标准范围

ISO/TS 12869:2012规定了使用定量聚合酶链式反应(qPCR)检测和定量军团菌属和嗜肺乳杆菌的方法。它规定了一般方法要求、性能评估要求和质量控制要求。ISO/TS 12869:2012中规定的技术细节仅供参考。符合性能要求的任何其他技术解决方案都是合适的。ISO/TS 12869:2012旨在应用于所有类型的水（热水和冷水）的细菌学研究，除非悬浮物和/或伴随菌群的性质和/或含量干扰测定。这种干扰可导致对检测限和定量限两者的不利影响。结果表示为每升样品中军团菌属和/或嗜肺乳杆菌的基因组单位数。ISO/TS 12869:2012中描述的方法适用于所有类型的水。然而，一些添加剂，例如用于水处理的化学品，会干扰和/或影响该方法的灵敏度。qPCR方法不给出关于活细胞或死细胞的任何信息。

ISO/TS 12869:2012 specifies a method for the detection and quantification of Legionella spp. and L. pneumophila using a quantitative polymerase chain reaction (qPCR). It specifies general methodological requirements, performance evaluation requirements, and quality control requirements.Technical details specified in ISO/TS 12869:2012 are given for information only. Any other technical solutions complying with the performance requirements are suitable.ISO/TS 12869:2012 is intended to be applied in the bacteriological investigation of all types of water (both hot and cold), unless the nature and/or content of suspended matter and/or accompanying flora interfere with the determination. This interference can result in an adverse effect on both the detection limit and the quantification limit.The results are expressed as the number of genome units of Legionella spp. and/or L. pneumophila per litre of sample.The method described in ISO/TS 12869:2012 is applicable to all types of water. However, some additives, e.g. chemicals used for water treatment, can interfere with and/or affect the sensitivity of the method.The qPCR methods do not give any information about live or dead cells.
