The identification of Crohn's disease is often conducted by using a combination of testing methods. Our Adult Gastroenterology Associates team may begin the diagnostic process by discussing your health history, the signs and symptoms you have noticed, and any family history of IBD or Crohn's. After performing a physical exam, they may order endoscopic tests (such as a colonoscopy and an EGD) and lab work involving blood and fecal samples. MRIs, CT scans, and other imaging procedures might also be carried out to diagnose Crohn's disease.
