The fecal immunochemical test (FIT) is a screening test for colon cancer. It tests for hidden blood in the stool, which can be an early sign of cancer. FIT only detects human blood from the lower intestines. Medicines and food do not interfere with the test. So it tends to be more accurate and have fewer false positive results than other tests.
You will be given the test to use at home. Be sure to follow the instructions provided.

Why the Test is Performed

Blood in the stool may be an early sign of colon cancer. This test is performed to detect blood in the stool that you cannot see. This type of screening can detect problems that can be treated before cancer develops or spreads.
