This doesn't fit with what I understand about blood transfusions unless things are different with plasma versus blood.

Blood transfusions – who can receive blood from whom?

People with blood group 0 are called "universal donors" and people with blood group AB are called "universal receivers."

Of course you can always give A blood to persons with blood group A, B blood to a person with blood group B and so on. But in some cases you can receive blood with another type of blood group, or donate blood to a person with another kind of blood group.

The transfusion will work if a person who is going to receive blood has a blood group that doesn't have any antibodies against the donor blood's antigens. But if a person who is going to receive blood has antibodies matching the donor blood's antigens, the red blood cells in the donated blood will clump.

Blood Group	Antigens	Antibodies	Can give blood to	Can receive blood from
AB	A and B	None	AB	AB, A, B, 0
A	A	B	A and AB	A and 0
B	B	A	B and AB	B and 0
0	None	A and B	AB, A, B, 0	0

People with blood group 0 are called "universal donors" and people with blood group AB are called "universal receivers."

If I remember correctly, O negative is the universal donor and AB positive is the universal recepient.

The issue is indeed blood vs. plasma per earlier postings. The info you’ve copied is for blood only. The plasma is the fluid and AB plasma can be given to almost anyone, again per earlier postings and the Red Cross websites I checked. Never knew that or I’d have been doing plasma donations a long time ago.
