Should be done in combination with gFOBT or FIT test.

DOUBLE-CONTRAST BARIUM ENEMA (DCBE)
The DCBE is an x-ray of the colon and rectum that highlights abnormal areas. The entire colon must be cleaned out. The contrast solution is inserted through the anus and then drained.

The entire colon must be cleaned out. Air is pumped into the colon and the CT scan is taken. If abnormalities are found, the appropriate diagnostic procedure is performed.

FECAL OCCULT BLOOD TEST (GFOBT)
The gFOBT test is an in-home test used to detect blood that cannot be seen by the naked eye occurring in or on bowel movements. Stool is placed on a test strip, and sent to a facility that tests it for blood. Test results of either “positive” or “negative” determine if bleeding is occurring; however, it will not indicate the cause. To provide accurate samples, patients need to follow drug and dietary restrictions. The test is typically returned via mail pouch to the doctor or lab. If a test result is positive, a diagnostic colonoscopy should be performed.
FECAL IMMUNOCHEMICAL TEST (FIT)
The FIT test works like the gFOBT test, however unlike the gFOBT, there are not drug and dietary restrictions. The FIT is better at detecting blood than the gFOBT.
STOOL DNA TESTS
These tests look for abnormal sections of DNA in the stool rather than blood in the stool. A kit is provided, and the stool is mailed to a lab that looks for DNA.
