Occult Blood, Stool, Guaiac Test

This test is designed to detect occult blood in the stool. Although several gastrointestinal conditions can lead to bleeding, occult gastrointestinal blood loss is highly suspicious for colon cancer. Consequently, the most common use for this test is as a screen for colon cancer.

Colon cancer is the second leading cause of cancer-related deaths in the U.S. It is important to diagnose and treat colon or rectal cancer as soon as possible. If not treated, the cancer can spread through the bowel wall to lymph nodes and the bloodstream and to other parts of the body.
