Is standard antibody testing for viruses such as Coxsackie too insensitive to be of any use in guiding treatment? The reason I am curious is because I know Dr Chia analyzes tissue from stomach biopsies. I was reading about one poster here, CBS, whose SIBO/dysbiosis improved when they went on Equilibrant. I did test negative for all viruses -- other than the chickenpox virus, which I had as a kid -- via standard lab testing here in Australia. One of my concerns in all of this is that I am fixating on the attendant issues, such as Candida, gut dysbiosis etc. in the hope that they might be the cause of my CFS, whereas I have no idea if I should be looking further into a governing problem like a virus. I'll bring it up with my doctor, but I don't get to see her for another 4 weeks. One doctor I saw did offer more sensitive antibody testing for viruses overseas, but I couldn't afford the cost unfortunately.
