- reverse passive Arthus reaction
- the reaction produced when precipitating antibody is inoculated into a skin site in an experimental animal, followed in 30 minutes to 2 hours by inoculation of the homologous antigen, either intravenously or intracutaneously at the same site. Thus the usual anatomical locations of precipitating antibody and antigen in an Arthus reaction are reversed.
