Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
GRAIL, the company that developed the Galleri test and is sponsoring this study, would like to learn more from individuals who have received the Galleri multi-cancer early detection test. The purpose of this study is to understand how health information can be accurately collected from the medical records of individuals who have received the Galleri test in a real world setting. The collected information may include relevant medical and cancer history, diagnostic test results, including the Galleri test result. This will help GRAIL build a future larger study for individuals who have taken the Galleri test. This future study is important for understanding patient journeys after a Galleri test (including any diagnostic testing done and any diagnoses made), for improving the Galleri test, and to contribute to other research on cancer screening.
