[Modified leukocyte migration inhibition test with workers of the buildings and metals industries with chromium eczema].

In 59 workers of metal, building and galvanizing industries a test of leucocytes migration inhibition was carried out. We modified this test so that it consists in that the whole blood was used with no isolated leucocytes, with no plexiglass chambers but with very thin capillaries and short incubation. The result of the test is obtained on the day it is carried out (after 6 hours). A comparison with the results of epidermal test using 0.5% of potassium dichromate confirmed the specificity of the test. The sensitivity of the test was however less, compared to epidermal tests and the standard test of leucocytes migration.
