Diagnosing Crohn’s and Colitis

Crohn's and Colitis

Continuing our endoscopy series and today, we look at what tests you may be required to undergo, if your doctor suspects you may have Crohn’s and Colitis. 

You may need to undergo some tests and investigations to make sure you have a correct diagnosis. And the following are common tests for Crohn’s and Colitis.

Blood and stool tests

Blood tests can show whether you have inflammation somewhere in your body and whether you are anaemic. They can also show whether you are getting the correct vitamins and minerals, and check whether organs such as your liver and kidneys are functioning correctly.

Your stools can also be tested for signs of bleeding or inflammation, and to check whether your diarrhoea is caused by an infection. If inflammation is confirmed, you may then have an examination to look inside your body, such as an endoscopy, X-ray, or scan.


Endoscopy (carried out using an instrument called an endoscope) is the general term for a type of test that enables your Consultant to look directly at the inside of your digestive system. These tests can be carried out at Benenden Hospital in the purpose-built endoscopy suite.

The different types of endoscopy that can be carried out by the Benenden Hospital team when investigating symptoms that may suggest Crohn’s and Colitis are:

  • Gastroscopy: used when your food pipe (oesophagus), stomach, or top part of the small intestine need to be looked at.
  • Colonoscopy: comes into play when your bowel needs to be looked at.
  • Flexible Sigmoidoscopy: used when the Consultant needs to look inside the lower part of your bowel.

X-rays and scans

X-rays, including barium swallow, ultrasound, and MRI scans can also be used in the diagnosis process. Why not look at our recent Health News articles about the Imaging Suite at Benenden Hospital?
