Overview

Classification


Category	Features

Warm-antibody type	Due to IgG subtype Extravascular hemolysis
Cold-antibody type	Due to IgM subtype Intravascular hemolysis Recognition by the reticuloendothelial system Destruction by macrophages
Mixed warm-antibody and cold-antibody type	Due to IgM subtype Mixed features

Intravascular haemolysis
Red blood cell lysis occurs in the circulation as a result of activation of the complement system cascade.

Extravascular haemolysis
Red Blood Cells that are coated with antibodies are specifically recognised in the reticuloendothelial system and destroyed by macrophages.
