实验室间比对是实验室检测结果质量控制的常用方法之一,是根据预定条件,由2个或多个实验室就相同或类似的试验项目开展的组织、实施和评估活动。通过参加实验室比对,可以确定实验室对特定试验或测量的能力,了解实验室的检测水平,并进一步监控实验室的持续检测能力,识别实验室的问题并采取纠正措施,提高质量管理水平。1对象与方法1.1对象本省14个市(州)疾病预防控制中心。1.2质控样品的准备与分配向每个参加实验室发 Laboratory intercomparison is one of the commonly used methods for the quality control of laboratory test results. It is the organization, implementation and evaluation of two or more laboratories on the same or similar pilot projects based on predetermined conditions. By participating in laboratory comparisons, you can determine your lab’s ability to work on specific tests or measurements, learn about laboratory tests, and further monitor your laboratory’s ability to continuously test, identify laboratory problems and take corrective action to improve quality management . 1 Subjects and methods 1.1 Objects 14 provincial (prefecture) Centers for Disease Control and Prevention. 1.2 Preparation of quality control samples and distribution to each participating laboratory hair
