目的:分析胶体金免疫层析法对呼吸道合胞病毒(RSV)抗原快速检测的灵敏度和特异度。方法用 RSV 抗原检测试剂盒(胶体金免疫层析法)对197例疑似 RSV 感染患者的鼻咽抽吸物或鼻咽拭子标本进行检测,以反转录聚合酶链反应(RT-PCR)核酸检测结果为参考,比较胶体金免疫层析法对不同类型标本和不同年龄组患者的灵敏度。结果197例患者标本中经 RT-PCR 检测,95例(48.2%)为阳性。以 RT-PCR 核酸检测结果为标准,胶体金免疫层析法的灵敏度和特异度分别是34.7%和100%。该方法对鼻咽抽吸物的阳性检出率较鼻咽拭子高(36.2%对8.6%,P <0.01),鼻咽抽吸物标本的灵敏度明显高于鼻咽拭子(22.1%对12.6%)。RSV 检出率与年龄呈负相关(P <0.01),1岁以下患儿的阳性检出率最高(29.5%),而在>5岁患儿中阳性检出率为0。结论胶体金免疫层析法对1岁以下幼儿的鼻咽抽吸物中的 RSV 有较好检测效果,可辅助临床进行早期筛查。但鉴于该方法灵敏度较低,且适用于5岁以下儿童,临床上还需用 RT-PCR 对 RSV 进行确认和补充检测,以免漏诊。

Objective To investigate the sensitivity and specificity of colloidal gold immunochromatography assay in rapid detection of respiratory syncytial virus (RSV)antigen.Methods A total of 197 nasal-pharyngeal swabs (NPs)or nasal-pharyngeal aspirates (NPAs ) obtained from patients were tested by RSV assay kits, i. e., colloidal gold immunochromatography assay.The results determined by reverse-transcription polymerase chain reaction (RT-PCR)were taken as reference.Compared to the results of RT-PCR,the sensitivity of the kit was different when testing different types of specimens or specimensobtained from patients of different ages.Results A total of 95 (48.2%)samples were positive for RSV tested by RT-PCR.The sensitivity and specificity of colloidal gold immunochromatography assay were 34.7% and 100%, respectively compared with RT-PCR results.The positive rate of the assay was higher in testing NPAs than NPs (36.2% vs 8.6%,P < 0.01 ), which was the same in the sensitivity (22.1% vs 12.6%). The positive rate of colloidal gold year old,RT-PCR method should be used for RSV detection in clinical practice to avoid missed diagnosis.
