Just a little bit of coquille feedback. I went to my new primary physician and I asked him about cologuard. He said he was made aware of it by another patient who asked about it, the doctor then read up on it and cited the very good New England Journal of medicine article. He said that colonoscopy is still the gold standard, and that really there's very little uptake in the Doctor community that he is around. Interesting that he is only finding out about this from patient inquiries… That is both a positive and a negative in my opinion.
