Summary

This study investigates whether a blood test can help identify people who have a positive stool test for hidden blood but are actually at very low risk for colorectal cancer. The goal is to reduce the number of unnecessary colonoscopies, which are invasive and strain healthcare resources. Researchers will compare blood biomarker results with colonoscopy findings in 1,000 screening participants.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: blood biomarker test
What this could lead to: If successful, this could make colorectal cancer screening more personalized and reduce the number of unnecessary, invasive colonoscopies.
What could go wrong: The blood test may not be accurate enough to replace colonoscopy, and the study is still in early stages, so results are not yet proven.
