Objective To evaluate the measurement uncertainties(MU)for the determinations of serum potassium ion(K~+),sodium ion(Na~+)and chlorinum ion(Cl~-)by ion selective electrode(ISE),and to improve the quality. Methods According to the Medical Laboratory-Evaluation and Expression of Uncertainty of Measurement published by China National Accreditation Service for Conformity Assessment(CNAS)in 2012,the relative expanded uncertainties(U_(rel))of serum K~+,Na~+ and Cl~-were assessed by top-down method with the data o...
