Repeatability and reproducibility of the luminescent bacteria bioassay

This paper presents the statistical analysis of the results of an inter-lab oratory study for the luminescent bacteria toxicity bioassay. It also conta ins a discussion on the statistical methods for the presentation and refine ment of the evaluation of the precision of an assay method (including intra - and inter-laboratory variability), with special emphasis on the rejection of outliers, and the use of standardized parameters, like the repeatabilit y and reproducibility values.
