采用酶免疫分析法对367例过敏性疾病患儿进行特异性IgE测定。发现367例过敏性疾病患者中过敏性紫癜组的食入性过敏原阳性率显著高于吸入性过敏原,而哮喘、过敏性鼻炎吸入性过敏原阳性率则显著高于食入性过敏原,皮炎、荨麻疹的食入性和吸入性无显著差异。认为血清过敏原测定为过敏性疾病的预防、诊断和治疗提供依据。 Enzyme immunoassay was used to detect specific IgE in 367 children with allergic diseases. Found that 367 cases of allergic diseases in patients with allergic purpura ingestion of allergens positive rate was significantly higher than inhaled allergens, and asthma, allergic rhinitis inhalation allergen positive rate was significantly higher than food-borne allergens, Dermatitis, urticaria ingestion and inhalation no significant difference. Serum allergen determination that the prevention, diagnosis and treatment of allergic diseases provide the basis.
