<p>A rapid, simple, sensitive and reliable method for detecting fecal carcinoembryonic antigen in stool, indicative of colorectal cancer, is described. The invention is based in part on the discovery that previous methods of removing coarse and gelatinous contaminants from a stool and liquid mixture resulted in removing a significant amount of the CEA. By not removing macromolecules smaller than about 1,000 MW, preferably 5,000 MW, a significant portion of the CEA will remain in the filtered liquid for detection.</p> |
