Summary

This study is exploring whether molecular clues in stool and saliva samples can predict the presence of colorectal polyps. About 1,000 adults scheduled for a colonoscopy will provide samples beforehand, which will be analyzed and compared with their colonoscopy results. The goal is to develop and validate a noninvasive test that could one day help screen for polyps without the need for a colonoscopy.

What this could mean

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

What this could lead to
If successful, this could lead to a simple, noninvasive test that helps identify people who may have colorectal polyps, potentially reducing the need for colonoscopies in low-risk individuals.
What could go wrong
This is an observational study, not a treatment trial. The test may not be accurate enough to replace colonoscopy, and results are still being validated.
