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).

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.
