I don't see anyone stepping up to diagnose this stuff, as it would be pretty hard from these pictures.
However, even if it is a parasite, it is obviously not protozoa whatever it is, so what good would a flight to NYC and a mucous swab do?"
Well, you already diagnosed it by telling this person that "it is not protozoa." You already made a judgment. You do not know that. The point is pictures cannot help one make such judgments, and better avoid them.
What good would do, a diagnosis? Well, Cahill will find it and give the proper meds. and cured. Would that not be good? To know what one has and get rid of it properly?
This is no some simple mucus swab. It finds what no other stool test can find, and this doctor does this test that no other doctor does. he finds not just protozoa, but others as well.
