What is this test?
➤ The fecal immunochemical test (FIT) looks for hidden blood in the stool. This test is most commonly used to screen for colorectal cancer, but it can find gastrointestinal bleeding caused by other conditions. FIT uses a stool sample collected at home. While the FIT generally produces more reliable results than other stool-based tests, it cannot diagnose any condition. If abnormal results are found, more specialized testing may be needed.
➤ No special preparation needed.
