I've read a few HN comments before regarding this that blood donation actually helps you get rid of some of these chemicals since the body is forced to regenerate new blood or something like that (i'm not saying its a good idea to donate for the sake of getting rid of chemicals and i'm not even sure if this is medically correct in the first place). But does the donated blood get cleaned or something of these things before it goes to the new patient? I'd hate for it to get transferred to the other poor guy who already suffers from some condition.

The donated blood does not get cleaned. There is a screening step that looks to throw out blood with (some) infections. There is also a separation step to split red blood cells, platelets, and plasma (recipients have variable needs) before storage and eventually use. EDIT: it’s worth mentioning that the screening step does include some filtration. White blood cells do get pulled out of the blood, but I’m not sure how common it is for a lab to do that.

  Never mind just filtering the blood supply, if there's some kind of filtering/dialysis that removes chemicals and micro plastics sign me up! Let everybody go in once a year and get their blood cleaned. Maybe send the bill to DuPont

    Then you'd have to worry about what they put back in.

    I would assume that piping your blood through any kind of machine will have vastly greater risks than leaving whatever you might be able to filter out in your body.

If you work at a Teflon factory or otherwise have high exposure, maybe you stay away from donating blood. But everybody has some PFAS in their blood at this point. The need for blood is worth the small risk

There’s always the all-natural, centuries-old alternative of leeching!
