Abstract:
In laboratory medicine, accurate and comparable measurement results are required for correct medical interpretations.Metrological traceability is an important approach to achieve standardization of test results obtained with different analytic systems.Traceability is established by a series of comparative measurements using a hierarchy measurement procedures and calibrators.Specificity of the lower order methods and commutability of the calibrators are the prerequisites in establishing traceability.The higher order procedures and calibrators in the hierarchy are called reference systems and it is important that the reference systems are metrologically qualified.The Joint Committee for Traceability in Laboratory Medicine (JCTLM) has been formed to identify the reference systems worldwide.In conclusion, the concept of metrological traceability has been introduced to the filed of laboratory medicine.Development and implementation of reference systems in laboratory medicine are expected.
