Retesting 50 patients with stasis dermatitis after a period of time (3-25 months) revealed significantly less positive patch test results (p less than 0.05). All procedures were, of course, standardized. The main reasons for this were elimination of the sensitization agents in the interim and testing with a less acute skin condition. Allergens that are difficult to avoid, such as the 'para' compounds and balsam of Peru and related substances, show a higher degree of persistence in subsequent patch testing.
一段时间（3 - 25个月）后对50例淤积性皮炎患者进行重新检测，结果显示斑贴试验阳性结果显著减少（p小于0.05）。当然，所有操作都是标准化的。主要原因是在此期间致敏原已被清除，且检测时皮肤状况没那么严重。难以避免的变应原，如“对二”化合物、秘鲁香脂及相关物质，在后续斑贴试验中显示出更高的持续性。
