How is Ulcerative Colitis Diagnosed?
The diagnosis of ulcerative colitis can be obtained from the symptoms. Certain blood and stool tests are done to rule out an infection that can simulate the disease. A visual exam of the lining of the rectum and lower colon (sigmoidoscopy) or the entire colon (colonoscopy) is always needed. This exam usually reveals a characteristic pattern. Small painless biopsies are taken which show certain features of ulcerative colitis. A barium enema X-ray of the colon is also needed during the course of the disease.
