Blood test may boost colorectal cancer screening in underserved communities
NCT ID NCT06929481
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether offering a blood test (cell free DNA) alongside standard stool tests and colonoscopy increases colorectal cancer screening rates among people who are not up-to-date with screening. The trial enrolls 340 adults aged 45-75 at a health center serving low-income and minority groups. Participants are randomly assigned to receive either standard screening options or expanded options that include the blood test, and researchers will compare how many complete screening within 60 days.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Cell free DNA (cfDNA) blood test
What this could lead to
If successful, this could show that offering a simple blood test increases colorectal cancer screening rates among groups who currently face barriers, helping reduce health disparities.
What could go wrong
This is a small, early-stage pragmatic trial focused on screening completion, not cancer detection or survival. The blood test is less sensitive for advanced polyps than colonoscopy, so it may miss some precancerous growths.
