Commutability Assessment of Materials for Serum Copper Measurement Using the IFCC Difference-in-Bias and the CLSI EP30 Approaches

Background: Evidence on the commutability of material for serum copper when assessing multiple material categories and assay pairs remains limited. Methods: We evaluated 21 reference materials for serum copper across four routine colorimetric systems and an inductively coupled pl...
