After gathering a medical history, a doctor (usually a gastroenterologist) will perform a number of exams and tests to diagnose Crohn’s Disease. They will likely start with a physical exam to check for bloating and abdominal tenderness and listen to the sounds of the GI tract. Other diagnostic tests may include blood tests to detect anemia and inflammation, stool tests to rule out other diseases, endoscopies (such as a colonoscopy) to view the GI tract lining and collect biopsies, or imaging tests such as a computed tomography (CT) scan.[1]
