Figure 2From: Ex-vivo changes in amino acid concentrations from blood stored at room temperature or on ice: implications for arginine and taurine measurements Time profile of median plasma arginine and ornithine concentrations in blood stored at room temperature. Each point represents the median value for that time, and the error bars represent the interquartile range. Median plasma arginine is indicated by triangles, and ornithine by solid circles.Back to article page
