Why don't you just do Cologuard? I've had 2 colonoscopy's. Last year my doctor ordered the Cologuard for me. You do your duty in a little plastic toilet, use a little dipstick to get a stool sample, place that in a container and ship it off. My insurance took care of it, but my doctor told me (6 years ago) that it would cost $200 if my insurance wouldn't cover it.
