ELIF: why can’t AB+ people accept plasma from other blood types?

Question

I know it has to do with antibodies present in other types. However, if AB+ people can accept whole blood, which contains plasma, from any other blood type, why can’t they accept isolated plasma from any blood type? Wouldn’t the antibodies in the whole blood work the same as those in the plasma by itself?

Answer 1

Plasma from a B+ person may have antibodies against A

Plasma from O- may have antibodies against A, B and +
