Tests and procedures
Crohn’s disease and ulcerative colitis can be challenging to diagnose as the symptoms are similar to other gastrointestinal conditions. Here is an overview of how your doctor may tackle investigations:
- Complete an accurate medical history
- Physical examination
- Laboratory tests such as X-rays to exclude other sources of your symptoms
- Barium meal X-ray to help see inside your bowel clearly
- Blood tests to look for anaemia and inflammatory markers
- Stool sample to rule out infection or confirm inflammatory cause
- Intestinal imaging using computed tomography (CT) scanning or colonoscopy, sigmoidoscopy, gastroscopy to look for visible signs of inflammation, ulcers or bleeding
- Biopsy of sections of your digestive tract to confirm the presence of inflammation and to check for infection
There are many tests and tools you may come across when you are being investigated for IBD. For a general overview of the types of imaging tests you may be subjected to, you can visit The Gut Foundation’s gastrointestinal diagnosis page.
