Blood bag containing human blood for transfusion. Its blood type (group O,Rhesus positive) is clearly marked on the bag. This refers to the presence of certain proteins on the surface of red blood cells. Blood types must be matched when donated blood is given to a patient (a transfusion),in order to prevent an immune reaction occurring against these proteins | |
