摘要
目的对比研究PCR法及细菌培养法在应用于孕妇产前B族链球菌感染检测中的意义与价值。方法该研究病例观察时间段为2016年1—6月,方便收集该院产科收治疑似B族链球菌感染产妇共100例作为观察对象,对患者临床资料进行回顾性分析。所有患者分别应用PCR法以及细菌培养法进行检测。以最终诊断结果为金标准,对比PCR法与细菌培养法在孕妇产前B族链球菌感染检测中的准确度以及特异性差异。结果应用PCR法对B族链球菌感染检测的准确度为97.37%(74/76),特异性为95.83%(23/24),应用细菌培养法对B族链球菌感染检测的准确度为81.58%(62/76),特异性为70.83%(17/24)。两组对比,PCR法用于孕妇产前B族链球菌感染检测准确度、特异性均显著高于细菌培养法,差异有统计学意义(P<0.05)。结论在孕妇产前B族链球菌感染检测中,应用PCR法的检测效果明显优于细菌培养法,具有准确度高、特异性高的优势,值得推广应用。
Objective To compare and research the significance and value of PCR and germiculture in the infection test of prenatal group b streptococcus. Methods 100 cases of delivery women suspected with group b streptococcus admitted and treated in our hospital from January 2016 to June were convenient selected and the clinical data were reviewed and all patients were tested by the PCR and germiculture, and the differences in the accuracy and specificity between the two methods were compared by taking the final diagnostic results as the golden standards. Results The accuracy and specificity of the PCR were obviously higher those of germiculture,[97.37%(74/76), 95.83%(23/24) vs 81.58%(62/76), 70.83%(17/24)],and the differences were statistically significant(P<0.05). Conclusion The test effect of PCR method in the prenatal group b streptococcus of delivery women is obviously better than that of germiculture with high accuracy and specificity, and it is worth promotion and application.
