Persist, I got results back today from ParaWellness and I have both giardia and cryptosporidium. You are 100% right. Yeast didn't show up this time, but it did the last test. I am treating for fungals, yet. I think it is protozoa that I feel crawling around. I go to St. Louis next week - if he doesn't tx, I believe my family doctor will. I'll bet there are some regular medications that will get these once I get the right dope. How are you doing??
