[Clinical comparison of hemoFEC with Hemoccult II (author's transl)]

Two technically improved methods of testing for occult blood in stool--hemoFEC and Hemoccult II--were compared by parallel tests in 1500 successive unselected out-patients. HemoFEC was positive in 1.9%, Hemoccult in 2.3%, the difference is not statistically significant. But there was a difference in the colour development of the two tests. Six cases of carcinoma, 14 of large polyps and six other sources of bleeding from the colon were revealed in the course of this study.
