- What to review next
MLS · Sample question
An ED lavender-top tube for a CBC arrives in the hematology area with no patient label. The electronic order and requisition show two identifiers, and the nurse calls to say the specimen is from the correct patient and is needed urgently. As the MLS receiving the specimen, what is the most appropriate next laboratory action?
B is correct: an unlabeled tube has failed patient-identification requirements and creates wrong-patient risk; the MLS should follow policy, document, and obtain recollection or an authorized exception process. C is unsafe because relabeling from a requisition does not prove specimen identity. D would release a result that fails specimen acceptability standards. A is tempting in an urgent case, but a physician’s verbal approval does not replace laboratory identification policy or required escalation.
