【摘要】 目的　评价一种氧化酶拭子检测技术在男性急性尿道炎临床快速鉴别诊断中的应用价值。方法　用氧化酶拭子直接蘸取 189例门诊男性急性尿道炎可疑病例尿道分泌物 ,并观察棉拭子上有无氧化酶反应 ,同时接种于TM培养基。比较两种检测手段的检测结果。结果　 189例标本中TM培养和氧化酶反应的阳性率分别为 78.8%和 79.9% ,两法总符合率为 91.5 % (31+14 2 /189)。与培养法比较 ,氧化酶拭子敏感性 95 .3% ,特异性 77.5 % ,阳性预测值 94 % ,阴性预测值 81.6 % ,两法无显著性差异 (P >0 .0 5 )。结论　氧化酶拭子检测技术能对淋菌性和非淋菌性尿道炎进行快速初步鉴别且有较高的敏感性和特异性 ,方法简便、成本效益性好。更多还原

【Abstract】 Objective To assess the applied value of an oxydase swab in early differential diagnosis of male acute urethritis.Methods The urethral secretions in 189 suspected cases were examined with oxydase swab and inoculated with TM medium immediately.Results The results showed that the positive rate of 189 cases was 78.8% and 79.9% in TM medium and oxydase swab respectively.The coincidence rate of two methods was 98.7%(149/151).To compare with culture method,the sensitivity of oxydase swab was 95.3%,specificity was 77.5%,positive prediction values was 94%,negative prediction values was 81.6%. Conclusions Oxydase swab is a simplified,rapid and high sensitivity and specificity method for diagnosis and differential diagnosis of acute urethritis in male.更多还原
