Immunodiffusion reactions of several different commercial fungal extracts from organisms were compared to those obtained from patients' environments. Sera were obtained from patients suspected of having hypersensitivity lung disease (HLD). There was a difference in reactivity among the sources of the antigen and in some lots of antigen from the same commercial supplier. The results demonstrate a wide variation in the reactivity of different antigenic extracts and emphasize the need for uniform standardization of preparations used in precipitin tests.
将几种不同的市售真菌提取物与从患者环境中获得的提取物的免疫扩散反应进行了比较。血清取自疑似患有过敏性肺病（HLD）的患者。抗原来源之间以及来自同一商业供应商的某些批次抗原之间的反应性存在差异。结果表明不同抗原提取物的反应性差异很大，并强调了沉淀素试验中所用制剂统一标准化的必要性。
