Evaluation of Proficiency Testing Results Taking into Account their Uncertainties
A new composite score for evaluation the performance of proficiency testing participants is proposed. The score is based on combination of z-score, uncertainty of a participant's measurement result and uncertainty of the proficiency testing scheme's assigned value. The use of such composite score will allow to evaluate not only the participant's possibility to determine an analyte in corresponding matrix, but also his understanding of the uncertainty in the obtained analytical result. The score may be helpful for the laboratory's quality system and for the laboratory accreditation according to ISO 17025.
