title: Physiological time and the measurement of glomerular filtration rate.
abstract: Diverse physiological timescales in different animals can have an important influence on the measurement of biological variables. In vertebrates, the absolute and relative rates of glomerular filtration span several orders of magnitude. These differences have important implications for the logistics of measurement protocols in different species. A simple model is used to examine the importance of physiological time to the measurement of glomerular filtration rate.
