Study information
Scientific title
The role of faecal occult blood testing in risk stratification for GI malignancy in subjects with iron deficiency anaemia
Acronym
IDIOM (3)
Study hypothesis
Screening patients with iron deficiency anaemia by means of faecal occult blood testing can identify sub-groups at high risk of underlying gastro-intestinal malignancy, over and above the stratification provided by established clinical criteria.

Condition
Iron deficiency anaemia caused by gastrointestinal malignancy
Intervention
All patients in the study will have a qualitative immunochemical stool test for occult blood prior to gastro-intestinal investigation of the cause of their anaemia.
All patients will be followed up until they have completed investigation of their iron deficiency anaemia, as clinically indicated. The study will assess whether faecal occult blood (FOB) testing at presentation can predict the likelihood of underlying gastrointestinal pathology in subjects with iron deficiency anaemia (IDA) and, in particular, cancer.
