What is so special about O positive blood?
O+ blood has no A or B antigens, and is thus “O” blood. The (+) means that the Rh antigen is present. O+ blood is very important as a (mostly) universal red blood cell type. This blood type can be used in emergency situations such as traumatic bleeding or other types of emergency transfusions.
Which is rare blood type O+ or O?
Types O negative and O positive are in high demand. Only 7% of the population are O negative. However, the need for O negative blood is the highest because it is used most often during emergencies. The need for O+ is high because it is the most frequently occurring blood type (37% of the population).
Is O+ is a universal donor?
Although the blood type O+ can donate blood to all positive blood types (A+, B+, AB+, and O+), it is not a universal donor. Blood type O- is the universal blood donor, meaning that people with this blood type can donate blood to all other types with a lower risk of causing serious reactions.
