Bowel symptoms like bloating, stomach pain and diarrhoea are common and can really interfere with your life - our calprotectin test can help identify what's causing these symptoms.

It's often difficult to tell the difference between irritable bowel sundrome (IBS) and inflammatory bowel disease (IBD) based on symptoms alone, so guidelines recommend taking a calprotectin stool test to rule out inflammation.

Low calprotectin levels mean there's no gut inflammation and your symptoms are more likely to be caused by another condition such as IBS. If you have high calprotectin levels, then there may be inflammation in the bowel causing symptoms.

Your calprotectin test result will come with your actual calprotectin level, recommendations on how to interpret your level from one of our doctors and a formal lab report you can download to share with your doctor if necessary.

What do the calprotectin test results mean?

We interpret faeccal calprotectin levels as follows:

Calprotectin level (µg)Meaning
<50Normal - no gut inflammation
50-250Borderline - possible mild gut inflammation. Recommend to repeat the calprotectin test in 2 weeks
>250High - likely gut inflammation

What's tested in your Calprotectin Test?

  • Faecal Calprotectin

    The calprotectin test checks the level of calprotectin in your stool. Raised levels of calprotectin in the stool are a biomarker for gut inflammation.
