Summary

This study looks at whether offering a blood test (Guardant Shield) can increase colon cancer screening in people who are overdue. About 500 adults aged 45-85 will either get a standard reminder to screen or also have the option to give a blood sample. The goal is to see if the blood test option leads to more people completing screening within 6 months.

What this could lead to
If successful, this could show that a simple blood test helps more people get screened for colon cancer, potentially catching it earlier.
