Im considering making the trip.. its only 2 hours but what worries me about having a "sample" tested is that they aren't seeing the entire picture in just a sample. One day everything looks normal.. maybe 2 days. Then day 3 might produce a suspicious looking white things/pieces of rice... which i now think is unrelated to pinworms because the pinworms i saw moving and coiling up were tiny. Like a piece of embroidery thread... not as big as rice. and god knows what else ends up coming out. I'm afraid to go that route unless they would be willing to look at more than just a sample.
