My doctor wants me to have a gastric biopsy to find traces of an enterovirus he suspects. I read a lot about people who had blood work done that found evidence of enterovirus or other infectious agents. I am wondering why would someone choose one method over the other ? Blood work seems a lot faster. But where can it be done, and what do you ask for ? I am getting impatient. I know there is no cure but there is a way to try sensible treatments if you know what you are fighting with. A gastric biopsy will take months to do and more months to get the results. I think my doc sends it to be analyzed somewhere in the US, maybe with Dr Chia even. If anyone can explain this for me, I will be really grateful.
