Q. Is FIT effective for repeated testing in a large group setting?
A. According to research conducted by Kaiser Permanente Northern California (KPNC) and Southern California (KPSC), over 4 rounds of annual screening was conducted to assess the performance characteristics of FIT. The researchindicated that the test's positivity, predictive values, and sensitivity declined slightly after the first round but then remained relatively steady. This indicates that annual strategic FIT screening is feasible and effective for colorectal screening in a large community based setting.
