Human Subject

A human subject is a living individual who becomes a participant in research. The subject may be a patient or a healthy individual and may be the recipient of the intervention or a control.

Individuals whose information is gathered about other than the research participants are considered to be secondary subjects. This can include information about family members that is recorded in a way that the other individual may be readily identified. Parent of pediatric participants, children of adult participants, and family members of any participants are common secondary subjects. Identifiable data from elicited from secondary subjects must be justified by the investigator.
