Descriptive Information
Brief Title REFLECTION: A Clinical Practice Learning Program for Galleri
Official Title REFLECTION: Real World Evidence for Learnings in Early Cancer Detection, a Clinical Practice Learning Program for Galleri™
Brief Summary REFLECTION is a prospective cohort study that will enroll approximately 35,000 patients who have opted to be screened with Galleri, a blood-based, multi-cancer early detection (MCED) test as part of their routine medical care. The purpose of the study is to understand the performance of the test in clinical settings and the impact on patients and healthcare providers.
