Crohn’s Disease Diagnosis

It generally takes a lot of time to find the Crohn’s disease, it would even take years. Doctors will start the diagnosis by gathering information about your health history, diet, other symptoms, environment and family history details. After then they will do physical examinations through and add to your record of symptoms.


Lab Test:

Lab tests are required in order to look for any problems linked to intestinal inflammation and thereby early identification of the disease. Lab tests may include:

  • Blood protein levels
  • Body mineral levels
  • Red blood cell counts
  • White blood cell counts
  • Blood sedimentation rates
  • Stool samples to check for blood or infectious microbes

These tests check if there are signs of infection, inflammation, internal bleeding, and low levels of substances such as iron, protein, or minerals.

Endoscopy and Biopsy

The doctor may recommend an endoscopy to investigate the interior of your colon with a small camera mounted to the end of a lighted tube. There are two types of endoscopic examinations: a colonoscopy and an upper endoscopy.

  • Colonoscopy involves: A flexible tube called colonoscope is inserted through the opening of the anus and allows the surgeon to examine of the colon, the lowest part of the large intestine.
  • Upper Endoscopy: It is also known as Gastroscopy. It involves the insertion of a flexible tube through the mouth, down the esophagus to examine the inner walls, into the stomach and into the first part of the small intestine.

After the visual analysis, the doctor will take samples of the affected parts of the colon. The collected samples would be admitted for further tests.


Chromoendoscopy is a procedure of applying stains or dyes on the surfaces of the tissues to enhance the characterization of the tissues, this helps in identifying even the slightest changes in the tissue lining. The surgeon generally sprays a blue liquid dye during the colonoscopy and the technique may identify early or flat polyps which can be biopsied or removed.  

After Chromoendoscopy the patient is advised to follow a temporary diet and patients would witness a blue discharge as the dyes are washed.

Small Intestinal Imaging

Another test with latest medical techniques is the small intestine imaging, which is used to visualize some of the portions of your intestine which could not be fully examined by colonoscopy and endoscopy. These tests include drinking an oral "contrast" and having a fluoroscopic x-beam, CT scan or filter, or Magnetic Resonance Imaging filter. These tests are regularly alluded to as enterography, or if certain sort of difference is utilized
