​Processing Emergency Department Orthopedic Test Requests - Process Flow


This document provides a diagrammatic depiction of how to process specimens collected on orthopedic patients with a fracture from the Emergency Department.[i]


  • When fracture patients presenting to the Emergency Department are likely to require transfusion, it is desirable to ensure that pre-transfusion testing has been done in anticipation of the decision to transfuse, to facilitate timely provision of product by the Transfusion Medicine Laboratory. However, this sometimes leads to requests for pre-transfusion testing in circumstances that are rarely associated with the need for transfusion. Avoiding unnecessary testing is good stewardship of laboratory resources that are better used in other ways.

  • This algorithm has been developed to assist decision-making when pre-transfusion testing is requested for fracture patients in the Emergency Department.
