Time profile of median plasma taurine concentrations in blood stored at room temperature and on ice. Each point represents the median value for that time, and the error bars represent the interquartile range. Median plasma taurine at room temperature is represented by solid circles, and median plasma taurine on ice is represented by triangles.
