Yes, there seems to be an allergic reaction.

是的 看起有敏性反。

I think it's it's a collective anaphylactic immune response to an antigen that challenged the system.

我认为这是对抗原的集体敏性免疫反, 这种抗原挑战了系统。

In other words, sometimes a person might have no allergic reaction on the skin test, but have a localized allergic reaction affecting the nasal cavity and eyes - that's low sensitivity.

换言之，一个在鼻子和眼存在着敏性反的患者在做皮肤点刺试验时可能出现假阴性的结果，这就是所谓的低敏感性。
