STOOL EXAMINATION, OCCULT BLOOD

Frank blood can easily be seen in the stool but occult blood present in the stools cannot be seen with the naked eye. This can be due to several conditions in the digestive tract such as polyps, cancer, ulcers, fissures, diverticular disease etc. Certain foods have to be avoided 3 days prior to the test like meat, raw fruits & vegetables as they can affect the test result.
