The test is an accurate way of looking at the lining of the colon. The procedure involves swallowing a capsule that is roughly the size of a vitamin pill. The capsule will then pass through your digestive tract.
As it travels through your colon, the capsule will take thousands of images. Throughout the process you will also be required to drink 1-3 “boosters” to stimulate the movement of your bowel and to help with the excretion of the capsule.
The length of the procedure varies greatly from individual to individual.
