In an emergency, anyone can receive type O Red Blood Cells, and type AB individuals
can receive Red Blood Cells of any ABO type. Therefore, people with type O blood are
known as “universal donors” and those with type AB blood are known as
“universal recipients.” In addition, AB Plasma Donors can give to all blood
types.
