Why This Test Matters
Calprotectin is released when white blood cells respond to inflammation in the intestines. High levels may signal chronic inflammation, which can be linked to conditions like Crohn’s disease or ulcerative colitis. This test helps doctors monitor disease activity and guide treatment decisions without relying on invasive procedures like endoscopy.
What to Expect Before the Test
No special preparation is needed. You’ll provide a small stool sample collected using a provided collection kit. The sample is then tested in the lab to measure calprotectin levels. Results are typically available within a few days.
How the Test Works
A stool sample is analyzed using a specialized probe that detects calprotectin, a protein associated with inflammation. The test quantifies the protein’s concentration to determine if inflammation is present or active in your digestive system.
Possible Results and Next Steps
Elevated calprotectin levels may suggest inflammation, while normal levels generally indicate no significant inflammation. Your doctor will interpret results in the context of your medical history and symptoms to determine the next steps, which could include further testing or treatment adjustments.
