title: Leukocyte migration agarose test (LMAT) in sarcoidosis using Kveim test material.
abstract: The two-stage leukocyte migration agarose test (indirect LMAT), shown to be a sensitive in vitro assay for cell-mediated immunity, was used to study Kveim reactivity in vitro in patients with sarcoidosis. No Kveim-induced inhibition of leukocyte migration in agarose or Kveim-induced lymphocyte transformation in vitro was found in 23 patients with sarcoidosis, suggesting that the Kveim reaction is not an expression of cell-mediated immunity.
