Ultra-sensitivity Quantitative Fecal Immunochemical Test in Detecting Colorectal Advanced Adenoma and Colorectal Cancer

Early detecting and removing of colorectal advanced adenomas can reduce the incidence of colorectal cancer. Because of the less bleeding of advanced adenomas, sensitivities of the common used quantitative fecal immunochemical tests (qFITs) are unsatisfying. Ultra-sensitivity qFIT(us-qFIT) can determine extremely low fecal hemoglobin concentration compared with the common used qFIT. This study will prove the diagnostic accuracy of us-qFIT in detecting colorectal advanced adenomas.
