For plasma donation, every individual is tested for blood-borne diseases. They draw an additional whole blood sample first for this test.
This is even more rigorous than what we do for whole blood donation, in which blood samples are pooled and tested as a batch. Ironically, the reason we're able to do this is that we make a larger profit off of plasma donations, whereas we don't for whole blood, and have to use the cheaper testing methods for that.
