What this test is
This test typically measures certain proteins or blood markers that can rise when the digestive tract is inflamed. It does not confirm Crohn's disease by itself; instead, it gives your clinician one piece of information to consider with your history, exam, and other tests.
What it measures
- C-reactive protein (CRP) — a general marker of inflammation in the body
- Erythrocyte sedimentation rate (ESR) — an indirect sign of inflammation that can rise with many conditions
- Fecal calprotectin — a stool marker that reflects inflammation in the intestines
- Fecal lactoferrin — another stool marker that can indicate intestinal inflammation
- Anti-Saccharomyces cerevisiae antibodies (ASCA) — an antibody sometimes checked when distinguishing types of inflammatory bowel disease
What the test involves
The test usually requires a standard blood draw from a vein in your arm. In some cases, a stool sample may be collected instead or in addition, depending on what your clinician orders.
Why it is often ordered
A clinician may order this test when someone has ongoing digestive symptoms such as diarrhea, abdominal pain, or weight loss that could be related to inflammation. It can also be used to help monitor known inflammatory bowel disease over time.
Preparation
Preparation is usually minimal, but specific instructions can vary by the collection site and the exact test ordered. Follow the lab's instructions, and ask the collection lab if you are unsure about fasting or medications.
How results are reported
Results are reported as numeric values for each marker, often with a reference range provided by the performing laboratory. Reference ranges vary by laboratory, so your clinician will interpret your results in the context of your overall health.

- Whether fasting is required for your specific test order
- Which sample type will be collected, such as blood or stool
