When labeling at the bedside, which information should be included to ensure traceability?

• A. Patient name, date of birth, unique ID, date/time, and collector initials.
• B. Only patient name.
• C. Room number and bed.
• D. Date only.

Answer: (A)

The important idea here is ensuring traceability of a specimen by tying it clearly to the patient and the person who collected it, with a precise time reference. Including the patient’s full identifiers (name, date of birth, and a unique ID) creates an unambiguous link to the correct medical record, so the sample can be matched to the right patient even if there are others with similar names. Adding the date and time of collection establishes when the specimen was obtained, which is crucial for proper processing, sequencing in the lab, and any time-based testing requirements. The collector’s initials provide accountability and a clear point of contact if questions arise about the collection event, helping maintain the integrity of the chain of custody.

In contrast, relying on only the patient’s name can still lead to mix-ups, since names aren’t unique. Room number and bed can change with transfers, and a date alone doesn’t identify the patient or the exact collection event. Bundling all the identifiers—name, date of birth, unique ID, date/time, and collector initials—gives the strongest, most reliable traceability at the bedside.
