Stool Occult Blood Tests
Genetic Stool Test (FIT DNA Test)
The FIT-DNA test uses a combination of a test for genetic material (DNA) associated with colorectal cancer and the fecal immunological test ( Fecal Immunochemical Test (FIT) ). People collect stool samples for this test by using a kit at home and mailing the samples to the laboratory. If this test is abnormal, further tests are needed to determine the source. This test requires no dietary, medication, or vitamin restrictions. This test is more accurate than the fecal immunological test alone and is done every 3 years in people for whom screening is recommended. However, the FIT-DNA test is very expensive.
