunoassays aligned with UK infectious disease standards.

Benefits of the EBV Antibodies Test

1. Identifies Current or Recent Infection
   Helps confirm acute EBV infection, including glandular fever.

2. Detects Past Exposure
   Determines whether you have previously been infected with EBV.

3. Assesses Possible Viral Reactivation
   Useful in patients with persistent fatigue or immune symptoms.

4. Supports Chronic Fatigue Investigation
   EBV reactivation may contribute to prolonged post-viral fatigue.

5. Differentiates EBV From Other Illnesses
   Helps rule out other causes of sore throat, lymphadenopathy, or malaise.

6. Informs Immune Health Assessment
   Provides insight into viral burden and immune system response.

7. Optional GP Consultation for Interpretation
   Results can be reviewed with a GP to guide management or further testing.

Why Do I Need an EBV Antibodies Blood Test?

You may benefit from an EBV Antibodies Test if you experience:

• Persistent or unexplained fatigue

• Swollen lymph nodes (neck, armpits, groin)

• Recurrent sore throat

• Fever or flu-like symptoms

• Brain fog or poor concentration

• Muscle aches or weakness

• Enlarged spleen or liver abnormalities

Testing is commonly recommended if you:

• Have suspected glandular fever

• Have prolonged fatigue after a viral illness

• Have immune suppression or chronic stress

• Need clarification of past EBV exposure

Because EBV symptoms overlap with many other conditions, antibody testing provides valuable diagnostic clarity.

Your EBV Antibodies Test Results – Explained

Results are reported as positive or negative for each antibody.

Typical interpretation:

• VCA IgM positive: current or recent EBV infection

• VCA IgG positive + EBNA IgG negative: recent infection

• VCA IgG positive + EBNA IgG positive: past infection

• All antibodies negative: no evidence of prior exposure

Important notes:

• Most adults show past infection

• Persistent symptoms with past infection may warrant further immune testing

• Results should be interpreted in the context of symptoms and clinical history
