Why is it important to not complete step 3 in the PDA?

The importance of not completing step 3 in the PDA revolves around the necessity to identify any label errors prior to moving forward in the process. If a label error is present, it could lead to serious implications for safety and accuracy in the donation process, such as mislabeling a blood product or creating complications in patient care. Ensuring that all labelling is correct is critical because a simple mistake can have far-reaching consequences. Completing step 3 without addressing potential label errors would compromise the integrity of the entire procedure and could pose risks to both donors and patients receiving the plasma. Thus, it is crucial to first resolve any label discrepancies before proceeding to further steps in the process.
