Testing of stool, or feces, can be helpful when monitoring disease activity in Crohn’s disease and IBD. These tests can indicate if inflammation or internal bleeding is present and assist your healthcare team with disease management and treatment decisions.
Doctors will typically order blood and stool sample testing before deciding to book invasive procedures such as capsule and upper endoscopies and colonoscopies.
Your healthcare provider will order one of two types of stool tests: fecal occult blood and fecal calprotectin.
You will be given a container, gloves, and a “hat” to enable you to collect a sample at home. When collected, samples are usually returned to your doctor’s clinic before being sent to a laboratory for testing.
When you’re collecting your sample, avoid touching the inside of the container or blowing air into it, as this can add bacteria to the sample and cause false results.
The fecal occult blood test
A sample for a fecal occult blood test is taken on a single day or over multiple days, depending on your doctor’s request. Occult blood exists in tiny amounts that are detected by chemicals used in this test. Positive results indicate the presence of occult blood, but not the location of the bleeding.
The fecal calprotectin test
Fecal calprotectin tests are useful when diagnosing and monitoring inflammation in IBD and Crohn’s disease. High levels of this protein can suggest an IBD diagnosis. When used in disease management, a positive test result can indicate a flare.
It is important to note that no test is 100 percent accurate. No single test, whether blood, imaging, or stool, can diagnose IBD, but each test may be used to assist in the diagnostic process.
If you’ve ever wondered whether you should contact your doctor, do it. It is better to ask for advice or seek reassurance from your doctor than suffer alone.
Each person’s disease is unique to them, and not everyone has the same manifestations or symptoms. My experiences may be different than yours, but you can never be too prepared. For me, it could be worse.
