About this test
The inflammatory bowel disease (IBD) test uses blood markers to help assess inflammation and support evaluation of conditions such as Crohn's disease and ulcerative colitis. It may include general inflammation markers together with antibody tests that can be associated with IBD. These tests do not diagnose IBD on their own; they provide supporting information when symptoms such as chronic diarrhea, abdominal pain, or weight loss are being investigated. Results are interpreted with imaging, endoscopy, and clinical findings.
What this test measures
- C-Reactive Protein (CRP) A general marker of inflammation in the body.
- Erythrocyte Sedimentation Rate (ESR) A nonspecific marker that can rise with inflammation.
- Complete Blood Count (CBC) Evaluates blood cells and can reveal anemia or other changes with chronic disease.
- Anti-Saccharomyces Cerevisiae Antibodies (ASCA) Antibodies sometimes associated with Crohn's disease.
- Antineutrophil Cytoplasmic Antibodies (ANCA) Antibodies that may be associated with ulcerative colitis and other conditions.
Who this test may be right for
- People with chronic diarrhea or abdominal pain
- Individuals with unexplained weight loss or blood in stool
- Patients being evaluated for Crohn's disease or ulcerative colitis
- People with a family history of inflammatory bowel disease
Before your visit
- No fasting is usually required unless other tests in the order need it
- Report current symptoms and all medications, including steroids
- Tell the phlebotomist about recent infections, which can affect antibody tests
- Follow any additional instructions included with your order
Understanding your results
Elevated inflammation markers such as CRP or ESR suggest inflammation but do not identify its location or cause. IBD-associated antibodies may support further evaluation, but they can also be present without IBD and absent in people who have it. Results are used together with symptoms, imaging, and endoscopy. Discuss your IBD test results and whether more testing is needed with a healthcare provider.

Questions people ask
Can the IBD test diagnose Crohn's disease or ulcerative colitis?
No. This test provides supporting information about inflammation and IBD-associated antibodies. Diagnosis usually requires endoscopy, imaging, and a specialist's evaluation.
What does a positive ASCA or ANCA result mean?
ASCA and ANCA are antibodies that can be associated with IBD subtypes, but they are not definitive. They are interpreted with your symptoms and other tests.
What does an elevated CRP or ESR indicate?
CRP and ESR rise with inflammation anywhere in the body. They support evaluation but do not show where the inflammation is or what is causing it.
Do I need to fast for an IBD panel?
Fasting is usually not required unless the order includes tests that need it. Check your specific instructions.
