Popis: The reliability of salivary testosterone assays was evaluated by nine laboratories in four countries. Each laboratory used its own RIA procedures to assay samples from a set of 100 male and 100 female subjects. Agreement among the laboratories on mean scores was within the range reported by Read (Ann N Y Acad Sci 1993; 694: 161-76). Overall agreement on individual scores, as indicated by the intraclass correlation coefficient computed within subjects across laboratories, was r = 0.87 for men and r = 0.78 for women. Mean agreement between each laboratory and the combined set of all other laboratories (via Fisher's Z-transformation) was r = 0.61 for men and r = 0.58 for women. We take these latter values to be the best estimates of the average reliability of laboratories in their ordering of individual samples.
