The Ulcerative Colitis (UC) Test is a blood test that checks for signs of inflammation and immune activity that may be associated with ulcerative colitis, a type of inflammatory bowel disease. It is not a definitive test for UC but can help a doctor evaluate symptoms like diarrhea, abdominal pain, or blood in the stool.
What it measures
- C-reactive protein (CRP) — A general marker of inflammation in the body.
- Erythrocyte sedimentation rate (ESR) — Another inflammation marker that measures how quickly red blood cells settle.
- Complete blood count (CBC) — Checks for anemia, infection, or other blood changes.
- Antibody markers (e.g., p-ANCA, ASCA) — Proteins that may help distinguish UC from Crohn's disease.
- Albumin — A protein that can be low with chronic inflammation or poor nutrition.
Who it is for
A gastroenterologist or primary care doctor typically orders this test when a patient has ongoing digestive symptoms that might be due to inflammatory bowel disease.
Preparation
No fasting is usually required. Tell your doctor about any medications or supplements you take, as some can affect the results.
