Why This Test Is Done

Your healthcare provider may order this test if you’ve had symptoms like persistent diarrhea, abdominal pain, or unexplained weight loss. It’s also used to monitor IBD activity or check for complications after a colonoscopy. The test looks for substances in your stool that indicate inflammation, which can help guide treatment decisions.

What to Expect Before the Test

No special preparation is needed beyond what your provider instructs. You may be asked to avoid certain foods or medications for a day or two before your colonoscopy. Follow your provider’s instructions carefully to ensure accurate results.

What the Test Involves

During or shortly after your colonoscopy, a small sample of your stool will be collected. This sample is then analyzed for specific markers that indicate inflammation, such as white blood cells or proteins released during an immune response. The test is typically done in a lab and results are ready within a few days.

What the Results Mean

If the test shows signs of inflammation, it may suggest an active IBD or another inflammatory condition. If results are negative, it means no obvious inflammation was detected in this sample. Your provider will discuss the results with you and may recommend additional testing or treatment adjustments based on the findings.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

What does this test measure?
This test measures qualitative indicators of inflammation in your stool, such as the presence of inflammatory cells or proteins. These markers help identify whether inflammation is present, which can be critical for diagnosing or monitoring conditions like IBD (Crohn’s disease or ulcerative colitis).
How often should I get this test?
The frequency depends on your medical condition and treatment plan. If you have IBD, your provider may recommend regular monitoring to track disease activity. If this test is part of a routine colonoscopy follow-up, ask your provider how often you should repeat it.
Can I eat or drink before the test?
No specific dietary restrictions apply to this test itself, but follow your provider’s instructions for colonoscopy preparation, such as fasting or avoiding certain foods, to ensure the sample is representative and the procedure goes smoothly.
