Why is O the universal donor but O+ is not?
O positive blood can’t be used universally because it has the Rh factor, but it is compatible with all positive blood types including O+, A+, B+, and AB+. Since over 80% of the population has a positive blood type, type O positive blood is in high demand.
Why O positive is universal donor?
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.
How is type O universal donor?
O negative blood can be used in transfusions for any blood type. Type O is routinely in short supply and in high demand by hospitals – both because it is the most common blood type and because type O negative blood is the universal blood type needed for emergency transfusions and for immune deficient infants.
