The stool DNA test is a noninvasive laboratory test that identifies DNA changes in the cells of a stool sample. The stool DNA test specifically looks for DNA alterations associated with colon polyps and colon cancer.

The major goal of the stool DNA test is to detect whether DNA changes that indicate colon cancer or precancerous polyps are present in the colon.

The stool DNA test isn't currently available in the United States. Based on findings in clinical trials, an advisory committee of the Food and Drug Administration (FDA) recommended approval of the test. Should the full FDA grant approval, the stool DNA test could become an option for colon cancer screening.
