Fig. 1 Sigma Proficiency Assessment Chart of the Korean Association of Quality Assurance for Clinical Laboratory (KAQACL) proficiency testing (PT) in 2016 for Na+ (A), K+ (B), and Cl− (C). Allowable total error (TEa) values for Na+, K+, and Cl− were 5.0%, 8.0%, and 8.0%, respectively, which were from Rili-BAEK German guidelines for quality. Six points in the same color belong to one of eight peer groups and are from each of six specimens (CC-16-01-CC-16-06). Point size is proportional to the size of the peer group.Abbreviation: ISE, ion-selective electrode.
