What action should be taken for a donor with a previous reaction?

The most appropriate action for a donor with a previous reaction is to notify the donor and assess their history. This is essential because understanding the nature and severity of any past reactions can help determine whether it is safe for the donor to give plasma again. By engaging with the donor, collection staff can review their medical history, any prior adverse events related to donations, and any changes in their health status. This careful assessment ensures the safety of both the donor and the recipients of the plasma, and it helps prevent potential complications during the donation process. This proactive approach is critical in maintaining donor safety and in upholding the integrity of the donation system.
