两种阴道分泌物乳酸杆菌检测方法的临床意义初步探讨

Preliminary discussion on the clinical significance of two kinds of test methods on lactobacillus from vaginal discharge

目的探讨过氧化氢检测法和乳酸检测法用于检测阴道分泌物中乳酸杆菌的临床意义。方法采用过氧化氢检测法和乳酸检测法分别对586例阴道分泌物样本进行检测,并以革兰氏染色镜检作为金标准对比,分别比较两种检测法的临床性能。结果以革兰氏染色镜检方法为金标准,过氧化氢检测法检测乳酸杆菌的符合率可达94.9%,乳酸检测法检测乳酸杆菌的符合率为84.5%。结论过氧化氢检测法检测乳酸杆菌的符合率比较高,方便快捷,可以满足临床检测需要。

Objective To discuss the clinical significance of detection methods of hydrogen peroxide and lactic acid in testing lactobacillus from vaginal discharge. Methods Five hundred and eighty-six vaginal discharge samples were tested by hydrogen peroxide detection and lactic acid detection.The outcomes were compared by Gram staining mi-croscopy as a golden standard,clinical performance of two kinds of test methods was compared respectively. Results Gram staining microscopy as a golden standard,coincidence rate of lactobacillus by hydrogen peroxide detection reached 94.9%,while coincidence rate of lactobacillus by lactic acid method was 84.5%. Conclusion The coincidence rate of lactobacillus by hydrogen peroxide detection is relatively high,convenient and swift,which can meet the require-ments of clinical test.
