ANTIBODY OF BLOOD-GROUP SPECIFICITY IN SIMPLE (“COLD”) HAEMOLYTIC ANAEMIAS

Abstract
Two cases of “cold” (simple) haemolytic anaemia are described. The serological investigation showed conclusively that the sera of both patients contained an anti-I antibody and that their cells were I positive. The antibody found is thus a true auto-antibody. This is in keeping with the findings obtained previously in the “warm” (hyperimmune) type of haemolytic anaemia.
