Abstract
There is good correlation between the specific gravity and osmolality of urine obtained from neonates and adults, if specimens contain neither protein nor glucose. The regression equations between specific gravity and osmolality, however, differ considerably between the two age groups, maturation to the adult regression occurring within the first 5 years of life. Specifically derived regression equations should therefore be used when predicting urine osmolality from measurement of specific gravity in neonates.
摘要
如果新生儿和成人的尿液标本中既不含蛋白质也不含葡萄糖，那么尿液的比重和渗透压之间具有良好的相关性。然而，两个年龄组之间比重和渗透压的回归方程差异很大，在生命的前5年内会成熟到成人的回归状态。因此，当通过测量新生儿的尿液比重来预测尿液渗透压时，应使用专门推导的回归方程。
