Development of a Blood Test with Prospective Study Cohort of 100,000 Participants

The STRIVE Study is a prospective, observational, longitudinal, cohort study that has enrolled approximately 100,000 women at the time of their screening mammogram. A subset of the data from STRIVE will be used to help validate GRAIL’s blood test for the early detection of multiple cancer types. Participants completed a health questionnaire and provided a blood sample around the time of their screening mammogram and will be followed for up to five years to capture clinical outcome data, including cancer diagnoses.

Current Status: Follow-up

Thank You for Your Contribution
