Your title is a little off.
Blood and plasma are slightly different, plasma is the liquid component of blood and AB is the universal donor when it comes to plasma.
With blood O- is the universal donor and AB is the universal recipient.
My whole famnily are O-, Red Cross calls us all the time.

The above is entirely correct. I am used to donating whole (AB) blood, which can help only about 4% of the population, but of course it frees up an O, A, or B unit for someone else. With plasma, it’s the other way around.
I think I am type O but I am not sure what you are saying about it.
