Irritable bowel syndrome can be a very difficult diagnosis to make. IBS is called a diagnosis of exclusion, which means a doctor considers many other alternatives first, performing tests to rule out other medical problems. Some of these tests may include laboratory studies, imaging studies (such as a CT scan or small intestinal X-rays), or a lower GI endoscopy (colonoscopy). An endoscopy is a procedure in which a flexible tube with a tiny camera on one end is passed into the GI tract while the patient is under conscious sedation.

• A combination of history, physical examination, and selected tests are used to help diagnose irritable bowel syndrome.
  
  
• No single blood test or x-ray study confirms a diagnosis of IBS.
