Now do the reverse. Who can save whose life. :D

AB+ are all "blood is blood", but nobody wants their shit-tier dodgy blood!

[–] tophneal@sh.itjust.works 46 points 6 months ago (2 children)

They may not want our whole blood, but they loooove our plasma

AB plasma doesn't contain A or B antibodies, so it can be safely transfused to all blood types.

It ends up being more complicated. You get enough infusions as AB+ and you'll start picking up strange antibodies that increase your chance for that sense of impending doom

Similarly you could likely receive O+ blood if you were O- without adverse effects, but only once.

[–] ggtdbz@lemmy.dbzer0.com 7 points 6 months ago

Yeah we don’t really mix blood types at all here in Lebanon, and I really doubt they do anywhere else. Universal donor and universal recipient is just theory, in practice it’s easier to receive O- than AB+ because AB is really uncommon (as is the case everywhere).

AFAIK the A/B and Rhesus antigens are not the only markers and there are more blood compatibility components that are taken into account if possible.

I have a relative who has an unfortunate condition that causes internal bleeding. They've had enough blood transfusions that their antibodies are completely haywire.

Multiple times, doctors have not listened to their protests, and given them O-. They turn an impressive shade of yellow (among other, more serious, issues).

Last I heard, there were 2 compatible donors known, 1 in a different country. Thankfully, you can store blood longer term. It's just not cost efficient to do in bulk. They have their own little stockpile of blood at their local hospital (mostly self donated).

All I see is the smiles 0-:

[–] Scubus@sh.itjust.works 20 points 6 months ago (1 children)

And then theres rh null who cant recieve from anyone basically

[–] psud@aussie.zone 9 points 6 months ago (1 children)

I presume they would do as many O- people do and have blood drawn for their own use if they expect they might need it

[–] Scubus@sh.itjust.works 9 points 6 months ago (1 children)

Yeah, thats what my doctor recommended for me. I just really hate needles

[–] AnUnusualRelic@lemmy.world 8 points 6 months ago (1 children)

It can also be done with blades.

[–] Scubus@sh.itjust.works 7 points 6 months ago (1 children)

Yeah extracting it isnt difficult but putting it back in... i dont think can be done with blades

[–] Reddfugee42@lemmy.world 9 points 6 months ago

Not with that attitude

[–] cordlesslamp@lemmy.today 14 points 6 months ago (1 children)

Years ago I read somewhere that they discovered a way to remove something from the blood and make it universal, like eliminate blood type all together.

Wonder how that research going?

[–] cRazi_man@lemm.ee 16 points 6 months ago (1 children)

It's expensive and blood can only be stored for so long. Easiest to stick with compatible blood types.

There are also loads of other antigens in blood that can cause a reaction. These are just the commonly known ones. So blood should still be cross matched anyway if it isn't an emergency.

[–] DragonTypeWyvern@midwest.social 8 points 6 months ago

And, quite frankly, we actually are getting somewhat close to producible artificial blood, so there's just not a whole lot of need for the investment.

And those artificial blood studies have DARPA money behind them.

Only [YOUR BLOOD TYPE HERE] homies can interact with this comment.

[–] rustyfish@lemmy.world 9 points 6 months ago

Just found out Khorne is AB+.

[–] Dbumba@hexbear.net 8 points 6 months ago (1 children)

AB+ Gang rise up. Universal recipients (sigma parasite) and universal plasma donors. When receiving blood sometimes I'll mix A, B, and O just to flex.

[–] psud@aussie.zone 2 points 6 months ago (1 children)

O+ here, the blood centre wants my plasma more often than my blood, but around peak road accident times they want my blood

[–] DragonTypeWyvern@midwest.social 0 points 6 months ago (1 children)

If they're not paying you for plasma as an O+ don't do it, unless you specifically have some unusual subtyping thing.

Apheresis plasma as anything but A or AB is just not something blood banks really need that much for transfusions, and industrial use can damn well pay for you for the privelege.

[–] psud@aussie.zone 4 points 6 months ago (1 children)

They aren't allowed to pay donors in Australia. There are worries that payment would attract people who shouldn't donate and incentivise them to lie on the qualification form

[–] DragonTypeWyvern@midwest.social 0 points 6 months ago (1 children)

Neat.

Then don't waste your life and risk your health to give them O plasma they don't need for transfusions for free.

I am very familiar with the industry. I am telling you that you are being taken advantage of to benefit a for-profit company that your presumably non-profit blood banks sell your donations to.

It's one thing when that's to defray their quite high cost of operating, and they're selling plasma that would otherwise be wasted.

It's another thing when they have you coming in just to con you out of plasma.

Blood for the ~~Blood God~~ Red Cross

[–] milicent_bystandr@lemm.ee 3 points 6 months ago

Now ask plasma...
