      Pretty much, yes. Sounds rather nefarious, doesn’t it? Taking the dangerous chemicals out of my blood and putting them into someone else?

      The amount of PFAS the recipient will receive from whole blood donation is not enough to appreciably raise their own levels. Even if we replace their complete blood volume with my blood, the absolute highest their concentration of PFAS can get in their body is equal to mine; not higher.

      If they don’t regularly donate blood/plasma as well, it is likely that I have lower levels of PFAS than they start with, and that my less-contaminated blood actually reduces their PFAS concentration.

      For plasma, the news is actually better: (Most of) The PFAS in your donated plasma is discarded along with the rest of the unusable components. Extraction of the various proteins and other components rejects (most of) the PFAS.

      If I remember correctly even though in the United States you can sell your plasma it isn’t used for medical purposes like they claim. Instead it goes into makeup and other crap. Found out apparently it’s illegal to sell your blood and plasma for medical use. You can donate it though.

        With a solid podcast and YouTube video under my belt, you can sell it for medical purposes. The medical industry needs it. They even export it to other country’s medical systems.

          Medical purposes in this case is manufactured blood products.

          Directly transfused blood must be volunteer donations but concentrated clotting agents and such can be made from paid plasma. The assumption was that the process introduces more safeguards but the assumption is, or was, provaby wrong.

          Technically speaking it is legal to use paid plasma for transfusion, it just needs to be marked as such, but it hardly ever happens in legitimate medical institutions.
