摘要
目的：探讨新型 B 族链球菌（GBS）胶体金免疫层析试纸条的临床检测效果。方法选取202份女性的阴道或宫颈棉拭子标本，采用新型检测试剂与对照试剂作对比，进行临床应用评价。结果新型试剂最低检出浓度为105 CFU／ml，5～8 min 内即可观察结果；与对照试剂相比，考核试剂灵敏度更好，显色时间更短；检测的202份临床标本中，与对照试剂相比，197例样本检测结果一致，其余5例样本检测结果不符，阳性符合率达97.5％，阴性符合率达97.54％，总符合率为97.52％，Kappa 值0.948，一致性分析表明新型试剂与对照试剂具有很好的一致性。结论该新型试剂能有效的辅助诊断 B 族链球菌感染，具有较高的临床应用价值。
Objective To explore the effect of a novel colloidal gold immunochromatographic test strip for detection of group B streptococci （GBS）.Methods A total of 202 cases of swab of vagina or neck of uterus were collected,and they were detec-ted by novel strip and control strip to evaluate their clinical applications.Results Sensitivity of novel strip was about 105 CFU/ml and the detection time was about 5 to 8 minutes,and it showed better sensitivity and shorter detection time com-pared with control strip.In the 202 cases of clinical samples,the detection results of 197 cases were in consistent with the control strip,however,the detection results of 5 cases were not in consistent.The positive coincidence rate and negative coin-cidence rate were 97.5% and 97.54% respectively,and the total coincidence rate and Kappa value were 97.52% and 0.948 respectively.The consistency test showed no significant difference between this strip and control strip.Conclusion This method was a effective technology for diagnosing of infection caused by GBS,and had high value in clinical application.
