RESUMO

Circulating lymphocytes from 30 patients with sarcoidosis when stimulated in vitro with Kveim-induced macrophage migration factor, the Kmif test, produced a guinea-pig macrophage migration inhibition factor in 21 of 30 cases (70%). In those patients not on steroids the results showed a good correlation with the cutaneous Kveim test. One positive test was found in 16 normal subjects. Our results suggest that the Kmif test may prove a useful rapid alternative to the Kveim test.
