How do you interpret Epstein-Barr results?

Interpretation of EBV Antibody Tests
  1. Susceptibility to infection. People are considered susceptible to EBV infection if they do not have antibodies to the VCA.
  2. Primary (new or recent) infection. People are considered to have a primary EBV infection if they have anti-VCA IgM but do not have antibody to EBNA. …
  3. Past infection.

What are normal EBV numbers?

Optimal Result: 0 – 17.9 U/mL. EBV-VCA, IgG is an antibody (protein) that is produced by the body in an immune response to an Epstein-Barr virus antigen. EBV stands for Epstein-Barr virus. Epstein-Barr virus is a virus that typically causes a mild to moderate illness.

How is EBV measured?

To measure EBV loads, real-time polymerase chain reaction (PCR) is a standard and widely-used method (8, 11). The real-time PCR method measures the accumulation of amplified products with a laser scanning in a closed tube or 96-well plate format (12).

What does it mean if your EBV is high?

Some types of EBV antibodies are present in higher numbers during an active infection. Other EBV antibodies mean that you had an infection in the past. Depending on the type of antibodies your test shows, your healthcare provider can find out more about what is causing your illness.

What does a high EBV early antigen AB IgG mean?

Presence of detectable EA IgG antibodies. A positive result indicates exposure to Epstein-Barr virus and is usually associated with active ore recent primary (actute) EBV infection or reactivation, but may also be observed in people with no detectable evidence of recent infection.

What does a high EBV early antigen D AB IgG mean?

Clinical Significance

IgG recognizing Early Antigen D typically appears within a month after clinical presentation and is transient, lasting only 3-4 months. Persistently elevated levels suggest reactivation or persistence of EBV infection.
