Abstract:

The construction of reference measurement system for laboratory medicine is an important guarantee for the metrological traceability of test results,and it is also an important basis for realizing the standardization and mutual accredit of test results. In the past half century,the reference measurement system of laboratory medicine based on reference measurement procedure,reference material and reference measurement laboratory has been basically formed and gradually improved. In recent 10 years,the development of reference measurement laboratory in China has made remarkable progress,however,the research on reference measurement procedure and reference material is relatively backward. The 6 papers published in this issue introduced the standardization of clinical chemistry,inter-accreditation evaluation of reference material,the establishment of reference measurement procedure and uncertainty evaluation,the development of reference material and matrix effect evaluation,and the application in in vitro diagnostic product（IVD）medical device and external quality assessment,hoping to further promote the research and application of reference measurement system in China.

Key words: Reference measurement system, Reference measurement procedure, Reference material, Reference measurement laboratory
