Fecal immunochemical testing (FIT) is a non-invasive diagnostic procedure that looks for blood clots in the stool, which may indicate colorectal cancer or other diseases early on:

What it checks for

The test checks the lower intestines for signs of human blood. Hemorrhoids, polyps, ulcers, and colorectal cancer can all be indicated by blood in the stool.

How it works

An antibody that binds to the blood protein hemoglobin is used in the test.

How to perform the test

You place a small sample of stool in a collection tube or on a card. 

Accuracy

FIT is more accurate and has fewer false positive results than other tests because food and medicines don't interfere with it. 

When to get tested

You can get a FIT from your family doctor or nurse practitioner. You can also get a FIT at health care system contacts, such as flu vaccination clinics. 

After the test

You can resume normal activities immediately. Most FIT kits require you to send the sample to a laboratory or your doctor for analysis. 

Other names

FIT is also known as iFOBT, Immunoassay fecal occult blood test, Immunochemical fecal occult blood test, and Immunologic fecal occult blood test.
