does this imply that you're just giving shitty blood to people that need life saving procedures?
Also, I'm not certain how much they treat blood, but I wouldn't be surprised if it ends up being a purification system sort of similar to Dialysis where you rely on an external machine for removing impurities.
Fwiw, it is the responsibility of the blood banks to do due diligence testing.
2 questions: is there any other kind? If there were, ate people requiring transfusion in a position to make demands to the donors (not vendors)
If the blood don't contains long term detrimental pathogen, that's seems like an okayish tradeoff.
Feels a little homeopathy... How many people can we put the same blood through?
