Detailed explanation-1: -Group O can donate red blood cells to anybody. It’s the universal donor.
Detailed explanation-2: -What Is A Universal Blood Type? In an emergency situation where a patient’s blood type is unknown, type O negative blood is the only blood type that is safe to use. The reason is that it is compatible with all blood types. Type O negative is known as the universal blood type.
Detailed explanation-3: -Why is O + a universal donor? Although O+ is considered to be a universal donor, O-is the actual universal donor because A, B, and Rh antigens are absent in the latter. So, it can be given to anyone, irrespective of the blood group.
Detailed explanation-4: -Those with O positive blood can only receive transfusions from O positive or O negative blood types.
Detailed explanation-5: -Who can receive O negative blood? O negative donors are often called ‘universal donors’ because anyone can receive the red blood cells from their donations. Although about 8% of the population has O negative blood, it accounts for around 13% of hospital requests for red blood cells.
