What are the results of a calprotectin stool test like?
If the Calprotectin in your stool is high, it is a sign that you might have IBD or other underlying conditions such as infection or colorectal cancer.
If it is moderate or low, this implies you have little to no inflammation in your intestines. Your condition may then be diagnosed as IBS or a viral infection.
The reference range in which calprotectin levels are measured is based on numerical values indicated as μg/g (microgram/gram). The reference range for the Calprotectin stool test according to the University of Iowa Department of Pathology Laboratory Services Handbook is:
- Normal or low-level results (49μg/g or less): If your results come out as a low level of Calprotectin, your doctor may only recommend self-care measures, such as relaxation, dietary changes, and certain exercise to help relieve symptoms. They may also prescribe antidiarrheal and antispasmodic medication [9] you.
- Moderate/borderline elevated level results (50-120μg/g): If your results come out as moderate level, your doctor will suggest that you retest. Some medications to help relieve symptoms will also be prescribed for you. In the case of an infection, antibiotics may also be prescribed.
- High-level results (120μg/g and above): if your results come out as high level, additional diagnostic tests, like a colonoscopy will be recommended. This will help make a proper diagnosis and determine the next step.
