Testing and Diagnosis

Your doctor will likely diagnose Crohn’s disease or ulcerative colitis only after ruling out other possible causes for your signs and symptoms. He or she will use a combination of tests and procedures, including, but not limited to:

  • Blood tests 
  • Endoscopic procedures, such as colonoscopy and upper endoscopy
  • Imaging procedures, such as x-ray, small bowel imaging, ultrasound or CAT scan

If you have been newly diagnosed with Crohn’s disease or ulcerative colitis, please visit the newly diagnosed page for more information.
