Which statement about labeling is correct?

• A. Two Identifiers And Date/Time Are Optional.
• B. Labels Can Be Omitted If The Patient Is Known.
• C. Labeling Is Only Needed For Blood Samples.
• D. Correct Labeling With Two Identifiers And A Date/Time Is Essential To Prevent Misidentification And Ensure Traceability.

Answer: (D)

Accurate labeling hinges on clearly identifying the patient and recording when the specimen was collected. Two identifiers—such as the patient’s name and date of birth (or a patient ID)—confirm the sample belongs to the right person. Adding the date and time creates a time-stamped record that supports proper processing, tracking through the lab workflow, and accurate association of results with the correct collection event. Without these elements, a specimen could be misidentified, leading to wrong results, inappropriate treatment, and difficulties tracing the sample’s history.

Labeling isn’t optional, even if the patient is known, because the physical link between the specimen and the order must be maintained for every sample. And labeling isn’t limited to blood samples; all collected specimens require proper labeling to ensure correct identification and traceability.

That’s why the statement emphasizing two identifiers with a date/time as essential best captures the safety and traceability goals of labeling.
