New Test for Colon Cancer

Posted: 06.15.2015

A new stool DNA test (Cologuard) has been approved by the FDA.  In a recent study, researchers compared the new stool DNA test with the current FIT (fecal immunochemical test) stool test.  Both tests look for hidden bleeding in the stool, but the DNA test also looks for genetic changes linked to colon cancer.  The new test detected 92% of the earliest and most curable cases compared to FIT, which detected 74%; however, it has a higher false positive rate, 13% versus FIT's 5%.  Abnormal results on the DNA tests would then be confirmed by a colonoscopy.   Cologuard's cost is also higher than FIT.
