Allergic contact dermatitis to Primula obconica has long been established. It is considered a significant allergen in Europe and has been included in standard screening there. The allergen is much less common in the United States. The frequency of allergy to P obconica in the United States is difficult to assess because no series of routine testing to this allergen has been reported. The purpose of this study was to evaluate the frequency of primin allergy in routine testing in a referral patch test center. A series of 567 consecutive patch tests was performed that included primin as part of the standard screening. Only one patient had a positive reaction. Although it is frequently missed and often difficult to diagnose, the frequency of primin allergy in this series was too low to indicate including this allergen as part of routine testing.
对报春花的过敏性接触性皮炎早已被确认。在欧洲，它被认为是一种重要的过敏原，并已被纳入当地的标准筛查项目。该过敏原在美国则不太常见。由于尚未有针对该过敏原的系列常规检测报告，因此很难评估美国对报春花的过敏频率。本研究的目的是评估在一家转诊斑贴试验中心的常规检测中，樱草素过敏的频率。进行了一系列连续567次斑贴试验，其中樱草素作为标准筛查的一部分。只有一名患者出现阳性反应。尽管樱草素过敏常常被漏诊且诊断困难，但在本系列中樱草素过敏的频率过低，不足以表明应将该过敏原纳入常规检测项目。
