types of stool tests
What type of stool test is used. There are several different types of stool tests. The type of stool test used depends on why the test is being done and what the doctor is looking for. Some types of stool tests are: 1  gFOBT (guaiac-based fecal occult blood test), which uses a chemical reaction on a paper card to find traces of blood in the stool that you canât see. 2  FIT (fecal immunochemical test), which uses specific antibodies for human blood to find traces of blood in the stool that you canât see.
