Fecal Immunochemical Test (FIT): About This Test
What is it?
This test checks for hidden blood in the stool. Your kit will explain how to collect a sample or test a small amount of stool. You'll return the kit to the doctor or to a lab. Or if your kit shows results at home and is positive for blood, call your doctor right away.
Why is this test done?
This test is done to check for colorectal cancer and colon polyps that can cause blood in the stools.
How is the test done?
It is important to follow the instructions provided with the FIT kit.
Here are some general instructions:
- Check the expiration date on the package. Don't use a test kit after its expiration date.
- Follow the instructions exactly. Do all the steps, in order, without skipping any of them.
- After you finish your test, follow the instructions that you were given for returning the test.
- You will have to repeat the FIT if the sample freezes, if it is stored somewhere too hot, or if it is not brought to the lab within 7 days after collecting it.
If your test shows that blood was found in your stool sample, you may need to have a colonoscopy. Talk with your doctor about having a colonoscopy if the FIT showed blood in your stool.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse advice line (811 in most provinces and territories) if you are having problems. It's also a good idea to keep a list of the medicines you take. Ask your doctor when you can expect to have your test results.
