Crohn’s Disease
Diverticular Disease

This test is commonly ordered as a routine screening to aid in the early detection of Colon Cancer. Yearly testing is recommended for people age 50 and above. This test may also be ordered by people experiencing symptoms of anemia.

Because certain conditions may cause intermittent bleeding, results from multiple specimens may be required for results to be conclusive. If blood is detected, it is important that a doctor is consulted to determine a diagnosis. Additional procedures such as a colonoscopy may be required.
