I have a friend who I know is suffering from parasites. She suffers from daily sever diarrhea, hernstomach gurgles lodly all the time, she has lost a ton of weight without trying, etc. Problem is, as we all know, doctor's aren't worth sh!t when it comes to getting them to test you, let alone treat you. Is there some kit she could order herself and send in a stool and/or saliva sample and get the results herself? I'm thinking if she were to go in with definitive results, they may take her seriously for once. Oh, and she's had a ton of G.I. tests, endoscopes, etc. but can't find anything wrong. Thanks.
