Serum precipitins in pulmonary aspergillosis: preliminary results.

Definitive diagnosis of pulmonary aspergillosis is difficult to establish. Thus, confirmative evidence of active fungal aggression is imperative. In this study, an immunodiffusion test was carried out on 36 cases of pulmonary aspergillosis and two groups of subjects comprising 133 patients with non-fungal diseases and 134 healthy volunteers as controls.
