According to federal regulations, how is a human subject defined?

The correct definition of a human subject, according to federal regulations, is a living individual from whom data is collected through interaction or intervention. This definition emphasizes the requirement that the individual is alive and refers to the direct involvement of the subjects in the research process, whether through observation, interviews, or other types of engagement where researchers interact with the subjects to gather data.

This understanding is critical in research involving human subjects, as it highlights the importance of informed consent, ethical considerations, and the need for protecting individuals' rights and well-being in all types of research activities. Such regulations ensure that individuals participating in research have clear details about how their information will be used and have the opportunity to give their consent before any data collection begins.
