Kell blood group system

Kell blood group system

A family of red blood cell ANTIGENS designated as the ALLOTYPES KK, Kk, kk and K-k-, believed to be on the short arm of chromosome 2. Antibodies to the K-antigen occur in about 10% of people in England and can cause red cell breakdown (haemolytic) transfusion reactions. The group system is next in importance to the ABO and rhesus systems and is named after a woman whose serum contained the antibodies.

Prenatal typing of Rh and Kell blood group system antigens: the edge of a watershed.
All alloantibodies identified among our study population were clinically significant and are mostly against Rh and Kell blood group systems. Thus we recommend that donors of RBC, as well as recipients' of RBC, should be phenotyped for Rh (D, C, E, c, and e) and [K.sub.1] (partial phenotype matching) before the first transfusion to avoid alloimmunization in SCD patients.
