Biobanks should strive to engage actively with contributors and potential contributors to clarify preferences and priorities of return of IFs and IRRs, including the roster of findings to be returned and the methods of return. Biobanks should facilitate the involvement of contributors and potential contributors in biobank policy-setting on this issue. Further research on the preferences, experiences, and outcomes of contributors and research participant populations with return of IFs and IRRs is needed. Researchers in biobank research systems and biobanks themselves have an important role to play in facilitating and conducting that research, to aid progress over time.
