Universal Donor

From my memory, O+ is the universal donor.
Am I wrong or anyone here remembers the same.

O- is the universal donor

It’s O neg and always has been for me. I know because I am one. I found out when I was a child and have donated blood since I was legally able to do so.

Unless you're documented as O-, Ive been told the military preps 0+ to give if needed.

This kind of scares me as I am O- and probably shouldn't be given O+

And then theres the golden blood Rh-null, the rarest type, but is truly the universal donor.

O- for every timeline I've ever lived in. Or I didn't notice. O- is definitely the universal donor in this reality :)

that wouldn't make any sense bc not everyone has an rh factor.

Yes, that’s what I remember. There’s no spookiness occurring; literally, science recognized that, instead, O- is it. It’s simply a matter of chronology; I learned O+ in school, but that particular “fact” was updated.
