Which statement best describes the requirement for documenting chain of custody during specimen labeling in a clinic?

• A. Chain of custody is never required.
• B. Chain of custody is always documented for every specimen.
• C. Document labeling and chain of custody if required.
• D. Chain of custody is only needed for specimens sent to a provincial lab.

Answer: (C)

Chain of custody shows who has handled the specimen from the moment it’s collected through labeling, storage, transport, and submission, ensuring the sample’s integrity and traceability. In a clinic, you document this only when policy, accreditation, or the receiving lab requires it. Many specimens handled entirely in-house don’t need formal chain-of-custody records, while others—such as samples sent to external laboratories or those involved in regulatory or legal contexts—do require documented custody. So the statement that best fits is: document labeling and chain of custody if required. This approach aligns actions with actual requirements, ensuring accountability when custody needs to be demonstrated, and avoiding unnecessary paperwork when it isn’t.
