斑贴试验是诊断过敏性职业性皮肤病(过敏性职业性接触性皮炎和职业性湿疹)的重要参考指标之一。但如果斑试物的浓度选择不当,就会影响结果的正确性,导致错误的诊断。目前使用的斑试浓度一般沿用国外的标准或用生产中使用的浓度。为了使斑试浓度标准化,进而制定我国自己的标准,我们进行了本题的研究,现将初步结果总结如下: The patch test is one of the important reference indicators for the diagnosis of atopic occupational dermatitis (atopic occupational contact dermatitis and occupational eczema). However, if the concentration of plaque test material is not properly selected, it will affect the correctness of the result, resulting in a wrong diagnosis. Currently used spot test concentrations generally follow the standards of foreign countries or the concentration used in the production. In order to standardize the spot test concentration, and then develop our own standards, we conducted the study of the problem, the preliminary results are summarized as follows:
