Yes, you are right, all the more so since my health deteriorated after a trip to Mexico. At the time, I was diagnosed with giardia and blastocystis hominis and took a course of metronidazole but I have always suspected there might be other parasites. After that, I had several st. analysis done, they all came back negative but these tests are crude.
So I just got the kit by Great Smokies Lab for yeast and parasites. I need to know for sure if I have candida and/or parasites.
