- •Subject is able and willing to provide stool samples within the 120 days prior to a colonoscopy procedure
- •Subject is able and willing to undergo a colonoscopy after providing a stool sample
排除标准

结局指标
主要结局
CRC Sensitivity
时间窗: Through study completion, an average of 5 years.
ColoSense sensitivity for subjects with colorectal cancer (CRC), which is the percentage of individuals with a diagnosis of CRC that were detected as positive by the ColoSense test.
AA Sensitivity
时间窗: Through study completion, an average of 5 years.
ColoSense sensitivity for subjects with advanced adenomas (AA), which is the percentage of individuals with a diagnosis of AA that were detected as positive by the ColoSense test.
SPL Sensitivity
时间窗: Through study completion, an average of 5 years.
ColoSense sensitivity for subjects with serrated precancerous lesions (SPL), which is the percentage of individuals with a diagnosis of SPL that were detected as positive by the ColoSense test.
NEG Specificity
时间窗: Through study completion, an average of 5 years.
ColoSense specificity for subjects with negative findings, which is the percentage of individuals with a diagnosis of negative findings that were detected as negative by the ColoSense test.
