In Australia you dont get a number or level of the antibodies just igm is a new infection and igg positive is an old infection. This also happens with other viruses and bacterial infections where i have seen other countries report the antibody number which can indicate if its a current ingection if high enough.
I dont think the powers above want us to know or they dont believe in chronic viruses unless you have hiv, hepatitis or on immunosuppressives for organ transplants. Its just insane.
I often wonder if people when first diagnosed with mono, they were put on antivirals for 2 weeks or so, not only do i think cfs would go down but quite possibly MS and many cancers related to ebv🤔
EBV diagnostics can be quite difficult. For example I have elevated IgM but Western Blot M is negative. EA is quite low and EBNA high. IgG is quite low (102). So I don't know what to make out of this lab results.
The problem with all those tests is that you need a properly working immune system which many ME patients don't have (immune exhaustion, Ig deficiency etc) or you test fluids via qPCR for viral copies and that possibly won't tell you anything with certainty bc EBV is a) neurotropic and b) can disappear from the blood completely (which leads to the AB testing problem, bc in the fluids the immune system is more robust and reacts more likely to pathogens)
What else can we do? Test for cytokines that are our defense mechanism for pathogens (interferons). For example elevated levels of EBI 2-mRNA are correlated to lytic EBV infections (in the upper normal for me). But unfortunately, pathogens can knockout IFNs as well so all in all you could have a persistent infection of EBV and without tissue and/or nerve biopsies won't know about it.
