What does a positive EBNA mean?

The virus expresses nuclear antigen only when it becomes latent, and after that, the patient will be EBNA positive for the rest of his or her life. Therefore, a positive EBNA means that the patient does not currently have EBV mononucleosis.

What is a very high IgG?

IgG. High levels of IgG may mean a long-term (chronic) infection, such as HIV, is present. Levels of IgG also get higher in IgG multiple myeloma, long-term hepatitis, and multiple sclerosis (MS).

What is the treatment for high IgG levels?

Since hypergammaglobulinemia is caused by other conditions, there aren’t many direct treatment options available. But you can improve or cure this condition by treating other underlying infections, immune disorders, and diseases. One uncommon treatment for this condition is immunoglobulin replacement therapy.

Can a negative antibody test indicate infectious mononucleosis?

A positive result of a heterophile antibody test also is strong evidence in favor of a diagnosis of infectious mononucleosis. A negative result of an antibody test, particularly during the first week of illness, may indicate that the patient does not have infectious mononucleosis.

Are there any elevated anti EBNA-1 IgG ABS?

Interestingly, elevated anti-EBNA-1 IgG was found in a group of patients who had anti SSA/Ro antibodies. Anti-VCA IgM Abs were more frequently found in those patients with a very high titer of ANA (P=0.06); moreover detection of anti-VCA IgM/IgG in absence of anti-EBNA-1 IgG was more frequent in the patient than in the control group.

How is ESR used to diagnose EBV infectious mononucleosis?

An ESR is most useful in differentiating group A streptococcal pharyngitis from EBV infectious mononucleosis. The sedimentation rate is elevated in most patients with EBV infectious mononucleosis, but it is not elevated in group A streptococcal pharyngitis.

When does The monospot test become negative for EBV?

Sensitivity is 85%, and specificity is 100%. The heterophile antibody test (eg, the Monospot test) results may be negative early in the course of EBV infectious mononucleosis. Positivity increases during the first 6 weeks of the illness.
