How DNA Stool Testing Works

The DNA Stool Test is a state-of-the-art test designed to detect colon cancer early – when it's most treatable.

DNA Stool Testing does not diagnose colon cancer, it is a screening test. All cancer cells have DNA mutations. When a cancer grows in the colon, it sheds cells into the stool. This test examines a stool sample for 23 DNA markers that are associated with colorectal cancer and pre-cancerous polyps.

  • Positive Results: A DNA marker has been found. Your next step is to see your doctor for immediate follow-up.
