title: Auto-immune hemolytic anemia caused by anti-K13.
abstract: A case of auto-immune hemolytic anemia caused by auto anti-K13 is described. Direct antiglobulin tests using monospecific reagents showed that IgG and the C3 component of complement were present on the patient's red cells. Eluted auto-antibody did not react with Ko or with K:--13 cells. Kell blood group antigenicity of the patient's red cells did not appear to be reduced.
