that's why I think the whole viral testing bit isn't giving an accurate picture.
This is the problem scientists have in their efforts to link low-level pathogenic infections in the body to chronic disease conditions.
Merely testing the blood may not tell you much about low-level infections which might be hidden in the organs.
You may only be able to detect these low-level organ infection using an organ biopsy. That's possible for some organs, but you cannot really take brain biopsies from living patients. So neurological diseases like ME/CFS which may involve a brain infection are hard to study.
