Standardization of TT4 and TT3 measurements

The mission statement of the C-STFT was to identify existing reference measurement systems, and/or, where needed, to develop them de novo. For TT4 and TT3, indeed, an existing SI- traceable reference measurement system (3) could be recommended to the IVD industry for implementation in accordance with the ISO 17511. For the key elements of that reference measurement system – primary calibrators (IRMM 468 & 469) and reference methods (isotope dilution-mass spectrometry, ID/MS), as well as reference laboratories offering measurement services – the committee refers to the database of the Joint Committee for Traceability in Laboratory Medicine (JCTLM) (4).
