Primary outcomePrimary: Ct Value (Ct Values From PCR Reaction) — 38.4; 44.3; 44.6 Ct
Summary
The purpose of this study is to evaluate the performance of the SEPT9 gene methylation assay in Colorectal cancer (CRC) high-risk population in Chinese hospitals using the opportunistic screening method. The trial plans to evaluate a Chinese domestic SEPT9 assay kit produced by BioChain (Beijing) Science and Technology Corporation, who is a close partner of Epigenomics AG, the producer for Epi proColon 2.0 CE.
