Do you know if it was PCR test you did? because since metametrix merged with Genova it is now microscopy and not PCR for checking for parasites.
Also I agree doctors are ignorant on this and some may even sugges is psychological which makes them even more idiotic. I even went to a parisitology center in Quebec drove hours to go there and the doctor gives me one blood test for strongyloides actually and a stool test which is mostly microscopy so it's an unreliable test.
It's amazing that so called parisitologist doctors don't know how to diagnose this stuff and make up excuses about having to travel to certain countries to get certain types of parasites. It's total bs.
The doctor in St. Louis doesn't bother doing traditional parasite testing in his office because of how unreliable the testing is. I think he may able to help with strongyloides. He uses a combo of meds, herbs and remedies.
