How Is Crohn's Disease Diagnosed?

A variety of diagnostic procedures and lab tests are used to distinguish Crohn's disease from other inflammatory gastrointestinal conditions like ulcerative colitis.

First, your doctor will review your medical history. A specialist called a gastroenterologist may perform a colonoscopy or sigmoidoscopy to obtain bowel tissue for analysis. Other tests your health care provider may order include:

  • Blood tests, including blood counts (often high white blood cell counts -- a sign of inflammation -- and low red blood cells counts -- a sign of anemia from blood loss -- are present).
  • Stool samples to rule out infections as the cause of diarrhea.
  • Special X-rays (such as a CT scan or MRI) of both the upper and lower gastrointestinal tract may be ordered as well to confirm the location of the inflammation.
