Phadiatop和sIgE检测在哮喘病因诊断中的应用

Application of Phadiatop Test and Specific IgE Test in Etiological Diagnosis of Asthma

为探讨CAP过敏原检测系统中Phadiatop检测和特异性IgE（sIgE）检测在小儿哮喘病因诊断中的应用价值，对54例哮喘患儿和47例支气管肺炎患儿及34例喘憋型肺炎患儿进行检测。结果Phadi－atop和尘螨sIgE检测的灵敏度为0．65和0．61，特异度均为0．87，两种检测一致性高。哮喘组阳性率显著高于另两组（P＜0．005）。Phadiatop检测对哮喘病因诊断和治疗具有重要价值，Phadiatop阳性患儿应进一步作SIgE检测。

To evaluate the roles of Phadiatop test and sIgE test for etiological diagnosis, 54 cases of the asthma, 47 cases of bronchopneumonia and 34 cases of the asthmatic pneumonia were investigated. The study showed that Phadiatop test had a sensitivity of 0. 65 and a specificity of 0. 87, and sIgE test to dust mite had a sensitivity of 0. 61 and a specificity of 0. 87 respectively. Fifty-two cases (96%)of asthma demonstrated concordant results between these two tests. Thirty-three cases were assessed as positive, and nineteen were assessed as negative by both tests. The positive rates of the two tests were significantly higher in the asthma group than that in the other groups (P<0.005). The results in-dicated that: Phadiatop test is a useful test for etiological diagnosis and treatment of the asthma;and sIgE test is further needed for the Phadiatop test positive cases.
