No results posted yet for this study

Summary

This study aims to characterize the diagnostic performance of immunological testing of occult gastrointestinal bleeding in stool in the population aged over 75 years with iron deficiency anemia.

As secondary objectives, the study aims to:

* determine a threshold of positivity optimizing the immunoassay performance for the study population, in accordance with the probabilities of error (false positives, false negatives) and weights (defined by expert consensus) allocated to these errors.
* Assess the benefit of a double measure of bleeding (two stools) by immunoassay compared to a single measure.
