Human subject means a living individual about whom an investigator (whether professional or student) conducting research obtains
- Data through intervention or interaction with the individual, or
- Identifiable private information.
Intervention includes both physical procedures, by which data are gathered (for example, venipuncture), and manipulations of the subject or the subject's environment that are performed for research purposes. Interaction includes communication or interpersonal contact between researchers and subjects.
Private information includes information about behavior that occurs in a context, in which an individual can reasonably expect that no observation or recording is taking place, and information, which has been provided for specific purposes by an individual and which the individual can reasonably expect will not be made public (for example, client or medical records or information obtained in an interview).
