  • In 10 patients tested ferrous fumarate did not cause intestinal bleeding or interfere with the orthotolidine test for faecal occult blood. The orthotolidine test would seem to be a reliable and sensitive method of testing for faecal occult blood loss and agreed exactly with the spectroscopic pyridine-haemo-chromogen method. Hematest and occultest tablets gave unreliable evidence of the presence or absence of blood in the stool. The results obtained confirm the necessity for careful preparation and examination of the patient prior to carrying out tests for occult intestinal bleeding. © 1963, British Medical Journal Publishing Group.
