Question

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

In: Biology

Answer 1

Depends on whats incompatible about it. If its ABO incompatible for example, you could die pretty quickly. If its RhD incompatible, maybe you’ll get a delayed hemolytic transfusion reaction, you’ll not feel great but won’t likely die. If its M/N incompatible, you may not even notice it or know about it until someone pehnotypes you and the units you were given and found it incidentally.

So, like just about everything in the world, it depends.
