In vitro diagnostic medical devices. Requirements for international harmonisation protocols establishing metrological traceability of values assigned to calibrators and human samples1 Scope This document specifies requirements for a protocol implemented by an international body to achieve equivalent results among two or more IVD MDs for the same measurand for cases where there are no reference measurement procedures and no fit for purpose certified reference materials or international conventional calibrators. In this case, the harmonisation protocol defines the highest level of metrological traceability for the stated measurand.
