eli5: What happens when you get a blood transfusion with the wrong/incompatible blood type?

In: Biology

Answer 1

Depending on how much: you die.

And not only that, but people who have had this happen report feeling a “[sense of impending doom](https://www.medicaldaily.com/tranfusion-reaction-mismatched-blood-type-donations-create-sense-impending-397528)” before they die.

Edit to add that this is why AB+ is the “best” blood type because it can take every single other blood type with not a single issue. It’s the opposite of O- and known as the universal receiver.
