It's a low specificity test. If you get a false positive you'll be getting a colonoscopy anyway, and (less of a risk, but still worth considering) if you get a false negative it's a bit of a problem. That's how my gastro explained it, and a bit of my own internet research supported.

How about DNA based stool tests instead of colonoscopy?

92% vs 99% specificity
Given effort and cost (10x lower) seems incredibly better option than colonoscopy.
