Read our Colorectal Cancer research guide →Researchers are testing whether a blood test measuring special molecules called ofCS (oncofetal chondroitin sulfate) can improve colorectal cancer screening and diagnosis. Currently, many people get colonoscopies that find nothing wrong, which is uncomfortable and wastes healthcare resources. This study will see if the new blood test, combined with existing screening tests, can more accurately predict who really needs a colonoscopy.
In Denmark, over 30,000 colonoscopies are performed each year on patients who turn out to have no cancer or precancerous growths. This new blood test could reduce unnecessary procedures while still catching cancers early, when treatment works best.

If you qualify, you will be asked to donate a single blood sample before your scheduled colonoscopy. Depending on which screening pathway you're in, you may also be asked to provide a stool sample for a standard screening test. That's it — the study simply collects your samples alongside your regular colonoscopy procedure, with no extra visits or long-term follow-up required.
