CLSI EP30 Abstract
Clinical and Laboratory Standards Institute EP30—Characterization and Qualification of Commutable Reference Materials for Laboratory Medicine provides guidance on characterizing and qualifying the fitness for use of commutable reference material (RM) as either a common calibrator or a trueness control for multiple measurement procedures. This guideline covers RM qualification requirements, characterization of homogeneity and stability, the assignment of quantity values, and determining RM value uncertainties. Three approaches for assessing commutability of RM are provided along with worked examples. Recommendations are made on how to report the results of the RM qualification process
