New blood test aims to cut unnecessary colonoscopies after cancer screen
NCT ID NCT07479381
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This pilot study tested a blood-based test (Harbinger test) to help decide who needs a colonoscopy after a positive colorectal cancer screening. The goal was to see if the blood test could accurately predict colorectal cancer or advanced adenomas. However, the study was terminated early and only enrolled 14 people, so the results are not conclusive.
