O+ here, the blood centre wants my plasma more often than my blood, but around peak road accident times they want my blood
If they’re not paying you for plasma as an O+ don’t do it, unless you specifically have some unusual subtyping thing.
Apheresis plasma as anything but A or AB is just not something blood banks really need that much for transfusions, and industrial use can damn well pay for you for the privelege.
They aren’t allowed to pay donors in Australia. There are worries that payment would attract people who shouldn’t donate and incentivise them to lie on the qualification form
Neat.
Then don’t waste your life and risk your health to give them O plasma they don’t need for transfusions for free.
