There are 4 main blood groups types of blood A, B, AB and O. Your blood group is determined by the genes you inherit from your parents. Each group can be either RhD positive or RhD negative, which means in total there are 8 blood groups.
Blood group O is the most common blood group. Almost half of the UK population 48%has blood group O. Receiving blood from the wrong ABO group can be life-threatening. For example, if someone with group B blood is given group A blood, their anti-A antibodies will attack the group A cells.
This is why group A blood must never be given to someone who has group B blood and vice versa. As group O red blood cells do not have any A or B antigens, it can safely be given to any other group.
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.
Type O people have been linked to characteristics such as confidence, determination, resilience, and intuition, but they are also supposedly self-centered and unstable. Chances are higher you’ll live longer if you have type O blood. Experts think your lowered risk of disease in your heart and blood vessels ardiovascular disease may be one reason for this.
People with O negative blood were once called “universal” red cell donors because it was thought they could donate blood to anyone with any blood type. But now experts know there can even be risks with this type of blood.
