It's possibly slightly unfair that he's not allowed his own 'stash', but he can only donate a certain amount per year and it seems like it's in demand, and apparently it can only be stored for 42 days (according to a very quick Google search).

  I am not aware of whole blood cryostorage for use in transfusions after thawing from -196° C, can you please point me to the literature on this? What I could find via Google searching referred to specimen cryopreservation at this liquid nitrogen-low temperature, and retrieval for future analysis and umbilical cord/placental banking for stem cell retrieval, but not for whole blood banking.

    It's not whole-blood it's RBC: http://www.sanquin.nl/en/products-services/blood-products/sanquin-bank-of-frozen-blood/ http://www.sanquin.nl/en/products-services/blood-products/sa... AFAIK modern transfusions don't generally use whole-blood, and RBC are by far the most important component for rare blood types issue.

  He is allowed his own stash. Source? The article seemed to indicate that he must permit any blood he donates to be used for other people, thereby implying he may not reserve any of it for himself.

    No, I read it as that he donates for himself, but if someone needs blood, and he allows it, they take from his pool reducing what is available for himself.

      No it clearly says that if donates blood he "has to allow anyone" to use it. Which is clearly backed up with the next line stating: He must rely on other Rh_null donors if he needs blood.
