NPS Phlebotomy Practice Exam

Accurate specimen labeling hinges on linking the sample to the correct patient and order. The best label includes the patient's full name, a unique identifier, the date and time of collection, the collector's initials, and the tests ordered. The patient's full name helps identify the person, but a unique identifier (like an MRN or accession number) guarantees the specimen is tied to the exact patient, avoiding mix-ups with others who share a name. The date and time of collection provide the precise collection event, which is crucial for interpreting specimen integrity and timing. The collector's initials add accountability, showing who obtained the sample in case questions arise. Listing the tests ordered on the label ensures the lab processes the correct analyses and correctly links results to the intended orders.

The other options include information that isn’t needed on a standard specimen label or belongs elsewhere. Address and physician name are not essential for identifying and processing the specimen and can raise privacy concerns, while tests charged and certain codes are administrative details better placed on requisition or billing records rather than the label.
