IFCC Working Group Recommendations for Assessing Commutability

Commutability is an important concept in determining traceability and the relationship among different methods that are used to measure the same analyte but just how to describe and classify commutable materials is not always straightforward.  The March 2018 issue of Clinical Chemistry published a series of three reports from the Working Group on Commutability of the International Federation of Clinical Chemistry and Laboratory Medicine, or IFCC, that describe recommendations for assessing commutability.
