Fecal Occult Blood Testing
Fecal blood tests, whether by FIT or guaiac, are also less sensitive for detection of right-sided colorectal neoplasms with sensitivities only about half that seen for left-sided neoplasms. This reflects the degradation of the analytes (both globin and heme) that occurs with bacterial digestion during colon transit.
