The wristband does not match the order

A patient arrives at 09:10 for a basic metabolic panel and a prothrombin time. The printed order shows a full name and medical record number (MRN). The wristband carries the same MRN but a different first name, the result of a recent legal name change that has not yet reached every system. The patient, awake and able to speak, states the new name and date of birth when asked. Supplies are still unopened.

This is the moment that decides the rest of the encounter. A technically perfect venipuncture performed on an unreconciled identity can still produce a misidentified specimen, and a misidentified specimen can drive a wrong result to the wrong chart. The Clinical Laboratory Improvement Amendments (CLIA) require written procedures for positive patient-specimen identification and for specimen integrity from collection through reporting, and the Clinical and Laboratory Standards Institute (CLSI) PRE01 standard treats identification as a process that runs through the whole preexamination, examination, and postexamination path, not a single glance at a wristband.

The collector must obtain the intended specimen from the intended patient without creating preventable harm or misidentification. Everything that follows, from identifiers to tube order to labeling, serves that one question.

Before any supply is opened, the order, the wristband, and the patient's own words have to agree, or the collection waits.
