What does my EBV IgG mean?
EBV-VCA IgG/IgM (viral capsid antigen): A positive IgG means you’ve had or currently have the infection; A positive IgM means the virus has been reactivated. EBV-EBNA IgG (nuclear antigen): A positive test result is usually associated with past infections. If playback doesn't begin shortly, try restarting your device.
What is EBV antigen?
Epstein-Barr virus ( EBV) antigen is an antigen associated with the Epstein-Barr virus. There are a number of EBV antigens associated with different stages of latency and infection. Laboratory testing can be used to look for specific antibodies to these antigens to screen someone for a history of infection…
What does a positive VZV IgG antibody detected mean?
VZV IgG testing is useful for the determination of an individual’s immune status and/or to aid in the diagnosis of varicella zoster infection. A positive VZV IgG result indicates the presence of antibodies to varicella zoster virus. The test cannot distinguish between past infection and current infection though, so a positive result could indicate active infection and not immunity.
What is EBV early antigen Ab IgG?
The EBV Early Antigen (EA) Antibodies IgG test looks for a type of antibody which the body typically develops in response to Epstein-Barr Virus . These antibodies usually develop in the acute phase of infection and fall below detectable levels after 3-6 months.

The virus can spread during the incubation period (amount of time when someone has exposure to the virus to when they experience symptoms), which is between four to six weeks. The virus spreads easily through saliva (spit) but can spread through other body fluids.
What Does It Mean If you Test Positive For Epstein Barr?
What does it mean if you test positive for Epstein-Barr? This is a common question when reviewing lab results with patients. Patients see that their results show positive next to some of their results. Naturally, they want to know what that means.
Testing Positive for Epstein Barr with Early Antigen D
The above video also shows another sample result of this early antigen D test. This test helps us differentiate when someone has a reactivation of the Epstein-Barr virus. We wouldn't look at this one to see if someone has a recent acute infection, however.
What is the interpretation of EBV?
The interpretation of EBV antibody tests requires familiarity with these tests and access to the patient’s clinical information. Interpretation of EBV antibody tests and diagnosis of EBV infection is summarized as follows: People are considered susceptible to EBV infection if they do not have antibodies to the VCA.
What is EBV testing?
Laboratory Testing. Epstein-Barr virus (EBV), also known as human herpesvirus 4, is a gamma herpes virus that occurs only in humans.

To test for EBV-specific antibodies, you will need to get your blood drawn. Results usually take a few days to come back.
What percentage of people tested have antibodies?
About 70% of people tested will have antibodies indicative of past infections [ 9 ]. After your body successfully fights the virus, it remains dormant in your cells and doesn’t cause any symptoms. However, it can be reactivated by stress or a weakened immune system [ 10 ].

It can also be important to rule out EBV infection and to look for other causes of the symptoms. Those with strep throat, an infection caused by group A streptococcus, for instance, need to be identified and treated with antibiotics.
How to diagnose mono?
Diagnosis of mono: People with mono are typically diagnosed by their symptoms and the findings from a complete blood count (CBC) and a mono test (which tests for a heterophile antibody).

VCA IgM antibodies occur at the beginning of the disease but decrease or even disappear within a few months. The presence of VCA IgM and VCA IgG without EBNA-1 IgG indicates acute infection, whereas the presence of VCA IgG and EBNA-1 IgG without VCA IgM is typical of past infection.
