This graph (modified from Malmud LS et al.) represents normal curves in young people taken in anterior view, which can be used as a reference in children, in case proper laboratory data are not available. Half time can be roughly estimated from the range curves. As far as solids, between 70 min to 140 min approximately and the mean 90 min. In the case of liquids, between 20 min and 40 min approximately and the mean 30 min.
