migration inhibition test

an in vitro test for detection of cell-mediated immunity (or delayed hypersensitivity) in which peritoneal exudate cells (lymphocytes and macrophages) are packed in capillary tubes and placed in a medium; if the medium contains an antigen to which the lymphocytes are primed, macrophage migration from the tubes is inhibited by lymphokines, particularly macrophage inhibiting factor, released by the antigen stimulated lymphocytes.
