Mal d 1 is not equally distributed over the apple. We aimed to examine the influence of the location of pricking in the apple on prick-to-prick skin prick test (PTP) results. PTPs were performed in autumn 2007 and spring 2008, before the birch pollen season, in 32 Dutch adults with symptoms of oral allergy to fresh apple, using apples harvested in autumn 2007. PTPs with fresh intact and unpeeled Pink Lady, Golden Delicious, Elise, Santana and Modi apples were performed using material obtained from approximately 2 cm near the stalk (top), and the middle region. All PTP responses were greater when performed with apple material near the stalk than from the middle region. In 2007, these differences were statistically significant for Pink Lady, Golden Delicious and Elise, and in 2008, for Pink Lady and Modi. When performing PTPs, the apple should be pricked near the stalk rather than in the middle.
苹果上的花粉过敏症（Mal d 1）并非均匀分布。我们旨在研究在苹果上的不同刺点位置对针刺皮试（PTP）结果的影响。2007 年秋季和 2008 年春季，在桦树花粉季节之前，我们对 32 名有新鲜苹果口腔过敏症状的荷兰成年人进行了 PTP 测试，使用的是 2007 年秋季收获的苹果。使用来自叶柄附近（顶部）和中间区域的大约 2 厘米的新鲜完整和未削皮的粉红女士、金冠和 Elise、Santana 和 Modi 苹果进行 PTP。当使用靠近叶柄的苹果材料进行 PTP 时，所有 PTP 反应都大于从中部区域进行 PTP 时的反应。2007 年，粉红女士、金冠和 Elise 的 PTP 差异具有统计学意义，2008 年，粉红女士和 Modi 的 PTP 差异具有统计学意义。进行 PTP 时，苹果应在叶柄附近而不是在中间进行针刺。
