If type O blood is transfused into a person with blood type B what will need to be done to the blood?

Since a patient with Type B blood has B antigens on their RBC's and since Type O blood has both anti-A and anti-B antibodies present in the blood plasma, the donor blood needs to be treated before transfusion. The Type O blood needs to be separated into packed cells and plasma, usually done by centrifuge, and only the packed cells should be used for the transfusion. Remember the anti-B antibodies are present in the Type O blood plasma and could cause serious damage in the system of a patient with Type B blood.

If you receive a blood transfusion, you are under no obligation to "return" (or "donate") any blood to back the blood bank. This is true both before and after receiving a blood transfusion - i.e you do not have to have donated blood previously, before you can have a transfusion. (At least, this is how it works in the UK). Nice to know, really.
