Also worth noting dgr labs seems to be one of the better parasites tests out there if your doctor is willing to a good test. The corporate lab parasite stool tests are cap. If you get a diagnosis with them let us know but I haven't really heard of it happening yet.
The dgr test looks for DNA rather than microscopy so it has benefits over other stool tests if you carry something that it's test looks for. Also it is worth checking out Dr's reviews online before consulting with them but there seem to be a handful of U.S. doctors who treat parasites.
If you have any questions about the Dr's feel free to message me. I've seen a few of the top ones and I'm still working on getting better. It can cost a lot of money that is for sure.
