- The stool guaiac test, a common diagnostic screening for colon cancer.
- Tests for parasites, which usually enter the digestive tract as part of their life cycle
- A test for pH, which can indicate lactose intolerance or infection.
- A fecal fat test, which can show malabsorption of fat typical of steatorrhea
