描述
 

Abbott RealTime CT/NG 测定是一种体外聚合酶链式反应 (PCR) 测定,用于在女性宫颈或阴道拭子样本、男性尿道拭子样本或男性和女性的尿液样本中直接定性检测沙眼衣原体的质粒 DNA 和淋病奈瑟菌的基因组 DNA。

  • 对于沙眼衣原体淋病奈瑟菌的双重检测具有高灵敏度和特异性 - 通过避免与包括非 STD 衣原体和奈瑟氏菌属在内的其他微生物发生交叉反应而获得准确结果 
  • 独一无二的 Abbott multi-Collect 样本采集试剂盒适用于多种样本类型 - 高效执行临床样本采集和实验室工作流程
  • multi-Collect 样本采集试剂盒采用可穿刺盖 - 无需打开每份样本的盖子,从而改进工作流程
可穿刺盖

用于 CT/NG 的 Abbott multi-Collect 样本采集试剂盒配有可穿刺盖。

  • 可刺穿盖使您无需打开每支试管的盖子 
    • 改进实验室工作流程
    • 最大程度地减少交叉污染
    • 减少重复性运动损伤的可能性
  • 无需拭子运输或手动挤压拭子
  • 无需样本离心或涡旋
  • 无需手动移液或添加裂解缓冲液

Abbott RealTime CT 与参照测定的比较研究1

从到 STD 门诊就诊的患者获取了总共 623 份样本,包括女性宫颈和阴道拭子、男性尿道拭子以及男性和女性尿液。始终先用参照测定采集试剂盒采集拭子样本,然后再用 Abbott multi-Collect 样本采集试剂盒采集拭子样本。

设计
 

开发理念

当今的临床分子诊断实验室必须对其沙眼衣原体淋病奈瑟菌患者结果的质量有信心。基于我们的实时 PCR 研发理念,Abbott RealTime CT/NG 经过精心设计以使其对单个样品的沙眼衣原体淋病奈瑟菌的检测兼具灵敏度和特异性。 

准确检测 CT 或 NG 取决于以下因素的组合:

  • 引物和探针设计(CT - 具有隐性质粒的双探针;NG - 具有 opa 基因的单探针)
  • 样品纯化
  • 纳入内部对照品
