Remarks

A cycle of the program involves twelve distributions and covers a two year period. Following the analysis of two lyophilized controls of different concentrations, participants submit data via a web application and receive reports and information on their performance through the Internet. The analytes are statistically processed on the overall results, regardless of the methodology. After the elimination of outliers (elimination in two passes of all results > +2.5SD or < -2.5SD of the mean value), the “consensus” mean, namely the mean from all individual results, is used as target value. Statistical evaluation is also related to the method or the analyzer used and includes three different charts: distribution histograms, Levey-Jennings charts and Youden plots. The software of ESEAP permits the grouping of methods and instruments (analyzers), the enhancement of the statistical evaluation of the results, as well as the evaluation of reproducibility of the measurements using 4 samples during each year. Furthermore, at the end of each two-year cycle, participants are assessed through an original scoring and ranking system, allowing them to follow their individual performance across time and their position among all other laboratories participating in the cycle. There is also a monthly program with twelve distributions of two samples per year.
