title: Rapid in vivo destruction of Yt(a+) erythrocytes in a recipient with anti-Yta.
abstract: A patient with anti-Cartwright (anti-Yta) is reported. Immunohematologic studies showed this antibody to be an IgG immunoglobulin that does not bind complement. A 51Cr red blood cell survival study resulted in a greatly reduced half-life of less than six hours of Yt(a+) cells. The antibody titer increased threefold after the red blood cell survival study. Determination of red cell survival is indicated when crossmatch-incompatible blood transfusion is considered.
