A1 - Steffen, Bernd T1 - How to interpret information from proficiency test exercises concerning the relative performance of accredited laboratories N2 - If the results from various proficiency tests are used to compare the performance of accredited and non-accredited laboratories, great care must be taken not to come to contradicting conclusions when interpreting them. This paper intends to draw the attention to various aspects that should be taken into account when trying to make conclusions from the relative performance of accredited laboratories in proficiency testing.
