Cancer screening is a proven way to detect cancer early, when it’s most treatable. However, 1 in 3 eligible Americans do not complete colorectal cancer screening in part because they find the current options unpleasant or inconvenient.1

Blood-based screening tests like Shield that can be completed as part of a simple blood draw have the potential to improve screening adherence and identify more cancers early, when they are most treatable.

Our ECLIPSE study validates Shield as a high-sensitivity blood test for colorectal cancer screening.
