应用三抗体免疫放射分析法检测198例呼吸系疾病患者血清中IgE 含量,结果显示,58.1%呼吸系疾病患者均高于正常,以支气管哮喘最明显(P<0.001)。方法的灵敏度分别为:支气管哮喘72.8%,肺炎53.3%,慢支合并肺气肿50.0%,急性支气管炎47.8%,慢性支气管炎47.1%和慢支合并肺心病44.7%。说明血清IgE 水平与呼吸系疾病关系密切,可作为诊断过敏性呼吸系疾病的一项指标。 The level of IgE in serum of 198 patients with respiratory diseases was detected by three-antibody immuno-radiometric assay. The results showed that 58.1% of patients with respiratory diseases were higher than normal and the most obvious was bronchial asthma (P <0.001). The sensitivity of the method were 72.8% for bronchial asthma, 53.3% for pneumonia, 50.0% for chronic bronchitis and emphysema, 47.8% for acute bronchitis, 47.1% for chronic bronchitis and 44.7% for chronic bronchitis and pulmonary heart disease. Description of serum IgE levels and respiratory diseases are closely related, can be used as an indicator of allergic respiratory disease diagnosis.
