In Professor Jose Montoya's study on ME/CFS patients, when the testing is performed using the EBV test from Quest Diagnostics, he considers an EBV-EA of
1:160 or more and an EBV-VCA IgG
1:640 or more to be high.

Note that:
EA = early antigen
VCA = virus capsid antigen (also denoted by CA)
EBNA = Epstein-Barr nuclear antigen
I am not sure how to translate this to the Labcorp figures. EBV antivirals such as Valtrex or Famvir at a dose of 1,000 mg four times daily can improve ME/CFS symptoms, but it takes around 2 years before the benefits appear, according to Dr A Martin Lerner's
research.
In Dr Lerner's study on 142 ME/CFS patients with herpes virus infections, 75% of patients responded to the appropriate antiviral treatment (Valtrex/Famvir for EBV, and/or Valcyte for HHV-6 and cytomegalovirus); the average improvement in ME/CFS symptoms was a 2-point increase on the
Energy Index Point Score scale (for example, as a result of antiviral treatment, an average patient may go from from level 4 to level 6 on this scale).
