What should be done after applying a pre-printed source plasma label?

After applying a pre-printed source plasma label, it is essential to complete all steps in the PDA (Plasma Donation Application) to ensure that the donor is properly linked to their donation number. This step is critical for maintaining accurate records, which is vital in plasma collection and testing processes. The PDA serves as a comprehensive system to track donor information and the specific details of each donation, ensuring that all data aligns with regulatory standards and internal protocols.

Linking the donor to the donation number not only aids in the traceability of the plasma collected but also plays a crucial role in the testing and safety processes that follow. It allows for monitoring of the plasma’s journey through testing and processing, ensuring that each unit is accounted for and that donor information remains confidential and correctly associated with the material they provided.

Other options may seem relevant but do not address the immediate need to ensure proper linkage and documentation in the donation process, making the completion of the PDA the most critical step following the application of the label.
