Understanding Your Fecal Calprotectin
Fecal calprotectin is a stool test that measures inflammation in the intestines. It helps tell whether digestive symptoms come from inflammation or from a non-inflammatory cause.
What It Measures
Calprotectin is a protein released by white blood cells when the intestines are inflamed. Higher levels in the stool mean more inflammation in the gut.
It is especially helpful for telling apart inflammatory bowel disease (IBD), such as Crohn’s or ulcerative colitis, from irritable bowel syndrome (IBS), which does not cause this kind of inflammation.
What Your Results Can Mean
| Result | What It Means |
|---|---|
| Normal / LowLittle Inflammation | Inflammatory bowel disease is unlikely. Symptoms are more likely from a non-inflammatory cause like IBS. |
| ElevatedInflammation Present | Suggests inflammation in the intestines. This may warrant further evaluation, sometimes including a colonoscopy. |
What’s Most Important to Know
Calprotectin can also rise temporarily from infections or certain medications like NSAIDs, so we interpret it in context.
This test helps decide who needs more invasive testing and who does not. Dr. Mui will explain your result and any next steps.
