鼻咽部系列呼吸道病毒检出率比较

Comparison of Detecting Rates From Serial Specimens of Respiratory Virus From Nasopharynx

为了提高临床快速检测呼吸道病毒的检出率，采用系列单克隆抗体联接碱性磷酸酶抗碱性磷酸酶（ＡＰＡＡＰ）桥联技术，取１００例呼吸道感染病人鼻部和咽部分泌物做配对检测。结果显示：咽部分泌物检出率达８２％，鼻部分泌物检出率为３２％。二者阳性检出率经χ２检验，具有显著性差异（χ２＝５０．９９９，Ｐ＜０．００５）。提示：采集呼吸道感染病人咽部分泌物标本送检，可提高病毒检出率。

To enhance the detecting rate of quickly detecting the respiratory virus,the pairing determination of secretions from both nasal cavity and pharynx of 100 patients with respiratory tract infection with serial monoclonal antibody linked alkaline phosphatase-antialkaline phosphatase(APAAP) bridging technique.Results showed that detecting rates were 82% in pharynx and 32% in nasal cavity.There was significant difference(χ 2=50.999,P<0.005),suggesting that detection of pharynx secretion may enhance the detecting rate.
