A new approach to fecal occult blood testing based on the detection of haptoglobin

Abstract

The assay developed in this study has several advantages compared with current fecal occult blood tests, including no requirement for dietary restriction and the ability to distinguish between upper and lower gastrointestinal bleeding, while retaining the sensitivity and specificity of the current tests. Furthermore, the sensitivity of the tests increases to 100% if the FE14.1 and HemeSelect are combined. In addition, the study shows the potential to produce anticancer agents by immunizing with fecal material.
