The between method variability of patient results is a source of uncertainty that can have adverse consequences for patient safety and clinical outcomes. Globalisation requires that laboratory medicine results should be transferable between methods. Traceability in laboratory medicine aims to reduce between method variability so that results are independent of time or location. Application of the metrological traceability chain facilitates a universal approach based around the preparation, adoption and use of higher order international commutable reference materials and reference measurement procedures, supported by expert reference laboratories. Global collaboration is required, involving several different stakeholder groups ranging from international experts to laboratory medicine specialists in routine clinical laboratories.
患者检测结果的方法间变异性是不确定性的一个来源，可能对患者安全和临床结果产生不良影响。全球化要求检验医学结果应在不同方法之间具有可转移性。检验医学中的可追溯性旨在减少方法间变异性，以使结果不受时间或地点的影响。计量溯源链的应用促进了一种通用方法，该方法围绕高阶国际可互换参考物质和参考测量程序的制备、采用和使用，并得到专家参考实验室的支持。这需要全球合作，涉及从国际专家到常规临床实验室的检验医学专家等几个不同的利益相关者群体。
