The STI CNM Real-Time PCR Kit from Vitro S.A. (Spain) demonstrates high sensitivity and specificity, is cost-effective, and can detect the three main etiological agents of urethritis/cervicitis in a single multiplex PCR. Sexually transmitted infections (STIs) are a significant public health problem and a significant burden of morbidity and mortality in hospitals. The World Health Organization (WHO) estimates the number of daily infections to be 1 million. Currently, the number of infections and antimicrobial-resistant strains is rising. A rapid and accurate etiologic diagnosis is critical to solving this problem. In this study, we compared the STI CNM Real-Time PCR Kit using the Xpert CT/NG technique (Cepheid, USA) as Gold Standard for the diagnosis of and and EasyNAT MG (Ustar Biotechnologies (Hangzhou) Ltd., China) as Gold Standard for the diagnosis of infection. Regarding and , out of 200 samples, there was a match in 199 cases, with only one positive sample not being detected by the STI CNM Real-Time PCR Kit. This results in a sensitivity of 96% and a specificity of 100% for this kit. Diagnosing infection, out of 200 samples, the STI CNM Real-Time PCR Kit correctly detected all negative and positive samples, with 100% agreement compared to the reference technique. In summary, the STI assay has a very high sensitivity and specificity, comparable to other commercial diagnostic kits. Furthermore, it has the advantage of bundling the detection of the three main bacterial agents of urethritis/cervicitis, resulting in better cost efficiency.
西班牙Vitro S.A.公司生产的性传播感染(STI)CNM实时荧光定量PCR检测试剂盒具有高灵敏度和高特异性,性价比高,且能在一次多重PCR中检测出尿道炎/宫颈炎的三种主要病原体。性传播感染是一个重大的公共卫生问题,也是医院发病率和死亡率的重大负担。世界卫生组织(WHO)估计,每天的感染病例数达100万。目前,感染病例数和耐药菌株数量正在上升。快速准确的病因诊断对于解决这一问题至关重要。在本研究中,我们将STI CNM实时荧光定量PCR检测试剂盒与采用Xpert CT/NG技术(美国赛沛公司)作为淋病和沙眼衣原体诊断的金标准,以及将易安(EasyNAT)支原体检测试剂盒(中国杭州优思达生物技术有限公司)作为支原体感染诊断的金标准进行了比较。对于淋病和沙眼衣原体,在200份样本中,有199例结果相符,只有1份阳性样本未被STI CNM实时荧光定量PCR检测试剂盒检测到。该试剂盒对此的灵敏度为96%,特异性为100%。对于支原体感染的诊断,在200份样本中,STI CNM实时荧光定量PCR检测试剂盒正确检测出了所有阴性和阳性样本,与参考技术的一致性为100%。总之,STI检测方法具有非常高的灵敏度和特异性,与其他商业诊断试剂盒相当。此外,它具有同时检测尿道炎/宫颈炎三种主要细菌病原体的优势,从而具有更好的成本效益。
