[Quantitative skin test and inhalation provocation test in asthma using platinum salts]

In this article, the in vivo test results obtained from workers of two platinum separating plants are described. A total of 30 out of 102 workers in two platinum separating plants and 0/40 control subjects showed a positive skin reaction on being provoked with platinum compounds. Twelve out of 15 workers and none of 5 control subjects showed a positive reaction to the bronchial provocation test; this indicates that both tests are highly specific. Three workers with negative skin test reactions showed a clearly positive immediate reaction to the bronchial provocation test with platinum compounds.
