What this test is
This test usually refers to a group of blood and stool tests that look for signs of inflammation or immune activity associated with ulcerative colitis. It does not diagnose ulcerative colitis by itself, but it can help a clinician decide whether further evaluation is needed.
What it measures
- C-reactive protein (CRP) — a general marker of inflammation in the body
- Erythrocyte sedimentation rate (ESR) — another nonspecific indicator of inflammation
- Fecal calprotectin — a stool marker that reflects inflammation in the intestines
- Fecal lactoferrin — a stool marker that can suggest active intestinal inflammation
- Antibody panels such as p-ANCA — immune proteins that may be associated with certain types of colitis
- Complete blood count (CBC) — checks for anemia or other blood changes that can accompany chronic inflammation
What the test involves
Most versions of this test require a standard blood draw from a vein in your arm. Some related tests may also ask for a stool sample, which you collect at home or at the lab according to instructions.
Why it is often ordered
A clinician may order this test when someone has ongoing diarrhea, abdominal pain, or blood in the stool that could suggest inflammatory bowel disease. It is also used to monitor known inflammation or to help distinguish ulcerative colitis from other digestive conditions.
Preparation
Preparation depends on which specific tests are included, so follow the instructions provided by the collection lab. In general, no special preparation may be needed for a blood draw, but a stool test may have its own timing or diet instructions.
How results are reported
Results are reported as numeric values or as positive, negative, or indeterminate findings, depending on the specific marker. Reference ranges vary by laboratory, so your results should always be interpreted using the range provided by the lab that performed the test.
