Hypersensitivity reactions
Anaphylaxis is a type I reaction (atopic diseases).
Good pasture's syndrome
and Coomb's positive haemolytic anaemia are type II
reaction (antibody to antigenic components).
Serum sickness is a type III
reaction (immune complex disease).
An example of type
IV reaction is contact dermatitis or allograft rejection (T cell
mediated response).
