People with O blood type are daring, outgoing and go-getters. They have a habit of setting high standard for themselves and do all they can to achieve them. These people have excellent leadership qualities and little things do not bother them, which makes them appear as selfish to other people, especially to A type. Thus AB blood type people can be termed universal patients. But O Rh negative donors can be called universal donors, as red blood cells from such donors can be used for transfusions for all patients.
AB negative is the rarest of the eight main blood types – just 1% of our donors have it. Despite being rare, demand for AB negative blood is low and we don’t struggle to find donors with AB negative blood. However, some blood types are both rare and in demand. Of the eight main blood types, people with type O have the lowest risk for heart disease. People with types AB and B are at the greatest risk, which could be a result of higher rates of inflammation for these blood types. A heart-healthy lifestyle is particularly important for people with types AB and B blood.
