Summary

This study is testing a new blood test to quickly identify people who may have colorectal cancer. It aims to help doctors decide who needs urgent care, especially when colonoscopy appointments are delayed. The study will include 400 adults who either had a positive stool test or were already diagnosed with colorectal cancer.
