Blood groups are inherited biological characteristics that do not change throughout life in healthy people. Blood groups represent antigens found on the surface of red blood cells. Kell blood group system consists of 31 antigens. Kell antigen (K) is present in 0.2% of the population (the rare blood group). Cellano antigen is present in more than 99% (the high-frequency antigen). These antigens have a distinct ability to cause an immune response in the people after blood transfusion or pregnancy who, otherwise, did not have them before.
