AI-Powered blood test aims to spot colorectal cancer
NCT ID NCT06889844
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing a new blood test that uses artificial intelligence to find markers for colorectal cancer. Researchers want to see how often the test gives a false positive result in 250 people who have other cancers or gut diseases. Participants give one blood sample, and their medical records are checked for risk factors. The goal is to make colorectal cancer diagnosis easier and more accurate.

- blood test
- What this could lead to
- If successful, this could lead to a simple, accurate blood test to help diagnose colorectal cancer earlier.
- What could go wrong
- This is an early observational study, not a treatment trial. The test may still have false positives or not work as well in larger, more diverse groups.
