Which details are typically documented for each transfer of a specimen on a chain-of-custody form?

• A. Dates and times, signatures, and transfer locations
• B. Donor's medical history
• C. Lab budget numbers
• D. Instrument serial number

Answer: (A)

Keeping the chain of custody intact hinges on traceability of every specimen handoff. For each transfer, you record when the transfer happened, who handled it (their signature), and where the specimen moved to or from (transfer locations). Together these details prove the exact sequence of custody and verify that no tampering or unauthorized access occurred during movement.

Dates and times establish the timeline and show there were no gaps or unexplained delays. Signatures authenticate the responsible individuals, confirming who took custody at each step. The transfer locations document the physical path the specimen followed, ensuring there’s a clear record of each custody point.

Donor’s medical history isn’t part of this process; it’s sensitive clinical information, not required for tracking the specimen’s custody. Budget numbers are administrative and not relevant to the integrity trail, and instrument serial numbers belong in equipment logs or QC records rather than the specimen’s transfer record. Some forms may include extra fields like packaging conditions or temperature, but the essential elements remain the date/time, signatures, and transfer location.
