描述
 

本测定旨在与临床表现和其他实验室标志物结合使用以作为开始治疗的指征,并适用于辅助监测(以血浆或全血中 DNA 水平变化来衡量的)病毒对抗病毒治疗的反应。

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。

用于 CT 的 Abbott multi-Collect 样本采集试剂盒现在可提供可穿刺盖!

可穿刺盖

可穿刺帽不再需要打开每个试管,从而:

  • 改进了实验室工作流程
  • 最大程度减少了交叉污染
  • 减少重复性运动损伤的可能性

其他获益包括:

  • 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

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 经过精心设计以使其对单个样品的沙眼衣原体检测兼具灵敏度和特异性。

准确检测 CT 取决于以下因素的组合:

  • 引物和探针设计(具有隐性质粒的双探针)
  • 样品纯化
  • 纳入内部对照品

单链线性探针
