Auto‐Immune Hemolytic Anemia Caused by Anti‐K131

Abstract
A case of auto-immune hemolytic anemia caused by auto anti-K13 was described. Direct antiglobulin tests using monospecific reagents showed that Ig[immunoglobulin]G and the C[complement]3 component of C were present on the patient''s red cells. Eluted auto-antibody did not react with K0 or with K:-13 cells. Kell blood group antigenicity of the patient''s red cells did not appear to be reduced.
