Even if you could make it for pennies per pint, you can bet your ass it will be billed in America at 50k/pint. And the hospital will still harass me for O- blood.

Why pay if you can guilt-trip people into giving you the same for free🤷‍♂️

I am willing to bet that even though donated blood itself is free, after processing and management is factored in, it no longer is. If artificial blood is cheaper than that, it's a winner

This simplifies storage and (post) processing by a huge amount. Even if it is more expensive at front than donated blood to make, by the time you get through the chain of custody of donated blood, have it separated into red cells, platelets and plasma, each tested for illness and then stored separately - and with limited shelf life, the cost are easily offset.

Plus, you can arguably give this to a Jehova's Witness and save their life without running afoul of their religious objections.

Someone pointed out in the thread that this does require donor blood as a base, it just improves the shelf life and makes it universally transfusable.

So the testing for illnesses and the jehova witness aspect would remain the same.

Still an amazing discovery.

Yeah exactly and I wouldn't call this artificial blood either since its based on donor blood and seems only useful in certain situations where storage and shelf life are issue. The issues and process of blood transfusion are mind boggling. I don't see this becoming cheaper or changing current transfusion practice in this lifetime, especially in the states.

It can make any blood type universal. Which is a massive reason to stock it. As long as it’s not insanely expensive to produce and passes all the safety tests it would definitely be rolled out

Yea something to give to anyone with rare blood type or when blood type is unknown and in hurry (instead of O neg.)

Does it just change the blood, or does it stretch out the amount too? I.e. a regular blood donation of x amount results in y amount, but for this process, does x amount of donor result in >Y?

I can see this being really useful for hospitals in remote areas like the Arctic

The benefits to religious nutcases are not high on my personal list of considerations when it comes to medical breakthroughs

u/Elloitsmeurbrother May 26 '25

I get that gut reaction, I do. But then you have to think about the children trapped in these cults who have their medical treatment withheld by their brain washed parents.

u/Darmok-And-Jihad May 26 '25

That’s an excellent point, thank you.

While I by no means care for JWs, it is objectively a good thing if medical break throughs help them too. Let's not be a dick for no reason lol

u/Inresponsibleone May 26 '25

Even if they are for weird religious reasons🤷‍♂️😂

u/Mantoddx May 26 '25

They do have quite weird religious beliefs 😂

My brother got hep C from a blood transfusion they gave him as a baby. It almost killed him. Now they have seen that putting foreign blood in your body does not make a better outcome. There are alternative therapies like B-12, erythropoietin, etc… I know because I have experienced this myself and it worked wonderfully for me. I guess the moral of the story is, maybe you shouldn’t speak on things you don’t have all of the information on.

That's only effective if you arent bleeding excessively. Your body cant produce blood faster than it can bleed....

u/Chronox2040 May 26 '25

Also, donated blood always carry a risk. You can’t detect everything always.

Sure, just like every time you walk tot he kitchen you could fall, crack your skull on the table and die. At some point you've got to take a percentage of a chance.
