Similarly, commutability of trueness controls or external quality assessment samples is essential when those materials are used to assess trueness of results for CSs. This report is part 1 of a 3-part series describing how to assess commutability of RMs.
30 de may. de 2023 · These recommendations represent a consensus developed through an IFCC Working Group comprising the current authors. In the following sections, we provide guidance for scientists who want to ensure reliable and reproducible clinical laboratory diagnostics using ML.
1 de mar. de 2018 · In this part, we describe the common requirements for the experimental design. In parts 2 and 3, we present 2 different statistical approaches for assessment of commutability. Part 2 is suitable for use when an RM is intended for use as a calibrator, a trueness control, or an EQA material ( 1 ).
A process is described to assess the commutability of a reference material (RM) intended for use as a calibrator, trueness control, or external quality assessment sample based on the difference in bias between an RM and clinical samples (CSs) measured using 2 different measurement procedures (MPs). ….
1 de mar. de 2018 · In the following description, an example data set is used to illustrate the process of assessing RM commutability by the RM's effectiveness to improve the agreement of results for a set of CSs after recalibration of the MPs with the RM. The analyses described assume ≥32 CSs ( 6) and ≤20 MPs ( 7 ).
