Final answer:
Investigator B’s research is not considered human subjects research because the biospecimens are de-identified and the identifiers are not shared, ensuring participant privacy in accordance with federal regulations and IRB guidelines.
Step-by-step explanation:
According to the definition of human subjects research in the federal regulations, Investigator B’s research using the biospecimens would not be classified as human subjects research. This determination is because Investigator B cannot readily ascertain the identity of the source individuals and has agreed not to attempt re-identification of the source individuals. Since the specimens are coded and the identifiers are not shared, the biospecimens are effectively de-identified, which aligns with the ethical and legal standards for protecting research participants' privacy.
Institutional Review Boards (IRBs) play a crucial role in ensuring the ethical conduct of research involving human subjects. These oversight committees review research proposals with these ethical considerations in mind, including the handling of biological specimens and associated data. Compliance with IRB regulations and federal regulations is vital to ensuring that ethical considerations, especially concerning participant privacy, are upheld in research activities.
