两种抗肺炎支原体抗体检测方法比较

目的：探讨早期诊断肺炎支原体（MP）感染的实验室检测方法。方法：分别采用胶体金法和被动凝集法检测77例呼吸道感染住院患儿血清中的抗肺炎支原体抗体，并对两种方法的诊断特异度和灵敏度进行比较。结果：胶体金法和被动凝集法的诊断灵敏度分别为92.3％和97.4％，诊断特异度分别为97.4％和94.7％；二者检测结果的差异无统计学意义（P＆gt;0.05）。结论：胶体金法和被动凝集法均为支原体肺炎早期诊断较理想的方法，但前者的试验方法更为快速且成本更为低廉。

Comparison of two anti-mycoplasma pneumonia antibody detection methods

Objective：To explore the sensitive and specific methods to be used in the early diagnosis of Mycoplasma pneumonia. Methods：Separately used the Colloidal Gold and the SERODIA-MYCOⅡpassive agglutination method in the examination of MP antibody in the blood sera of 77 children hospitalized for respiratory infections, and compared the diagnostic specificity and sensitivity of the tow methods.Results：The sensitivity of the Colloidal Gold and the SERODIA-MYCOⅡpassive agglutination are 92.3%and 97.4%respectively and the specificity are 97.4%and 94.7%respectively;the difference between them are not statistically significant （P＆gt;0.05）. Conclusions：Both the Colloidal Gold and the SERODIA-MYCOⅡpassive agglutination method can be used in the early diagnosis of Mycoplasma pneumonia, but the Colloidal Gold method is more rapid and cheap.
