I've been told I had Lupus, MCTD and now I have blood test results. Could you help with understanding the results?
ebv ab vca, igg was 2214
wbv nuclear antigen ab, igg 607
I'm tired of all the run around and I want to feel better.
Hi ! Trying to interpret EBV test results is very confusing and I think most of it depends on the patient's symptoms. Here is what the CDC says about EBV testing.
What is WBV ? Do you mean EBV ? And what are your symptoms ????
SUMMARY OF INTERPRETATION
The diagnosis of EBV infection is summarized as follows:
If antibodies to the viral capsid antigen are not detected, the patient is susceptible to EBV infection.
Primary EBV infection is indicated if IgM antibody to the viral capsid antigen is present and antibody to EBV nuclear antigen, or EBNA, is absent. A rising or high IgG antibody to the viral capsid antigen and negative antibody to EBNA after at least 4 weeks of illness is also strongly suggestive of primary infection. In addition, 80% of patients with active EBV infection produce antibody to early antigen.
If antibodies to both the viral capsid antigen and EBNA are present, then past infection (from 4 to 6 months to years earlier) is indicated. Since 95% of adults have been infected with EBV, most adults will show antibodies to EBV from infection years earlier. High or elevated antibody levels may be present for years and are not diagnostic of recent infection.
In the presence of antibodies to EBNA, an elevation of antibodies to early antigen suggests reactivation. However, when EBV antibody to the early antigen test is present, this result does not automatically indicate that a patient's current medical condition is caused by EBV. A number of healthy people with no symptoms have antibodies to the EBV early antigen for years after their initial EBV infection. Many times reactivation occurs subclinically.
Chronic EBV Infection
Reliable laboratory evidence for continued active EBV infection is very seldom found in patients who have been ill for more than 4 months. When the illness lasts more than 6 months, it should be investigated to see if other causes of chronic illness or CFS are present.
