Stool DNA Test

A stool DNA test is a non-invasive screening tool that analyzes stool samples for genetic material from abnormal or cancerous cells shed by colorectal tumors. By detecting specific DNA changes associated with colorectal cancer or polyps, the test helps identify potential issues early, when they are most treatable. It is typically used as an alternative to colonoscopy for average-risk individuals and can be done at home, making screening more accessible. A positive result usually leads to further diagnostic procedures, like a colonoscopy, for confirmation and treatment planning.
