What is required for ethical research involving human subjects?

• A. Informed consent by patient and IRB oversight
• B. Verbal consent only, no IRB involvement
• C. Consent is optional if study is low risk
• D. Only researchers' approval is necessary

Answer: (A)

Ethical research involving people hinges on two protections: respecting participants’ autonomy through informed consent and ensuring independent review and oversight via an IRB. Informed consent means providing clear information about the study’s purpose, procedures, potential risks and benefits, alternatives, and how privacy will be protected, and obtaining voluntary agreement to participate, usually documented in writing (though in some minimal-risk situations verbal consent with IRB approval can be acceptable). IRB oversight involves an independent board reviewing the protocol to confirm that risks are reasonable in relation to potential benefits, that consent is appropriate and properly obtained, and that safeguards are in place for privacy and for vulnerable populations. Research cannot proceed without both components in most settings, unless a IRB-approved waiver of consent or alteration is granted under regulatory criteria. That combination—consent from participants and IRB review—is what makes research ethical.
