title: K22, a 'new' para-Kell antigen of high frequency.
abstract: An alloantibody is described which detects a high frequency blood group antigen absent from Ko cells but different from all the reported Kell and para-Kell antigens. The family study shows the antigen to be inherited but gives no information about its relationship to the Kell locus. It is suggested that this 'new' para-Kell antigen be called K22.
