Crohn's disease can be difficult to diagnose as its symptoms can mimic those of other digestive disorders. However, there are several tests and procedures that can help detect Crohn's disease.
The first step in diagnosing Crohn's disease is a physical exam and review of a patient’s medical history. During the physical exam, a doctor may check the patient’s abdomen for signs of tenderness or swelling. A doctor may also ask the patient about any family history of IBD, as well as about any other digestive issues the patient may have.
In addition to a physical exam, doctors may also order blood tests to check for anemia, elevated white blood cell counts, and other signs that may indicate inflammation.
The next step in diagnosing Crohn’s disease is imaging tests. This may include an upper gastrointestinal (GI) series, which uses X-rays to look for any abnormalities in the small intestine. A doctor may also order a CT scan or MRI to look for any blockages or other signs of intestinal inflammation.
The final step in diagnosing Crohn's disease is a colonoscopy or endoscopy. During these procedures, a doctor will insert a flexible tube with a camera into the patient’s digestive tract. The doctor can then view the area and take tissue samples for further testing.
Overall, Crohn’s disease can be difficult to diagnose due to its variable symptoms, but physical exams, blood tests, imaging tests, and endoscopic procedures can help detect the condition.
