Paper tests for occult blood in faeces and some observations on the fate of swallowed red cells

AUTOR(ES)
RESUMO

Paper tests for occult blood were assessed on faecal specimens from adults. An orthotolidine/sodium perborate and a modified orthotolidine/peroxide test were found to be reasonably satisfactory. The Hematest and Occultest tablets and a paper guaiac test were unsatisfactory.
