針對平均風險的成人，糞便潛血反應檢查（gFOBT 或 FIT）建議每年執行一次，以利早期偵測潛伏的消化道病變。此頻率較高是因為該篩檢敏感度隨時間降低，相較於大腸鏡的檢查間隔長度，糞便篩檢必須維持高頻率才能有效捕捉息肉轉變為癌的跡象。
For average-risk adults, fecal occult blood testing (gFOBT or FIT) is recommended once a year for early detection of occult gastrointestinal lesions. The high frequency is required because the test's sensitivity decreases over time; compared with the longer screening interval of colonoscopy, fecal screening must be performed frequently to effectively capture the transition from polyp to cancer.
