Even then, you’re only donating 500ml to the recipient; 1/10th their blood volume. Your rate would have to be about 10 times the average for the PFAS in your blood to pose even a moderate risk to them.
And with plasma, most of the volume of your donation is discarded. They extract the proteins and certain other useful components, and toss the rest, including (most of) the PFAS.
My point is that even with (moderately) elevated levels of PFAS, your blood/plasma does not pose a significant danger to recipients. Certainly not one that exceeds the lifesaving value of your blood or plasma.
