Stool DNA test results may include:

  • Negative result. A test is considered negative if DNA markers common to colon cancer or precancerous polyps and signs of blood are not found in the stool.
  • Positive result. A test is considered positive if DNA markers common to colon cancer or precancerous polyps or signs of blood are found in the stool sample. Additional evaluation, such as a colonoscopy to examine the colon, may be recommended to determine the cause.
