Thank you very much for you reply. Any suggestions on how to ask my Dr. for this test because I feel she's not going to want to test me for that. I don't want to bring up parasites because I'm afraid she going to give the same answer a lot of us get where they don't believe us. I brought it up once and she said that doesn't happen where we live. Should I tell her I saw them in my stool? Any advice would be greatly appreciated.
