Anti‐LW Specificity in Autoimmune Acquired Hemolytic Anemia

Abstract

Anti‐LW has been demonstrated in six unselected cases of acquired hemolytic anemia, either by direct testing or after absorption of the sera and cell eluates with Rh‐positive or Rh‐negative LW‐negative cells. Another antibody which is directed toward the Rh complex is also present as indicated by reactions with all bloods except Rh null . A third agglutinin, apparently nonspecific, is indicated by the reactions of some sera with all bloods including Rhnull null .
