DNA stool test A DNA stool test screens stool for DNA mutations, indicating the presence of precancerous polyps or colon cancer"

* Pros: No dietary changes are required before the test. There’s no need to empty the colon ahead of time. Stool sample collection can be done at home.

* Cons: The test currently screens for a limited number of DNA mutations in stool. The test hasn’t been universally accepted as a screening tool for colon cancer. False-negative results are possible.
