A member asked:

I had mono when i was 13-24 and i am 35 now. ive suffered from chronic fatigue syndrome for the majority of my life. i recently had a vca igg test and the results were 480, is it true that anything above 320 means the virus is reactivated?

VCA IgM and EBV + PCR are proof of reactivated EBV, not the VCG IgG titer by my knowledge. By UPTODATE, regarding chronic fatigue syndrome and EBV infection: "most studies have found higher levels of certain antibodies to EBV antigens in patients with CFS compared with matched healthy control subjects. However, that does not prove a causal relationship." Take care.
