What is the proper labeling information for a specimen?

• A. Specimen type and color.
• B. Patient name, unique ID, date/time of collection, specimen type, collector initials.
• C. Lab-specific internal code only.
• D. Date of birth only.

Answer: (B)

Accurate specimen labeling hinges on identifiers that uniquely tie the sample to the patient and the collection event, so results go to the right person and reflect the correct timing and test requirements. The best labeling includes the patient name, a unique patient or internal ID, the date and time of collection, the specimen type, and the collector’s initials. Each piece matters: the patient name and unique ID ensure the sample is linked to the correct patient; the date and time document when the specimen was obtained, which can affect stability and the testing window; the specimen type clarifies what is being tested and how it should be processed; and the collector’s initials provide accountability and a way to verify who collected the specimen if questions arise.

Other options fall short because they don’t provide all the necessary, uniquely identifying information. A label with only the specimen’s color or appearance does not identify the patient or link to the requisition. Relying on a lab-specific internal code alone omits patient identity, making it impossible to attribute results to the correct person. A date of birth alone lacks the collection context and can be non-unique, increasing the risk of misidentification.
