Expanded ColorectAlert™ Studies

Two additional studies, concluded in 2002, showed ColorectAlert™ to be more sensitive for early-stage cancer than the existing standard test (FOBT).

In the first study, 750 patients provided two samples each that were processed in separate labs at different times to demonstrate that ColorectAlert™ results are reproducible and consistent. All patients also underwent colonoscopy, allowing for further correlation between ColorectAlert™ values and colonoscopy results. All patients in the study were scheduled for colonoscopy, but for various reasons, including symptoms, family history of disease and screening.

The second study examined 500 patients scheduled for colonoscopy, and took two samples from each patient. The first sample was taken prior to bowel cleansing and the second was taken after cleansing to determine the effect of cleansing on ColorectAlert™ results.
