Broad consent pertains to storage, maintenance, and secondary research with identifiable private information or identifiable biospecimens.

• Investigators who anticipate that they or others may want to use information or biospecimens collected through the primary research for unspecified secondary research may consider obtaining broad consent from the subjects as part of the informed consent process.
• Never obtain informed consent through a broad consent process. This is an optional procedure. 

See the HHS site 45CFR46.116(c) for additional elements of information that must be provided as part of broad consent.
