Detailed explanation-1: -Universal donors are those with an O negative blood type. Why? O negative blood can be used in transfusions for any blood type.
Detailed explanation-2: -For emergency transfusions, blood group type O negative blood is the variety of blood that has the lowest risk of causing serious reactions for most people who receive it. Because of this, it’s sometimes called the universal blood donor type.
Detailed explanation-3: -Those with O positive blood can only receive transfusions from O positive or O negative blood types. Type O positive blood is one of the first to run out during a shortage due to its high demand.
