Are there any specifications on who must be identified as the qualified transfusionist (EP 2) and the second individual (EP 3)?

Any examples are for illustrative purposes only
The “qualified individual/ transfusionist” is determined by the organization considering any professional guidelines, state laws and regulations that define qualifications necessary to transfuse blood and blood products. The organization must also ensure the qualified individual/ transfusionist is competent in transfusing blood and blood products and the identification verification process defined by the organization.  

The second individual involved in a two-person verification process is determined by the organization. This individual must be competent in conducting the identification verification process for blood and blood products defined and implemented by the organization.
