The Inflammatory Bowel Disease (IBD) Test is a blood test that looks for signs of inflammation in the body. It is often ordered when a person has ongoing digestive symptoms like diarrhea, belly pain, or weight loss, to help tell IBD apart from other conditions.
What it measures
- C-reactive protein (CRP) — A protein made by the liver that rises when there is inflammation somewhere in the body.
- Erythrocyte sedimentation rate (ESR) — A test that measures how quickly red blood cells settle; a faster rate can suggest inflammation.
- Complete blood count (CBC) — Checks for low red blood cells (anemia) or high white blood cells, which can happen with inflammation.
- Fecal calprotectin (if stool sample is also given) — A stool test that shows inflammation specifically in the intestines, but it is not part of the blood test.
Who it is for
This test is usually ordered by a primary care doctor or a gastroenterologist (a doctor who treats digestive diseases) when a patient has symptoms that could be IBD.

Frequently asked questions
Does a high result mean I have IBD?
Not necessarily. Many things can raise these markers, including infections or other inflammatory conditions. Your doctor will consider the full picture.
Can this test rule out IBD?
No. Some people with IBD have normal blood test results, so doctors may still recommend other tests like a colonoscopy.
How long do results take?
Results are typically ready in 1 to 3 business days.
Is this test covered by insurance?
Coverage depends on your insurance plan and why the test is ordered. Check with your insurance provider or the lab.
