What is required from both identifiers before proceeding with a transfusion?

For a blood transfusion, it is essential to have a reliable identification process to ensure patient safety and to avoid any potentially life-threatening complications. The correct choice highlights the necessity of confirming both identifiers through a signature and name with designation on the requisition form. This step ensures that the medical laboratory staff and transfusion team can verify the identity of the patient receiving the blood product against the blood type and product specified.

The signature confirms the identity of the individuals responsible for the order and indicates that appropriate checks have been carried out to match the patient with the correct blood component. Additionally, including the designation helps to clarify the professional status of the individual, making the process more secure and traceable.

Other methods of identification, such as oral confirmation or solely initials, might not provide the same level of accountability and verification that the full signature and name do. Blood transfusions are critically serious procedures that are subject to strict protocols designed to prevent errors; therefore, adhering to comprehensive identification verification steps is crucial.
