The project uses fecal hemoglobin and transferrin dual-index combined with reagents that can be self-tested at home (referred to as fecal protein dual-index detection reagents), combined with colorectal cancer risk factor questionnaires, to carry out colorectal cancer screening in people of specific ages in the city, aiming to achieve early screening, early diagnosis and early treatment, and evaluate the effect of fecal protein dual-index detection reagents in early screening of colorectal cancer, so as to provide a scientific basis for optimizing the national screening program.
