Standardization of clinical laboratory data and reference intervals
Journal Title: Journal of Analytical Bio-Science - Year 2011, Vol 34, Issue 3
Abstract
For clinical laboratory data to be utilized in the diagnosis and prevention of disease, their reliability must be verified. To ensure the reliability of routine test data in all laboratories, it is necessary for it to be consistent with the traceability chain for each constituent, and for the values to be transferred from that measurement system appropriately. The nationwide standardization of measurement data by the utilization of both reference and control materials will enable us to ensure the widespread and long-term reliability of clinical laboratory data. To achieve this system-based consistency, the laboratories must verify the accuracy of test data, so that the reference interval of laboratory data for disease screening can be shared by different institutes. Resarding the improved reliability of measurement values, two new reference-intervals, studies have beenpublished; one by the Japanese Association of Medical Technologists, which establishes the reference intervals that can be shared by all clinical laboratories, and another that addresses the research results of differences between areas in Asian districts regarding the reference values of clinical tests. Thus, the latest knowledge about the standardization of both reference intervals and measurement values will be will be widely disseminated.
