Abstract: Proficiency testing is an important means of laboratory quality assurance. The determination of the specified value of proficiency testing samples could affects the accuracy of the evaluation of proficiency testing results directly. It is a common method to determine the specified value by using the agreed value of participants. The accuracy of this method is limited by the number of participants. When the number of participants is small, the uncertainty of the specified value determined by this method is large. If the number of participants is too small, it can not even determine the result of proficiency testing.

Key words: proficiency testing, participant, consensus value, specified value
