Description
技术领域
本发明涉及体外诊断试剂领域,尤其涉及一种需氧菌性阴道炎检测试纸及其制备方法。
背景技术
比利时著名妇产科专家Donders等于2011年综述需氧菌性阴道炎(AerobicVaginitis,AV)以菌群失衡、阴道炎症表现为特征。临床上阴道乳杆菌减少或消失,为需氧菌所取代,引起阴道不同程度的炎症。研究发现AV与BV类似,极易造成误诊,两者均可引起妇科、产科等相关疾病,如盆腔炎、早产、新生儿低体重、死胎、胎儿宫内感染和新生儿智力障碍等。
需氧菌性阴道炎是由需氧菌繁殖伴产过氧化氢的乳酸杆菌的缺失或减少,导致阴道黏膜充血、水肿,产生脓性分泌物的阴道炎症。常见病原菌包括B族链球菌、葡萄球菌、大肠埃希菌及肠球菌等需氧菌。AV阴道微生态表现:乳杆菌减少;优势菌多样化,常为需氧菌如革兰阳性链球菌、革兰阳性球菌、革兰阴性球菌或革兰阴性杆菌等;pH值常常大于4.5;过氧化氢(+);白细胞计数大于10个/HP;Donders评分≥3分;β-葡萄糖醛酸苷酶或凝固酶阳性。
国内外用于AV诊断的方法多为镜检法Donders评分或是微生物培养法,这两种方法费时,受操作人员的主观因素影响比较大,对临床常规或是问诊检验不便。目前市面上有采用干化学分析技术进行检测,如北京中生金域的发明专利《一种检测阴道分泌物中需氧菌的试剂盒及其制备方法》(专利申请号:200910244267)指出β-葡萄糖醛酸苷酶+凝固酶对AV可以有效诊断。但该发明只涉及β-葡萄糖醛酸苷酶及凝固酶两个项目,对白细胞酯酶(白细胞)、过氧化氢(乳酸杆菌)、PH值并没有涉及,检测不全面,且凝固酶法为两步法需要外加显色剂,反应需要孵育15min,操作不简便,检测时间长,有待改善。
发明内容

以下是本发明的一种需氧菌性阴道炎检测试纸的使用方法。
按照技术方案将制备好的5个项目试纸粘贴在基片上分裁成条制成需氧菌阴道炎五联检测试纸,或是由5个反应孔4组合需氧菌阴道炎五联检测试纸卡。
用无菌棉签或无菌拭子于阴道后穹窿处旋转10-20秒,以清晰见到棉签或拭子上有分泌物附着为准。将无菌拭子或是棉签采集样本,放入软试管中,每个样本加1.0ml生理盐水,反复涮洗,使样本充分洗脱,得到样本液;
取出阴道分泌物分析试纸或是试纸卡,在每个项目试纸孔中滴加样本20-30ul,约1滴;
放置在特定的仪器上进行检测,或者试纸条在37±1℃温育5分钟后,在1分钟内与色标卡对比判读结果。检测结果如下:
白细胞酯酶:
不显色(-)或淡紫色(+-)为阴性,提示正常;紫红色(+1~+3)为阳性,颜色深浅表明患者阴道内有不同程度的炎症反应。
过氧化氢:
呈红色或紫红色为阴性(-),提示可能有大量乳酸杆菌存在,阴道菌群正常;
呈淡红色(+-),弱阳性,提示可能有中量乳酸杆菌存在,可能阴道菌开始呈现不正常趋势或处于恢复期,需结合临床再判断,通常判阴性;不显色或淡黄色为阳性(+),指示阴道菌群失调,阴道环境病态或处于亚健康状态。
β-葡萄糖醛酸苷酶:
不显色为阴性(-),提示正常;红色或淡紫色为弱阳性(+-),显红色或紫红色为阳性(+),阳性或是弱阳性均提示阴道受以需氧菌为主的感染,阴道环境病态或处于亚健康状态;
凝固酶:
不显色或淡淡黄色为阴性(-),提示正常;浅黄色为弱阳性(+-);显黄色或紫黄色为阳性(+),阳性或是弱阳性表示受金黄色葡萄球菌、链球菌等需氧性细菌感染;
各个项目检测联检的临床意义如表1:
表1
按照《全国临床检验操作规程》,共试验600份阴道分泌物样本,按照微生物学检验方法共筛选出52份需氧菌类的样本,目测比对色标卡进行检测,采用本发明试剂盒的检测阴道分泌物中需氧菌群的结果如下:
阴性预测值为:97.5%;
阳性预测值为:93.2%;
由此可将,采用本发明的检测试纸对阴道分泌物中需氧菌类阴道炎的检出率在90%以上,可满足临床筛查或是辅助诊断的要求,且可用于女性日常阴道健康状况的监测。
以上所揭露的仅为本发明一种较佳实施例而已,当然不能以此来限定本发明之权利范围,本领域普通技术人员可以理解实现上述实施例的全部或部分流程,并依本发明权利要求所作的等同变化,仍属于发明所涵盖的范围。
